摘　　要：提出一种基于模糊聚类分析中传递闭包法的环境质量评价分析方法.介绍了传递闭包算法,并以西南5个城市作为样本,选择4个环境因子,采用传递闭包法进行城市分类,分类的结果与5城市实际情况相符.成都、昆明环境质量评价为好,贵阳、拉萨为较好.5城市的环境质量中空气质量和饮用水环境的质量好,但出境断面水质和噪声水平有待改进.A new environment appraisal analysis method based on the transitive closure algorithm which is commonly used in the fuzzy clustering analysis was proposed. Four different environment factors were selected for 5 cities in southwestern area to make a cities classification by using transitive closure method （TCM）. The results tally with 5 cities＇ actual situations. The environment quality of Chengdu and Kuenming wins a ＂good＂ appraisal, while that of Guiyang and Lasa gains a ＂rather good＂ appraisal. 5 cities all have good quality of air and drinking water, but the exit fracture surface water quality and the noise level should be further improved.
