气田开发建设项目环境影响后评价研析

The Preliminary Study on Environmental Impact Post-assessment of Gas Field Development Project

环境影响后评价作为环境影响评价的延伸,是提高环境影响评价有效性、指导开展环境保护的有力手段。在介绍气田开发建设项目环境影响特点、环境影响后评价必要性及意义的基础上,从污染影响、生态影响两个方面分析了气田开发建设项目环境影响后评价的内容,构建了一套后评价指标体系,提出了对比法、资料收集法、现场调查法及“3S”技术方法作为气田开发建设项目环境影响后评价的方法,以期为开展气田开发建设项目环境影响后评价提供参考。

Environmental impact post-assessment is extension of environmental impact assessment ( EIA ), and it is a powerful means to improve the effectiveness of EIA and guide to carry out environmental protection. Based on the introduction of the environmental impact characteristics, the necessity and related significance of environmental impact post-assessment for gas field development project, the contents of environmental impact post-assessment of gas field development project are analyzed from three aspects of the pollution impact, ecological impact and social impact. Finally, a set of index system of environmental impact post-assessment was constructed, comparative method, data collection method, spot investigative method and 3S technology method were put forward as the post-assessment method, in order to give a reference for environmental impact post-assessment for gas field development project.
