摘要:
内蒙古锡林郭勒盟国家大型煤电基地的建设,对我国华北和华东区域能源安全具有重要的作用。但随着锡盟大型煤电基地的开发,其对锡林郭勒盟这一具有重要生态屏障功能的典型草原区的生态环境造成不利影响。通过对区域生态敏感性、生态弹性及生态压力的系统研究,建立了基于生态敏感性、生态弹性及生态压力的生态脆弱性评价模型,对该区域生态脆弱性进行了评价。结果表明,锡盟地区总体生态环境质量较好,但呈现由东北向西南递减的特征。研究为锡林郭勒盟国家大型煤电基地的开发建设,区域协调发展与生态环境保护提供理论支持。
Abstract:
The construction of the coal-electricity base area in Xilinguole League, Inner Mongolia, plays an important role in the regional energy security in northern and eastern China, and in the improvement of the regional ecological environment. In contrast, the development of the coal-electricity base also has adverse effects on the typical grassland region, which is an important ecological barrier. This study investigated the regional ecological sensitivity, ecological elasticity, and ecological pressure of the coal-electricity base; a model of regional ecological fragility was constructed on the basis of the three indexes. An evaluation of the regional ecological fragility was performed. The results demonstrated that the ecological environment quality of Xilinguole League is generally good; however, it was found to worsen from the northeast to the southwest. This study of Xilinguole league has positive implications for the development and construction of a large national coal-electricity base, and provides theoretical support to coordinated development and environment protection in the region.
