摘要
计算得到2013年安徽省单位面积生态系统服务功能价值表,估算2009~2013年庐江县土地生态系统服务价值,并分析土地利用/覆被变化对其生态服务价值的影响。研究表明:(1)土地利用/土地覆被变化主要表现为除耕地以外的非建设用地的减少,而建设占用是这种减少的最主要原因,尤以2012年度为甚。(2)生态系统服务总价值逐年递减,总减少量约为5490万元,年均减少约1373万元。其下降主因是水域、湿地、林地的减少。(3)生态系统服务功能价值主要集中在水域、耕地和林地之中。
On the base of calculating out the Coefficient value of ecosystem services of Anhui in 2013, We estimated Lujiang Coun ty's value of Land Services Ecosystem from 2009 to 2013, and studied how the land use/cover change have affected the value of ecosystem services. Studies have shown that: (1) Reducing of lots of non-construction land, except for farmland, was the main mani- festations of LUCC; and the expansion of construction land is the main reason for this change, especially in 2012; (2) Lujiang's val- ue of ecosystem services were decreasing, with an average annual deerease of 13.73 million yuan, and its total reduction is 54.9 million yuan in these 5 years. This kind of decrease were mainly due to the decline of territorial waters, wetlands and forest; (3) The value of ecosystem services of Lujiang eounty is mainly concentrated in the waters, farmland and woodland.
