中文摘要
气候变化对人类构成了巨大的威胁,掌握生态系统碳储量的时空变化有助于制定更合理的政策和策略来应对这一问题。文章以渝东南区域为例,应用PLUS及InVEST模型对土地利用及生态系统碳储量进行多情景模拟及评估,并在此基础之上通过最邻近指数、核密度及标准差椭圆对减少区域的空间特征进行分析。结果表明:1)2002—2022年,土地利用类型的转换主要是灌木转换为林地和耕地。在2032年的不同模拟情景下,耕地和建设用地均具有增长的趋势,主要增长来自于林地,其余用地变化的幅度较小。2)2002—2022年碳储量总量在逐渐减少,预计在2032年碳储量仍然是减少的趋势,且碳储量减少的幅度依次为EPS

英文摘要
Climate change poses a great threat to human beings, and understanding the spatiotemporal variations of ecosystem carbon storage can help formulate more reasonable policies and strategies to address this issue. This paper takes southeast Chongqing as an example to apply PLUS and InVEST models to simulate and evaluate its land use and ecosystem carbon storage in multiple scenarios, and then analyze the regional spatial characteristics of the storage decreased through the nearest neighbor index, kernel density and standard deviation ellipse. The results show: 1) Between 2002 and 2022, the conversion of land use is concentrated in the conversion of shrubs to forests and croplands. Under different simulated scenarios in 2032, both cropland and construction land present an increasing trend, converted mainly from forestland, while the land uses remain smaller changes; 2) The total carbon storage amount is gradually decreasing from 2002 to 2022. It is expected that the carbon storage will be still in a decreasing trend towards 2032, and the magnitude of carbon storage reduction is ordered as EPS
