基于层次分析法的基本原理，构建了水库对河流生态系统服务功能影响的生态足迹评价指标体系，运用 AHP 确定各个评价指标权重。以大伙房水库为例，进行了水库对河流生态系统服务功能影响的综合评价，最后应用生态足迹评价模型定量地核算了大伙房水库 4 项生态供给足迹和 3 项生态需求足迹。

 On the basis of the fundamental principle of analytical hierarchy process(AHP), first of all, an intex assessment system on ecological footprint of the impact of a reservoir on river ecological service functions is established, and then, the weights of every index are determined by AHP. The Danhuofan Reservoir in Fushun is taken as an illustration, the aggregate assessment on the influence of the reservoir on river ecological service functions is carried out. At the end, the mentioned above model is applied to quantitatively calculate four-item ecological footprints and 3-item ecological demands of the Danhuofan Reservoir.
