基于我国页岩气开发现状，借鉴美国页岩气开发的成功经验，对页岩气开发环境影响因素进行分析，建立了页岩气开发环境影响评价指标体系及具体的评价准则；同时引入层次分析法对相关因素进行目标、准则、方案等多层次多目标的划分，建立了页岩气开发综合环境影响评价模型。最后将评价体系与评价模型应用到实际案例中，得到的评价结果与实际情况基本符合。研究成果为页岩气开发项目的综合环境评价提供了很好的理论依据。

Based on the present situation of shale gas development in China and the successful experiences of shale gas development in the United States, the environmental impact factors that are caused by the development of shale gas are analyzed in this paper. The evaluation index system for environmental impact from shale gas development and the specific evaluation criteria are established respectively. The analytic hierarchy process is used to classify the related factors by goal, criterion and scheme, and the evaluation model of comprehensive environmental impact of shale gas development is established. Finally, the evaluation system and the evaluation model are both applied to the actual cases, and the evaluation results gained meet basically with the actual situation. This research provides with a good theoretical basis for the comprehensive environmental impact evaluation for the development of shale gas projects.
