以河北省大清河水系阜平流域为研究对象,利用景观格局指数分析法、服务功能价值量评价法及相关分析等方法,研究了1985—2015年该区域土地利用景观格局及生态系统服务价值变化规律,分析了服务功能与土地利用景观格局之间的相互关系,探讨了生态服务功能对土地利用景观格局变化的响应过程。结果表明:1)研究区近30年城市、林业、农业、水域景观呈增加趋势,荒漠、草地景观呈减少趋势。总体上表现为斑块数量减少,平均斑块面积增大,各景观类型连通性增强,景观结构愈加稳定。2)研究区生态服务总价值在2000年最高(58.08亿元),2000年之前呈增加趋势,2000年之后呈减少趋势。林地服务价值贡献率最大,其次为农田和草地;单项服务价值中维持生物多样性与保持土壤服务贡献率最大,其次为气体调节和气候调节。3)生态系统总服务价值与斑块密度、景观形状指数、面积加权平均形状指标、面积加权平均分维数、平均斑块面积、聚集度均有较强的相关性。

We,taking Fuping watershed of the Daqing River as a research object,investigated the changes of landscape pattern and ecosystem services over a period of time from 1985 to 2015,and analyzed the relationship between them.The results show that the landscape pattern of the study area changed significantly during the investigation period,the urban landscape,forest landscape,agricultural landscape and water landscape area changed positively,and the unused land landscape and grassland landscape changed negatively.The mean patch area increased,the connectivity of each landscape type is better,and the landscape structure became more stable.The value of ecosystem services in the study area increased before 2000,and decreased after 2000,the forest land made the greatest contribution to the total ecosystem value of the study area,followed by cultivated land and grassland.In the value of single service,the contribution rate of soil conservation was the largest,followed by biodiversity maintenance,air regulation and climate regulation.There is a good correlation between ecosystem services and patch density,landscape shape index,mean patch area,area weighted mean shape index,area weighted mean fractal dimension and aggregation degree at the landscape level.
