摘　　要：寿县是淮河流域和安徽省生态环境重点保护县区,对寿县定期进行生态环境调查可为流域生态保护管理与决策提供高效支撑与服务。融合多源遥感和生态环境数据,对2010—2015年寿县生态系统格局与构成、生态系统质量进行调查分析,综合评价区域生态状况。结果表明:(1)寿县自然景观类型优势度提高。裸土面积向湿地和耕地转移;林地、河流、湖泊和水库/坑塘等自然生态类型所占比例均有所提升。(2)寿县生态系统格局异质性提高。景观整体的斑块密度、边缘密度提升,平均斑块面积下降,生态系统中异质斑块之间物质、能量、物种及其他信息交换的潜力及相互影响的强度增加。(3)寿县林地、耕地和湿地的生物量显著提升,生态状况向好的趋势发展。Shou county is a key ecological environment protection county in Huai River Basin and Anhui Province.Regular ecological environment survey in Shou county can provide efficient support and service for watershed ecological protection management and decision-making.By integrating multi-source remote sensing and ecological environment data,the ecological system pattern,composition and quality of Shou county from 2010 to 2015 were investigated and analyzed,and the regional ecological status was comprehensively evaluated.The results indicated that:(1)The dominance of natural landscape type in Shou county has increased.The bare soil area has been transferred to wetlands and croplands,and the proportion of natural ecological types such as forests,rivers,lakes,reservoirs/pit-ponds has increased.(2)The heterogeneity of ecological pattern has improved.The patch density and edge density of landscape has increased,the average patch area has decreased,and the potential for the exchange of substances,energy,species and other information and the strength of interactions between heterogeneous patches in ecosystem has increased.(3)The biomass of forest,cropland and wetland has improved significantly in Shou county,and the ecological situation has developed towards a good trend.
