摘要
文章结合对苏锡常进行的生态环境质量评价,系统地探讨了环境污染与社会经济等人文因子对区域生态环境质量的影响模式,结果表明:当环境污染分指数(经过了正相关处理,其值越大表明区域受到的环境污染影响程度越小)、社会经济分指数出现相同的变化趋势,这时生态环境质量综合指数也出现相应的变化趋势;当环境污染分指数、社会经济分指数出现相反的变化趋势,这时如果环境污染分指数值与社会经济分指数值的年变化率值之和大于0,则生态环境质量综合指数值的年变化率为正,即生态环境质量出现相对地提高,反之亦反。
According to evaluations of the eco_environmental qualities of Suzhou city, Wuxi city and Changzhou city, the influence of human factors to regional eco_evironmental quality is systematically discussed with the method of AHP. The conclusions are showed as follows: 1) When index of environmental pollution (its value is larger, the contaminative degree of region is smaller by commutation of positive correlation) and index of social economy have the same trends, integrated indexes of eco_environmental quality also have corresponding trends. 2) When index of environmental pollution and index of social economy have opposite trends, annual variable rate of eco_environmental quality is positive, namely eco_evironmental quality would corresponding improve, if the summation of annual variable rates of index of environmental pollution and index of social economy is larger than zero. Whereas its quality would deteriorate.
