摘要
株州市土壤重金属污染的主要原因是工厂排放有害气体,或是水体污染物随灌溉进入土壤.采用对应分析方法,将市区土壤重金属污染分为3种类型.靠近工业污染源附近,镉的含量及污染指数高;大部分土壤受多种重金属污染;水稻土主要表现为铅的污染.
In this paper, monitoring analyses to the Heavy metal content of various types of soil specimens in the urban district of Zhuzhou City are carried on. And on the basis of stan-dardizing disposition of monitoring analyses data, the method of Corresponding Analysis is taken to divide the types of geographic spatial distribution of heavy metal pollution of soil in urban district. Thereby, the simple method, only taking synthetical pollution index to divide the types of pollution previously, is changed and it can provide scientific basis for the defensive ways of heavy metal pollution of soil of farmland in urban district and for the reasonable utilization and a long-range plan of land.
