摘要
在研究煤田火区对自然-社会经济系统影响的基础上,提出了煤田火区环境影响综合评价指标体系的构建思路,建立了煤田火区环境影响评价的一般性指标体系,包括5级32个指标。以内蒙古乌达煤田火区为实例,论述了煤火环境影响综合评价的实施过程。根据煤田火区特征,在一般指标体系框架内确定了23个评价指标,采用层次分析法与综合指数法相结合,建立了火区环境影响综合评价公式。评价结果表明,乌达煤田火区对环境的影响为较严重水平,与定性分析结果相符。
Based on study of the influence of the coalfield fires on the nature-socioeconomic system,the design strategy of the index system for comprehensively assessing the environmental impact of coal fires is brought forward,and the general index system is established which may be divided into 5 grades and 32 indexes.The fires in Wuda coalfield of Inner Mongolia is taken as an example to show the application of comprehensive assessment of environmental impact of coalfield fires.According to the coal-fire characters of Wuda coalfield,23 indexes for the environmental assessment is selected.Finally,the comprehensive assessment formula is set up in terms of analytic hierarchy method and complex index method.The assessment results indicate that the environmental impact of coal fires in Wuda coalfield is in the rather serious level,which is consistent with that of qualitative analysis.
