基于系统聚类分析的西部地区环境污染程度评价

The environmental pollution degree in West China assessed by hierachical cluster analysis

随着社会经济的不断发展,环境污染问题在西部地区经济发展中越来越凸显出来,不同省区受到不同程度的影响.同时,不同地区的环境污染问题有一定的相似性.应用系统聚类分析方法,通过提炼选取11类指标,对西部地区12省区环境污染程度的距离相似情况进行了评价.结果表明:贵州、甘肃、广西、云南、重庆和陕西等省区的距离相似归为第一类聚类;内蒙古和四川归为第二类聚类;西藏、宁夏和青海等省区的距离相似属于第三类聚类;新疆归为第四类聚类.要处理好生态系统和社会经济发展之间的关系,需要对二者进行协调,并坚持走可持续发展的道路.

Environmental pollution is more and more highlighted in economic development in West China,with different influences in different provinces,as well as,different provinces affected by environmental problems of similar degree. Eleven indicators are selected to assess the environmental pollution degree of the twelve provinces in West China with the method of hierachical cluster analysis. As a result,four clusters are revealed,i. e.,the first cluster（ involving Guizhou,Gansu,Yunnan,Shaanxi,Guangxi and Chongqing）,the second cluster（ involving Inner Mongolia and Sichuan）,the third cluster（ involving Xizang（ Tibet）,Ningxia and Qinghai）and fourth cluster（ Xinjiang）. Therefore,to deal with the relationship between the ecological system and economic development,it is needed to coordinate with the both and to insist sustainable development.
