摘　　要：[目的]评价北京市生态环境状况对推进城市建设和经济发展,为实现生态环境保护和经济社会可持续发展具有重要的现实意义。[方法]耦合区域绿度、湿度、干度和热度特征的遥感生态指数(remote sensing ecological index, RSEI),探究了1990—2020年北京市生态环境质量时空动态,并辅以Sen趋势分析、Manna-Kendall突变点检验法和多元回归和结构方程模型,分析了不同环境因子对北京市生态环境质量的影响情况。[结果]1991—2020年北京市生态环境质量总体以减小趋势为主。其中,林地区域生态环境质量表现为“先增加—减小—增加”趋势,灌木区域生态环境质量呈“增加—减小—增加—减小”趋势,草地、耕地、湿地和不透水面区域生态环境质量呈“减小—增加—减小”趋势,荒地区域生态环境质量一直呈“减小”趋势。不透水面区域生态环境质量主要受到干度的负影响和湿度的正影响较大,绿度和热度主要通过影响湿度和干度对其产生影响;草地、荒地和灌木区域生态环境质量主要受到热度负影响和绿度、湿度和干度正影响;耕地区域生态环境质量主要受到干度和热度的负影响;林地区域生态环境质量受到湿度、干度、热度和绿度的影响均较大;湿地区域生态环境质量受到热度、绿度和湿度的正影响大于干度的负影响。[结论]北京市在生态环境维持与治理方面政策的大方向是有效的,绝大部分区域生态环境质量都在提升,少部分地区略有降低,应有针对性地进行政策调整,改善生态环境质量,但后期仍需要进一步规范化北京市土地覆盖并进一步加强自然灾害的防护策略。[Objective]The aim of this study is to evaluate the ecological environment status of a region,which is of great practical significance for promoting urban construction and economic development,achieving ecological environment protection and sustainable economic and social development in Beijing.[Methods]The remote sensing ecological index(RSEI)coupled with the characteristics of regional greenness,humidity,dryness,and heat was used to explore the temporal and spatial dynamics of eco-environmental quality in Beijing from 1990 to 2020.Sen trend analysis,Manna-Kendall mutation point test,Hurst method,multiple regression,and structural equation model were employed to explore the impact of different environmental factors on the ecological environment quality of Beijing.[Results](1)From 1991 to 2020,the overall ecological environment quality in Beijing showed a decreasing trend.Among them,the ecological environment quality of forest areas showed a trend of‘increasing decreasing increasing’,while the ecological environment quality of shrub areas showed a trend of‘increasing decreasing increasing decreasing’.The ecological environment quality of grasslands,farmland,wetlands,and impermeable areas showed a trend of‘decreasing increasing decreasing’,while the ecological environment quality of wasteland areas had always shown a trend of‘decreasing’.(2)The ecological environment quality of impermeable areas was mainly affected by the negative impact of dryness and the positive impact of humidity.Greenness and heat mainly affected them by affecting humidity and dryness.The ecological environment quality of grassland,wasteland,and shrub areas was mainly negatively affected by heat and positively affected by greenness,humidity,and dryness.The ecological environment quality of cultivated land areas was mainly negatively affected by dryness and heat.The ecological environment quality of forest areas was greatly affected by humidity,dryness,heat,and greenness.The ecological environment quality of wetland areas was p
