| 摘 要： | 文章在商洛市1999-2007年土地利用变更数据及第二次土地利用调查数据库的基础上,根据Costanza的生态服务价值核算体系估算商洛市生态服务价值,运用GIS软件并结合生态敏感度分区图对商洛市生态服务价值进行了空间分析,结果表明:1999-2007年,生态服务价值共增长了9.3亿元,商州区、洛南县属于生态服务价值增长滞后区,其余各县属于生态服务价值增长贡献区;商州区、丹凤县、洛南县三区县交界处应为重点生态建设区域;镇安县、商南县、山阳县生态建设意义重大。

| Abstract: | This study is based on the 1999 -2007 change of land utilization data and the second update of land use survey. According to the Costanza＇ s ecosystem service value theory, this paper conducted special analysis on the ecological service value of Shangluo using GIS and combined with ecological sensitive subarea map. The result shows that the value of ecological services have raised to 930 million yuan from 1999 to 2007, while Shangzhou, Luonan lagged behind and the rest areas are contributing zones of ecological service value. The borders of Shangzhou, Danfeng, Luonan districts are key areas of ecological construction. The ecological construction of Zhen＇ an, Shangnan and Shanyang is of great significance. |
