徐州市北郊农田土壤重金属污染趋势面分析及其容量研究

Abstract

Abstract: Surface analysis , a mathematical method , was applied in the investigation of soil heavy metal pollution in northern suburb farmland of Xuzhou City. Information as heavy metal distribution, pollution status and so on are reflected in a map ,the results turned out to be satisfactory. A dynamic equilibrium model was developed in light of current heavy metal input and output in farmland. The soil heavy metal capacity was calculated and future pollution trend was predicted. These would provide technical basis for the treatment of soil pollution.

Key words: soil, heavy metal, pollution, surface analysis, environmental capacity
