摘要
国家大型煤电基地的规划建设是《中国国民经济和社会发展"十二五"规划纲要》中的重要内容,也是我国未来能源发展战略的重要举措。随着社会经济的不断发展,对人类活动生态效应的评估也越来越受到关注,对国家大型煤电基地生态效应的评估是确保煤电基地区域可持续发展的重要步骤。我国煤电基地多分布在北部干旱半干旱的生态脆弱区,区域生态环境直接影响到我国京津唐、东北城市群、华北东北两个主要粮食基地的生态安全,乃至直接影响到国家生态安全。因此,对国家大型煤电基地生态效应进行科学评估至关重要。基于DPSIR(驱动力Driving force—压力Pressure—状态State—影响Impact—响应Response)概念模型,以内蒙古锡林郭勒盟煤电基地为主要研究区域,从社会经济、资源能源、生态环境三个相关系统中梳理出43个评估指标,构建了国家大型煤电基地生态效应评估指标体系,以期科学评估国家大型煤电基地建设运营过程中的生态效应。
Planning and construction of the national large-scale coal-fired power bases are one important department of Twelfth Five-Year Plan., and it is also an important measure of development strategy of China＇s future energy.With the development of social economy, people pay more attention on the assessment of ecological effects on human activities. So the assessment of ecological effects on the national large-scale coal-fired power base is an important way ensuring the regional sustainable development of the national large-scale coal-fired power base. The national large-scale coal-fired power bases are always distributed in arid and semi-arid regions in the north of China. The regional ecological environment direct impact on ecological safety of Beijing, Tianjin, Northeast urban agglomeration, and two of major grain production bases, even the nation. Therefore, it is essential to evaluate the ecological effects of national large-scale coal-fired power base scientifically. Based on the DPSIR（Driving force-Pressure-State-Impact-Response） conceptual model, we built an evaluation system of the ecological effects, in the Xilin Gol League coal-fired power base in Inner Mongolia. The evaluation system is made of three parts of social economics, resources and energy, ecological environment. There are 43 indicators in total to give a scientific assessment of ecological effects of national large-scale coal-fired power bases during construction and operation. By building the comprehensive evaluation index system based on the DPSIR conceptual model, the author recognized the key ecological efficiency factors of large-scale coal-fired power bases and sensitivity indicators. These results roundly reflect the dynamic effect between large-scale coal-fired power bases and their eco-environment. And also the result could help people understand the system impact of the large-scale coal-fired power bases. From the point of systems analysis, based on the DPSIR conceptual model, the author divided the comprehensive evaluation index s
