煤炭城市的生态环境质量研究与评价

EVALUATION AND COMPARATIVE RESEARCH OF ECOLOGICAL ENVIRONMENT QUALITY OF COAL CITIES

本文通过构建生态环境质量的评价指标体系,采用多元统计方法中的因子分析方法,对2003年30个煤炭城市的生态环境质量进行了评价分析,得出了各主成分以及综合水平得分,然后根据煤炭城市的生产总值、原煤产量和空间分布等特征进行分类研究,结果表明:生产总值和原煤产量较高的煤炭城市,生态环境质量平均水平要高于中等以下的城市,但是它们之间不具有明显的正相关性。另外,东部地区质量水平要好于其他地区。

The paper uses factor analysis in the multiple statistical methods, and analyzes ecological environment quality of 30 coal cities in 2003, then constructs a system of evaluation indicators of the quality of the ecological environment, arrives at a comprehensive level of the main components and their scores at last. Then, studies in classification in accordance with the gross product of the coal cities, coal production and the feature of the spatial distribution, the conclusion is got that the ecological environment quality of the cities with higher gross product and coal production is higher than the average level of middle and lower city,ies with higher gross product and coal production is higher than the average level of middle and lower city, However, they don＇t have the obvious relevance. Meanwhile, the quality of the eastern regions has a better advantage over the others.
