摘　　要：以宁县的土地利用总体规划修编为例,并结合宁县的实际情况建立了一套环境影响识别的指标体系,在此基础上,利用改进熵值法确定各指标的权重,通过DPSIR获得环境影响综合评价值.结果表明,2001—2008年,宁县土地利用总体规划环境影响综合评价值增加了0.026 3,变化幅度较小;宁县土地利用总体规划对整体环境具有正面的环境影响.In this paper taking the revision of the general land use planning of Ningxian County as example,together with local practical situation,a series of environmental impact identification indices is set up.The weight of each index is determined by improved entropy method,and then furthers the comprehensive value of environmental impact is calculated by DPSIR.The results indicate that the comprehensive value of land use planning environmental impact has increased 0.026 3from 2001 to 2008,but the amplitude has little changed.The land use planning have positive implications for understanding environmental variability in Ningxian County.
