摘　　要：为有效评估“十三五”期间安徽省生态环境状况变化,制定生态保护治理决策提供科学依据,以安徽省行政区域为研究对象,选用针对安徽省2015—2020年的植被覆盖度、叶面积指数和总初级生产力的MODIS数据产品,以及两个典型生态区夏季的Landsat 8 OLI遥感影像反演的植被生态参数遥感产品,构建生态系统质量指数模型,分析安徽省生态系统质量动态变化及其主要影响因素。结果表明:2020年,安徽省生态系统质量指数均值为62.27,评定等级为良,且各行政区生态系统质量等级均为中级以上,黄山市评价等级为优。2015—2020年,安徽省生态系统质量总体呈提升的趋势,其中,蚌埠市生态系统质量明显提升,阜阳市、淮南市和马鞍山市生态系统质量明显下降;5个生态功能区中,沿长江平原生态区生态系统质量明显下降,皖西大别山生态区生态系统质量明显提升;安徽沿江经济带和皖南山地丘陵区典型生态区生态系统质量下降的区域主要集中在长江芜湖段和宿松段两岸、皖南山区的西南部区域。Taking the administrative region of Anhui Province as the research object, the MODIS data products based on the vegetation coverage, leaf area index and total primary productivity of Anhui Province during 2015-2020 and the remote sensing products based on Landsat 8 OLI remote sensing image inversion of vegetation ecological parameters in summer of two typical ecological regions were selected to build the ecosystem quality index model. The dynamic change of ecosystem quality and its main influencing factors in Anhui Province were analyzed. The results showed that in 2020, the average value of ecosystem quality index in Anhui Province was 62.27, which was rated as good, and the ecosystem quality level of each administrative region was above intermediate, and Huangshan City was rated as excellent. From 2015 to 2020, the ecosystem quality of Anhui Province showed an overall trend of improvement, among which Bengbu City significantly improved, while Fuyang City, Huainan City and Maanshan City significantly decreased. In the five ecological functional zones, the quality of ecosystem along the Yangtze River Plain decreased obviously, while the quality of ecosystem in the Dabie Mountain ecological zone in western Anhui improved obviously. The decline of ecosystem quality in the economic belt along the Yangtze River in Anhui Province and the typical ecological areas in the mountainous and hilly areas in southern Anhui Province is mainly concentrated in the Wuhu and Susong Sections of the Yangtze River and in the southwest of the mountainous areas in southern Anhui Province.
