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

Pollution Surface Analysis and Capacity Study for Heavy Metal in Northern Suburb Farmland of Xuzhou City.

本文把趋势面分析的数学方法应用于土壤重金属污染调查研究中,使重金属含量分布、污染情况等众多信息集中反映在一张图上,结果令人满意。同时结合当地重金属输入、输出情况,建立了动态平衡模式,计算出该区重金属的土壤环境动容量,并进行了土壤环境预测,为综合治理土壤污染提供了科学依据。

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.
