先导区土地利用变化及生态服务价值研究

Research on Land Use Change and Ecosystem Services Value of Xiandao District

依据景观生态学和生态服务价值原理,利用先导区2008～2013年土地利用变更数据和经济社会数据,计算土地利用结构指数和生态服务价值,分析土地利用结构、GDP与生态服务价值之间的关系。研究结果表明:1)2008～2013年先导区除建设用地和其他农用地面积呈增长趋势外,其余地类面积均不断减少,其中降幅最大的是水域,下降了3.16%;2)先导区土地利用多样化指数、优势度指数呈现小幅增大趋势,多样性指数和均匀度指数则呈现小幅下降趋势;3)先导区土地利用生态服务价值呈逐年递增的趋势,同时各地类的生态服务价值也都有不同程度的增长;4)土地利用结构的多样化和均匀化有利于提高先导区生态服务价值;5)先导区经济发展与生态服务价值之间处于正向协调状态,且生态服务价值的增长速度小于GDP的增长速度,两型社会建设成效初步显现。

Based on the theory of landscape ecology and ecosystem services value, this paper used land changed data and economic-social data of Xiandao District from 2008 to 2013, calculated land use structure indexes and ecosystem services value, analyzed the relationship among land use structure,GDP and ecosystem services value. Research results indicated: 1) Except the area of construction land and other crop land increased from 2008～2013, the area of other land use type all decreased, and the area of water body decreased most, which was 3.16%; 2) Land-use diversity index and dominance degree index increased while evenness degree index decreased; 3) Land use ecosystem services value of Xiandao District increased year by year, meantime ecosystem services value of all land use types increased in different levels; 4) Diversification and homogenization of land use structure benefited ecosystem services value of Xiandao District; 5)Economic development and ecosystem services value in Xiandao District was in a state of positive coordination, and the growth rate of ecosystem services value was lower than that of GDP, the construction of two-style society appeared certain effect.
