摘　　要：为探讨沈阳市棋盘山水库湿地保护地近30年生态系统演变规律,文章运用3S技术和景观格局指数,分析了保护地1986~2015年生态系统时空变化及景观格局演变特征。结果表明:1986~2015年间,由于人类活动的干扰,保护地景观破碎度和空间异质性不断增加,水库周边建设用地围绕水库向南部、北部不断扩张,不利于生态系统服务功能的保护和提升,但总体上看,2000~2015年人类活动强度低于1986~2000年,说明该时期生态保护工作取得一定成效。为提升保护地景观质量和生态系统服务功能,提出了保护地生态系统服务可持续管理对策。In this paper, to explore the patterns of ecosystem revolution of Qipan Mountain Reservoir Wetland Reserve in the past 30 years, 3S technology and landscape mosaic indicators were applied to analyze the spatial-temporal change and evolutionary process of its landscape mosaic structure from 1985 to 2015. The results showed that due to the interference of human activities, the landscape fragmentation and spatial heterogeneity of the reserve significantly increased. The construction land around the reservoir expanding to the south and north, unfavorable for protection and improvement of the ecosystem services. However, generally the intensity of human activities from 2000 to 2015 was lower than that from 1986 to 2000, indicating that ecological protection work achieved certain results during that period. Finally, countermeasures of sustainable management were put forward to improve the landscape quality and ecosystem services of the reserve.
