    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.

    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.

    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.

    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.
