摘　　要：利用城市蔓延指数和InVEST模型,分析了2000~2020年长江流域干流和支流流经的19个行政区域省会城市的城市蔓延时空变化和城市蔓延对生态系统服务的影响,并探究城市蔓延区域对生态系统服务的影响因素.结果表明:(1)2000~2010年47.37%的城市处于蔓延状态,2010~2020年73.63%城市处于蔓延状态.(2)2000~2020年长江流域(中心城区)省会城市的生境质量均值、粮食和肉类生产服务总量和碳储量总量的下降比率分别为4.25%、7.03%和4.53%,产水总量的上升比率为12.10%.(3)因城市蔓延导致的生态系统服务损失量中生境质量下降最明显,2010~2020年损失量占2000年平均生境质量的71.56%.(4)选取土地利用转化、社会经济和气候对生态系统服务的影响进行相关分析,土地利用转化和社会经济是最大影响因素.This study used the urban sprawl index and InVEST model to analyze the spatiotemporal changes of urban sprawl and its impact on ecosystem services in 19 provincial capital cities along the main and tributary streams of the Yangtze River Basin from 2000 to 2020.It also explored the factors influencing ecosystem services in the urban sprawl areas.This study found that:(1)47.37%and 73.63%of cities experienced urban sprawl during 2000~2010 and 2010~2020,respectively.(2)From 2000 to 2020,the average habitat quality,total food and meat production services,and total carbon storage of provincial capital cities in the Yangtze River Basin(central urban area)decreased by 4.25%,7.03%,and 4.53%,respectively,while the total water production increased by 12.10%.(3)The loss of ecosystem services due to urban sprawl was the most significant in terms of habitat quality,with a loss of 71.56%from 2010 to 2020 compared to 2000.(4)A correlation analysis was conducted on the impact of land-use conversion,socio-economic factors,and climate on ecosystem services,and it was determined that land-use and use conversion and socioeconomic factors were the most influencing factors.
