摘要
采用系统分析的方法,围绕社会经济压力、水体污染负荷以及水体环境状态3个方面,建立社会经济活动对太湖流域生态影响的评价指标体系,利用层次分析法计算各指标因子的权重。根据太湖流域2005和2006年的相关数据,以MATLAB为工具,运用模糊模式识别方法进行流域生态综合评价,分析社会经济活动对太湖流域的生态影响。研究结果表明,太湖流域的社会经济活动对湖泊生态的影响较大,除了点源污染以外,面源污染也是太湖流域生态环境问题的重要根源。
By means of system analysis, an index system, centering around socio-economic pressure, water pollution load, and water environmental status, is established for evaluation of ecological impact of the socio-economic activities on the Taihu Basin. Weights of the indices of the system were computed, using AHP （analytic hierarchy process）. And based on available data related to the Taihu Basin in 2005 and 2006, comprehensive evaluation of the ecology of the basin was performed with the aid of MATLAB and the approach of fuzzy pattern recognition. And finally, ecological impact of the socio-economic activities on the Taihu Basin was analyzed. Results show that the impact was enormous. Besides pointsource pollution, non-point source pollution is one of the root causes of the ecological problems in the region.
