摘要: 采用灰色聚类法与综合污染指数法对辽宁省东部山区3个县区土壤污染现状进行了调查和评价.结果表明,岫岩县土壤主要污染物是Mg、B、Pb和As.宽甸县土壤重金属主要污染物是B、Mg和Pb等;而凤城市境内除发现较为严重的Ph、Mg污染,凤城镇的Hg污染也达到重度污染水平。系统分析了当地土壤污染的主要污染物类型及其原因.提出了Mg、B的污染防治对策.

Abstract: The pollution status in three counties located in the eastern mountain areas of Liaoning Provincewas investigated based on the frequency of economic activities and the distance from the pont ofpollution sources. By the methall of grey cluster and comprehensive polutbo index, the pollution situatbo was evaluated, and the types of main polutants and the causcs of sol polutbo inthese areas were spotematically analyzed. The results show that the main sol pollutants in Xiuyan County are Mg, B, Pb and As, while in Kuandian County are B, Mg and Pb. In additionto the heavy polution of Pb and Mg found in Fengcheng County, the soil environznent inFengcheng Town was also found to be heavily contaminated by Hg. Contro strateqies for soilscontaminated by Mg and Bwere suggested with the consideratbo of special soil conditions.
