本研究基于生态系统服务价值理论对天门市2006～2020年土地利用总体规划方案进行环境影响评价。鉴于谢高地等建立的我国生态系统服务功能价值评估体系不适于中小尺度的区域研究，本文根据天门市实际情况修正各土地生态系统单位面积生态服务价值系数，采用Costanza生态系统服务价值计算公式结合ARCGIS 9.3技术得出2005～2020年天门市生态系统服务价值的变化：生态服务总价值量增加7.75亿元；生态服务价值结构变化较小，食物生产、气体调节和保持土壤这三项价值有所减少；空间分布变化主要表现为中心城区城镇生态系统的扩大和周围工矿生态系统的减少。评价结果对天门市生态环境建设具有重要的现实意义。

Based on the theory of ecosystem services value (ESV), this paper is to evaluate environmental impact of the overall land use planning in Tianmen City from 2006 to 2020. Because the equivalent value per unit area of ecosystem services in China pro-posed by XieGaodiis inapplicable to small-scale regional study, so in this paper the correlation coefficient is corrected by the actual situation of Tianmen City and using the calculating equation of ecosystem service values proposed by Costanza, with the technical support of ArcGIS, the following result and conclusion which is significant to eco-environment construction of Tianmen City could be obtained: the total value of ecosystem services increase 7.75 billion yuan; There are some changes in the structure of ecosys-tem services value like some function are weakend, for example, food production and gas regulation and soil formation; Its variation in spacemainlymarked bythe expansion of urban ecosystem and the reduction of industrial ecosystemaround cities.
