摘　　要：以冀东平原区域的河北滦县两期土地利用现状图为基础,结合GIS及Fragstats软件,对1996年、2009年景观格局及其生态服务价值进行分析。结果表明:13a来,滦县农田景观优势度降低,建设地景观优势度增高,破碎度增大,景观形状趋于简单。两期比较,总生态服务价值(ESV)减少了1 336.19万元,其中建设地景观扩展是生态服务价值减少的最主要因素。生态服务价值变化同农业景观格局演化之间紧密相关,其中景观斑块面积、景观斑块种类、斑块数量及破碎度等指数的变化都会引起区域生态服务价值波动。可通过保护区域林地、园地、水域等关键景观类型,增加有效网络面积和连通性,减少干扰以降低斑块破碎度等措施来增强区域的生态系统服务价值,更好地支撑和保证区域的可持续发展。Based on the map regarding the status quo of land use in its two different periods, combining with GIS and Fragstats software, this paper analyzed landscape patterns and ecosystem service values （ESV） of Luan County in 1996 and 2009. The results showed that its farmland landscape dominance index reduced, but its landscape dominance of construction land raised, landscape fragmentation index increased （aggravated）, and landscape shape tended to be simple during the 13 years between 1996 and 2009. The total ecological service value decreased by 1. 336）〈 107 Yuan from 1996 to 2009, with construction landscape expansion the biggest single component. Moreover, the change of ecological service value and the evolution of agricultural landscape pattern were closely related, the variations of indices in patch area, patch type, patch number and fragmentation would cause the fluctuations of regional ecological service value. Therefore, it would be important to take measures including protection of the critical landscape types such as shrub, grassland, and woodland, increase of the patch size and connectivity, and reducution of the frequency and severity of disturbances to avoid further fragmentation, so as to ensure the ESV growth and the sustainable development of the study area.
