中文摘要 研究生态系统服务价值(ESV)对城市景观格局演变的响应变化,可为城市生态保护建设和绿色生态发展提供一定科学依据。文章基于湖北省石首市1986—2016年遥感影像,利用ENVI解译景观类型,运用土地利用转移矩阵、景观格局指数和ESV评价方法,分析生态系统服务价值与景观格局演变的相关性及其响应变化。结果表明:1)石首景观格局变化剧烈,景观破碎度升高,异质性增强,ESV总量先下降、后上升;2)草地和林地是优势景观,主导ESV上升,水系支撑ESV,水文调节是主要生态系统服务类型;3)城市生态系统服务价值变化对景观格局演变的响应机制明显,生态系统服务价值随着景观格局连通度增强、异质性提升、斑块面积扩大和密度降低而增长。

英文摘要 The study of the response of ecosystem service value (ESV) to the evolution of urban landscape pattern can provide science basis for urban ecological protection and green ecological development. Based on remote sensing images from 1986 to 2016 in Shishou, Hubei Province, the paper uses ENVI to interpret landscape types, and adopts land use transition matrix, landscape pattern index and ESV evaluation methods, to analyze the correlation between ecosystem service value and landscape pattern evolution and its response. The results show that: 1) The landscape pattern in Shishou changes drastically, manifested by increased landscape fragmentation and the heterogeneity increases, and first decreases and then increases of total ESV amount; 2) Grassland and forest are dominant landscapes, with the rise of leading ESV which is supported by water system, and the hydrology regulation is the main type of ecosystem service; and 3) The response of urban ecosystem service value changes to the evolution of landscape pattern is obvious, and ecosystem service value increases with the increase of landscape pattern connectivity and heterogeneity, patch area expansion and density reduction.
