基于土地利用变化的福建省自然保护区生态系统服务价值研究

Ecosystem Service Value of Nature Reserves in Fujian Province Based on Land Use Change

以福建省自然保护区为例,依据2000年、2005年和2010年福建省土地利用数据,利用ArcGIS软件分析各类型土地利用的面积及其变化特点,并参照谢高地的生态系统服务价值计算方法,分析了福建省自然保护区内土地利用变化与生态系统服务价值之间的关系。结果表明:(1)2000—2010年,土地利用发生了较大的变化,各类型之间转换比较频繁,且林地面积逐渐在减少,园地和建设用地面积逐渐在增加,其他土地类型面积先增加后减少;(2)2000—2010年,林地主要转变为园地和耕地,园地主要由林地和草地转换而来,林地为自然保护区最主要的土地利用类型;(3)2000—2010年,自然保护区生态系统服务价值逐渐减少,且土地利用变化与各类型的生态系统服务价值变化相对一致。

Based on land use data in 2000,2005 and 2010,land use area and its variation characteristics of nature reserves in ArcGIS were investigated in Fujian Province.The relationship between land use change and ecosystem service value in Fujian nature reserve was analyzed with Xie Gaodi＇s method.Result shows that：（1）The land use change a lot,the conversion of land use types is frequent from 2000 to 2010.And the area of forest land decrease gradually,the garden land and construction land increase.（2）From 2000 to 2010,the forest land was transformed into garden and cultivated land,and the land was mainly converted from forest land and grassland.Forest land is the main land use type in nature reserve.（3）The value of ecosystem services in nature reserve gradually reduce,and the change of land use and ecosystem services value of various types of ecosystem service value change is relatively consistent from^2000 to 2010.
