长江上游生态脆弱区土地利用结构及生态服务价值变化响应——以甘肃省陇南市为例
Responses of Ecologically Fragile Areas of Yangtze River of Ecological Service Value to Land Use Change——A Case Study of Longnan City, Gansu Province
摘要
Abstract
By using the data of land use survey of Longnan City from 2003 to 2008 and the methods of structural quantitative analysis of landscape ecology, this paper calculated the land use heterogeneity and ecological service value and analyzed the changes of land use structure and ecological service value as well as their relationship. The results showed that the indices of both diversity and evenness of land use increased but the dominance index of land use decreased. The ecological service value of forest land were highest in Longnan City, and the total ecological service value of land use increased from 2003 to 2008. There were linear correlations between the structure and ecological service value of land use ecosystem.关键词
