重庆市生态环境质量综合评价研究

Integrated Evaluation on Ecological Environment Level in Chongqing

从城市生态学的角度出发,研究了重庆市生态环境质量综合评价的方法.首先利用因子分析的方法,针对重庆市的生态环境构建了基于生态结构、生态功能和生态协调度的三级影响指标体系;接着利用层次分析的方法对各级指标进行权重计算,在此基础上对重庆市的生态环境质量进行了综合评价;最后通过数据仿真可以看出重庆市1990年到2004年的城市生态环境量化评价标准由中下水平,上升至接近良好水平,总体呈现良好的发展趋势.实验结论表明所构建的指标体系能较真实地反映重庆市的生态环境质量,具有良好的适用性.

The paper researched the problem for integrated evaluation of ecological environment level about Chongqing based on urban ecology. First of all, three - level impacting Indicator systems for Chongqing ecology environment, which consisted of ecological structure, ecological function and ecological harmony, have been established by using factor analysis method; Secondly, their power indexes were computed using AHP and integrated evaluation of Chongqing ecology environment quality was derived; Finally, Then, the data simulation showed that Choing environment condition was inoreasingly better,which becomes fine from moderate to inferior level, at transit of 1994 to 2004. Simulative examples show the index set constructed in the paper may really affect the environment quality of Chongqing, thus , they were provided with the better applicability.
