贵州省务川县Hg、Cd、As等异常与环境效应研究

Study on Hg,Cd,As and Other Anomalies and Environmental Effects in Wuchuan County,Guizhou Province

本文利用贵州省务川仡佬族苗族自治县耕地质量地球化学调查评价成果,分析当地土壤环境的微量元素分布特征及地球化学异常,然后编制元素地球化学异常图,进行耕地土壤环境地球化学综合等级、耕地土壤质量地球化学综合等级评价。研究表明,各元素在不同区域土壤中的含量不同,在种植农作物时,人们应该考虑农作物种植环境的影响。

This paper uses the results of the geochemical survey and evaluation of cultivated land quality in Wuchuan Gelao and Miao Autonomous County of Guizhou Province to analyze the distribution characteristics of trace elements and geochemical anomalies in the local soil environment,then compiles element geochemical anomaly maps to evaluate the comprehensive grades of soil environmental geochemistry of cultivated land and the comprehensive grades of soil quality of cultivated land.Studies have shown that the content of each element in the soil of different regions is different,when planting crops,people should consider the impact of the crop planting environment.
