摘要
云南省１９９０－１９９６年１７个城镇的ＴＳＰ污染水平一直在０２０ｍｇ／ｍ３左右波动，比较平稳。将年平均浓度值与超标率相比较，历年来ＴＳＰ的污染程度变化不大，但污染面有逐年扩大的趋势。因此，为提高空气质量达标率，必须加强管理和技术方面的措施。
The TSP of 17 cities and towns in Yunnan from 1990 to 1996 fluctuates at 020mg/m3.According to the comparison of the annual average density and the rate of over standard,the change of pollution of TSP is little.However the pollution area has a tendency of gradually spreading.Management and the technical measure should be strengthened so as to raise the air quality meeting therequirement of the standard.
