| 摘 要： | 分析了主成份子集合选择法的应用过程,指出该方法只考虑了各测点的污染随机变化信息.而忽略了各测点的污染水平信息;用该方法所得到的优化点集不能正确地反映地区大气污染水平.因而主成份子集合选择法不宜应用于大气例行监测的优化布点研究中.

| Abstract: | This paper analyzes the application of Principal Component Subset Selection, and suggests that this method neglects the information of pollution levels in monitoring sites and not reflect the regional pollution level correctly. Therefore, the Principal Component Subset Selection should not be applied to the research for the optimal monitoring sites of atmospheric environmental quality. |
