- “在“碳中和”目标下，土地利用领域面临新挑战。专家提出加强国土空间碳监测、低碳土地利用技术研究，为实现碳中和提供借鉴。”摘要：Under the target of carbon neutrality, how to increase carbon sink and reduce carbon emissions through land use optimization is both a new opportunity and a challenge for the academic research and the natural resource management department. In this paper, we systematically summarized several main research progress, including the mechanism how land use causes carbon source/sink change, the influence of land-use change on carbon source/sink, the carbon monitoring in space, and the low-carbon land use. Then, we summarized the research shortages and the challenges in the future study. By considering both the carbon neutral target and the development requirements in a new era, this study proposed several future research areas that need to be strengthened: to monitor carbon emissions in high resolution by integrating multisource data, to develop the integrated low-carbon land use technology from multi-perspectives, and to explore the intelligent platform for quick calculation of land-use-change caused carbon source/sink, etc. This study also proposed some policies for governments, including making the dual carbon objective and low carbon concept a constraint requirement through the whole preparation and implementation process of land spatial planning, adding carbon evaluation to individual land use management process, and strengthening low-carbon land use for production-living-ecological lands according to their land use characters, etc. This research can provide references for carbon neutrality promotion from the aspect of land use, both for scientific research and practical applications.关键词：land use;carbon source/sink;carbon neutrality;low-carbon land use856|714|0更新时间：2025-02-21
- “据最新研究，国家生态文明试验区建设有效促进区域经济增长和节能减排，为生态文明建设提供新思路。”摘要：This article utilizes the first batch of three national pilot zone (Fujian, Jiangxi, Guizhou) for ecological conservationas a quasi-natural experiment. Based on China’s provincial panel data from 2009 to 2022, it employs the synthetic control method and mediated effects test models to examine the impact of pilot policies for ecological civilization construction on regional economic growth, energy conservation, and emission reduction. The findings suggest that the national pilot zone for ecological conservation has significantly increased GDP and per capita GDP, while also reducing carbon emission intensity and energy consumption per 10 000 yuan of GDP. These results confirm that pilot policies for ecological civilization construction are beneficial for achieving both regional economic growth and energy conservation and emission reduction. Furthermore, this study reveals that pilot policies for ecological civilization construction have a certain heterogeneous impact on regional economic growth and energy conservation, and emission reduction. The pilot policies for ecological civilization construction can drive regional economic growth by leveraging the effects of ecological environment improvement, green technology innovation, and industrial structure upgrading, and can promote regional energy conservation and emission reduction by relying on the effects of ecological environment improvement, green industry development, and green technology innovation.关键词：ecological civilization construction;pilot policies;economic growth;energy conservation and emission reduction;national pilot zone for ecological conservation162|126|0更新时间：2025-02-21
- “在“双碳”背景下，成渝地区双城经济圈碳排放时空演变特征及多情景模拟研究，为区域减碳策略制定提供重要参考。”摘要：Revealing the spatiotemporal evolution characteristics of regional carbon emissions and simulating the trend of carbon emission evolution in multiple scenarios under the background of “dual carbon” are of great significance for formulating reasonable regional carbon reduction strategies and addressing global climate change. By constructing a carbon emission assessment index system and a carbon emission system dynamics model, this study analyzes the spatiotemporal evolution of carbon emissions in the Chengdu-Chongqing Economic Circle in 2015 and 2020, and simulates the carbon emission trends of the region from 2021 to 2050 under multiple scenarios, adhering to a shared socioeconomic pathway. The results of this article indicate that: in 2015 and 2020, the total carbon emissions of the Chengdu-Chongqing Economic Circle were 527.647 9 and 522.498 6 million tons, respectively, and the high-value areas of carbon emissions were mainly concentrated in the central urban areas of Chengdu and Chongqing, while the low value areas were distributed around the central urban areas. From 2021 to 2050, under different shared socioeconomic pathways, the total carbon emissions of the Chengdu-Chongqing Economic Circle will continue to increase. Compared with the intermediate scenario, the fossil fuel scenario in 2050 will increase by 7.91%, while the sustainable scenario will decrease by 6.68%. The optimal carbon emission path for the future Chengdu-Chongqing Economic Circle is the sustainable path scenario. By reasonably coordinating the relationship between population, economy, industry, and energy, sustainable development of the Chengdu-Chongqing Economic Circle can be achieved.关键词：Chengdu-Chongqing Economic Circle;carbon emission;system dynamics model;shared socioeconomic pathways177|268|0更新时间：2025-02-21
- “金沙江干热河谷土地利用变化与碳储量关系研究，为区域生态环境治理提供重要参考。”摘要：Exploring the relationship between regional land use change and carbon storage can provide robust policy support for optimizing land spatial structure and maintaining regional carbon balance. The InVEST model was used to analyze the relationship between land use changes and ecosystem carbon storage in the dry-hot valley of the Jinsha River region for the periods of 1995―2020. The results show that: 1) From 1995 to 2020, the study area experienced a significant reduction in forest and grassland areas, while the areas of water bodies and construction land increased. 2) From 1995 to 2020, the carbon storage in the study area exhibited a spatial distribution characterized by higher in the center, lower around the edges, and higher in the west than in the east. Overall, it showed a declining trend, with a cumulative loss of 30.72×105 t. The reduction in forest and grassland areas was the main reason for the decrease in carbon storage. The PLUS model and the InVEST model were used to predict the land use changes and the spatial distribution of carbon storage in the dry-hot valley of the Jinsha River region for the period of 2020―2030 under three different scenarios, respectively. The results show that: By 2030, under the scenarios of natural growth, ecological protection, and farmland conservation, the carbon storage will decrease by 12.90×105 t, 3.60×105 t, and 7.23×105 t respectively compared to 2020. Ecological protection scenarios can effectively mitigate carbon losses and provide an important reference for regional ecological environment management.关键词：carbon storage;land use;dry-hot valley;InVEST model;PLUS model218|261|0更新时间：2025-02-21

Spatial analysis and other methods are used to analyze the spatiotemporal evolution of cultivated land carbon storage in the karst region of Yunnan, Guangxi, and Guizhou. Based on the annual rate of change in total carbon storage, the carbon sink capacity of cultivated land in various counties in the karst region of Yunnan, Guangxi, and Guizhou is evaluated, and carbon source/sink areas are distinguished. The results show that: 1) From 2000 to 2020, the cultivated land area increased by 1 950.67 km2, and the soil carbon storage of cultivated land increased by 3.5×107 t, indicating that regional cultivated land has the potential for carbon sequestration; in terms of spatial distribution, soil carbon storage in cultivated land exhibits a distribution pattern of “high in the southeast and low in the northwest”. 2) From 2005 to 2020, the cultivated land in karst areas mainly exhibited carbon sequestration (NEP>0), the average NEP for multi-year cropland is 78.45 g·m-2·a-1. From 2005 to 2020, the net ecosystem productivity (NEP) of county-level cultivated land in karst areas showed a downward trend, and the total NEP decreased from 2.46×1014 g in 2005 to 1.12×1014 g in 2020. 3) The overall carbon sink function of southwestern karst cultivated land is complex and uneven, with 221 carbon sink areas and scattered carbon source areas in the northwest and southeast regions of Yunnan Province.关键词：arable land;carbon stocks;net ecosystem productivity;carbon sink areas165|34|0更新时间：2025-02-21
- “最新研究揭示了四川省凉山彝族自治州黑沙河泥石流滩地系统敏感性和景观脆弱性评价，为区域管理及可持续发展提供重要参考。”摘要：The evaluation of systemic sensitivity and landscape vulnerability holds significant implications for regional management and sustainable development. Taking the Heisha River waste-shoal land system in Liangshan Yi Autonomous Prefecture, Sichuan Province, as the research object, this research analyzed the characteristics of land-use change of 2014, 2018, 2022 based on historical remote sensing data. Considering socio-ecological factors, the relationship between the spatial and temporal distribution pattern of systemic sensitivity and landscape vulnerability and its driving factors were evaluated by analytic hierarchy process and entropy weight method, Geodetector, spatial autocorrelation and other methods. The results showed that, the land use types of the study area were mainly cultivated land and forest land, and the overall trend showed a decrease in cultivated land and an increase in forest land and construction land. Systemic sensitivity showed a decreasing trend over time and a spatial pattern of being lower in the west and higher in the east, exhibiting a spatial positive correlation of high-high clustering and low-low clustering. Geographical detector analysis revealed that annual average rainfall, elevation, annual average temperature, and distance from fault zones are the main driving factors of Systemic sensitivity, with the interaction of natural and anthropogenic factors exacerbating the changes in systemic sensitivity.Furthermore, landscape vulnerability showed an increasing trend followed by a decrease over time, with a spatial distribution characteristic of being higher in the west and lower in the east, which is mismatched with the spatial distribution of systemic sensitivity. The findings of this study can aid in optimizing disaster prevention and mitigation strategies and regional development policies.关键词：debris flow waste-shoal land;land use;systemic sensitivity;landscape vulnerability;spatio-temporal distribution89|39|0更新时间：2025-02-21

Patterns of Ecosystem Health Diagnosis and Evolution Based on the VORS Framework in a Karst Basin AI导读
“在喀斯特流域生态系统健康研究领域，专家构建了评价指标体系，为可持续发展提供环境保护和修复建议。”摘要：Research on the evolution of ecosystem health in karst basins can clarify important factors affecting ecological health and provide environmental management recommendations for sustainable development. Based on remote sensing, landscape theory, vigor-organization-resilience-services (VORS) framework and the characteristics of rocky desertification, we constructed a karst ecosystem health evaluation index system was constructed in this study, and we use it to couple with the TOPSIS to evaluate the health levels of vigor(v), organization(o), resilience(r), services(s) and ecosystem health index (EHI) from 1990 to 2020 in Hongfeng Lake, a typical karst watershed, and combined with the Theil-Sen Median method and the Mann-Kendall test to clarify the trend distribution characteristics of each index. The results show that: ① The ecosystem dimensions of Hongfeng Lake basin are at a good level during 1990-2020. There is no significant change in ecosystem vigor, while ecosystem organization and resilience show a slight improvement trend, and ecosystem services exhibit polarization. ② Ecological health grades show a bipolar evolution. The improvement areas include the northern forest belt, southern mountains, and central karst hills; the deterioration areas are centered on rapidly expanding urban areas and intensive agricultural zones, extending outward. ③ The influencing factors of different ecosystem dimensions vary. Land use is the dominant factor affecting ecosystem health. In karst areas, the combined effect of rainfall and slope on ecosystem health is synergistic, where “1+1>2”.关键词：ecosystem health;vigor-organization-resilience-services (VORS);spatiotemporal evolution;Hongfeng Lake basin111|171|0更新时间：2025-02-21 - “在乡村生态产品价值实现领域，专家构建演化博弈模型，分析企业、居民、地方政府三方行为策略，为促进乡村振兴与共同富裕提供解决方案。”摘要：The realization of the value of rural ecological products serves as a crucial path to promote rural revitalization and common prosperity. An evolutionary game model is established to study the behavioral strategies of enterprises, residents and local governments in the realization of the value of rural ecological products in southwestern China. The Matlab simulation analysis is applied to investigate the impact of changes in various variables on the evolutionary game outcomes. The results reveal that the behavioral strategies of enterprises, residents and local governments are mutually influential: The higher the expected returns of enterprises, the faster the evolutionary speed of enterprises choosing cooperative strategies. The more rewards residents receive for active participation, the faster the evolutionary speed of residents selecting active participation strategies. The government’s reward and punishment mechanism has a significant impact on the strategic choices of enterprises and residents, with a reasonable degree of reward and punishment accelerating the evolutionary speed of their strategic choices. Notably, the punitive mechanism has a greater promotional effect on enterprises than the reward mechanism. The stable strategies for the realization of the value of rural ecological products in Southwest China are characterized by enterprises’ emphasis on residents’ interest demands, active participation from residents, and lenient supervision from local governments.关键词：rural revitalization;Southwest China region;ecological products;evolutionary game;simulation analysis106|86|0更新时间：2025-02-21
- “在山地型城市生态系统文化服务领域，重庆专家运用ArcGIS分析技术等方法，量化研究了文化服务供需空间关系，为城市生态系统价值效益转化提供理论支撑。”摘要：The supply and demand spatial relationships of cultural ecosystem services (CES) in mountainous high-density urban ecosystems are intricate. In the new phase of high-quality development in urban living environments, conducting a quantitative study on the spatial relationships of CES in cities from a supply-demand perspective contributes to the transformation of the value of urban ecosystems and enhances overall social well-being. Taking the mountainous city of Chongqing as the study area, a quantitative study of the spatial distribution and characteristics of CES supply and demand, the balance between supply and demand, and the spatial relationship has been carried out based on multi-source data using ArcGIS analysis techniques, computer vision recognition and spatial correlation analysis. The results show that: 1) The CES supply of Chongqing presents a spatial pattern of “large aggregation and small dispersion”, and has a clustering feature of “center periphery”. The natural conditions of the mountainous background have a significant impact on it with high-high value aggregation zones mainly located in and around the built-up areas in a continuous manner, while low-low value aggregation zones are mainly dispersed in the peripheral zones, which is significantly influenced by the natural background conditions of the mountainous terrain; 2) The spatial distribution of CES demand is extremely uneven, with a clear centripetal distribution characteristic of high-value demand areas, but with differences in the spatial distribution of different types of CES demand; 3) There is a weak spatial structural similarity between CES supply and demand, and the balance of supply and demand shows significant spatial heterogeneity, with a prominent mismatch between supply and demand, with the core area of the “Two Rivers and Four Banks” under great pressure of supply, while the peripheral areas have a high CES supply, but low actual demand. The results of the study can provide theoretical support for the regulation and optimisation of CES in mountainous cities.关键词：mountainous cities;cultural ecosystem services;supply-demand space;supply and demand balance;Chongqing113|116|0更新时间：2025-02-21
- “在生态系统服务领域，贵阳市喀斯特山区研究揭示了非线性约束关系，为喀斯特环境管理提供新思路。”摘要：Ecosystem services usually exhibit trade-offs or synergies relationships with each other; however, there is also a new type of constraint relationship between them. Due to the spatial heterogeneity of the environment in karst regions, existing findings on constraint relationships of ecosystem services in non-karst areas may not be applicable to karst environments. We explore the non-linear constraint relationship between two pairs of karst ecosystem services using the constraint line method combined with restricted cubic spline analysis. The results show that nutrient retention-water yield showed a positive convex curve constraint relationship, soil conservation capacity-water yield and soil conservation capacity-nutrient retention showed a negative convex curve constraint relationship, habitat quality-water yield and habitat quality-soil conservation capacity showed a hump-shaped curve constraint relationship, and habitat quality-nutrient retention showed a convex-waved curve constraint relationship.关键词：ecosystem services;constraint relationships;karst;trade-off synergy88|103|0更新时间：2025-02-21
- “在云南省滇重楼生长分布研究中，专家运用多种模型预测潜在适生区，筛选出最适宜种植区域，并分析气候变化对适生区的影响。”摘要：By collecting the distribution points of Paris polyphylla var. yunnanensis in Yunnan Province and integrating 19 influencing factors, six species distribution models (GAM, GLM, GBM, RF, SVM, and MaxEnt) were used to predict the potential suitable habitats for Paris polyphylla var. yunnanensis in Yunnan Province. The RF model, which had the highest prediction accuracy, was selected as the predictive model. Based on the prediction results, the primary factors affecting the growth and distribution of Paris polyphylla var. yunnanensis in Yunnan Province were explored. To further identify the areas with the highest planting potential, the cropland fragmentation in suitable habitats across different counties was considered to select the most suitable planting areas. In consideration of future climate change, the spatiotemporal evolution of suitable habitats under different climate scenarios (SSP1-2.6, SSP2-4.5, and SSP5-8.5) for the periods 2021―2040, 2041―2060, and 2061―2080 was studied. The results show that the total suitable habitat area for Paris polyphylla var. yunnanensis in Yunnan Province is 97 030 km², primarily located in the northwestern and central-eastern regions. The suitable habitat covers 67 counties in total. Considering the impact of cropland fragmentation on the industrial cultivation of Paris polyphylla var. yunnanensis, 12 counties were identified as having the most suitable cropland for planting. Under climate change conditions, the suitable habitat area for Paris polyphylla var. yunnanensis in Yunnan Province is expected to shrink and shift eastward, with the habitat’s centroid moving toward the southeast.关键词：climate change;cultivated land;fragmentation;Paris polyphylla var. yunnanensis;suitable area97|62|0更新时间：2025-02-21
- “在应对气候变化和人类活动影响下，我国主要江河径流变化的水库群适应性调控策略研究取得进展。专家构建了溪洛渡梯级-三峡梯级水库群多目标联合调度模型，设计了适应性调控措施组合方案集，通过仿真模拟分析了调控机理，评估了不同方案的适应性调控效果。”摘要：Due to the impacts of climate change and human activities, the runoff of major rivers in China has undergone significant changes. Study on adaptive regulation strategies for reservoir groups in response to these variations in runoff is of great importance. A multi-objective joint scheduling model for the Xiluodu cascade and Three Gorges cascade reservoirs system was developed to facilitate adaptive regulation simulations. Additionally, a set of combined schemes was designed based on optimization of scheduling modes, utilization of flood resources, and adjustment of water-use behaviors. Through simulation analysis, the regulation mechanisms were examined, and the adaptive regulation effects of different schemes were assessed. The results indicate that: 1) due to reduced runoff, the total power generation of the Xiluodu cascade and Three Gorges cascade reservoirs under conventional scheduling decreased by 3.578 billion kW·h. By adopting joint scheduling of the reservoir groups, the cascade hydropower stations were able to increase generation by 625 million kW·h. 2) When the restricted water level during flood period of the Three Gorges Reservoir was raised to 153 m, the negative impacts of decreased river runoff on the overall benefits of the cascade reservoir groups were effectively mitigated. 3) Additionally, raising the restricted water level during flood period of the Three Gorges Reservoir to 150 m, along with upstream water conservation of 20%, allowed the total power generation of the cascade reservoirs to exceed that of the conventional scheduling during the baseline period. Utilizing non-engineering measures to increase the utilization of flood resources, adjusting upstream water-use behaviors, and optimizing the scheduling operation of the hydropower system are effective regulatory measures to mitigate the impacts of river runoff changes on the hydropower system.关键词：reservoir group;adaptive regulation;runoff change;multi-objective optimization72|49|0更新时间：2025-02-21
