重金属污染农田土壤修复效果评价指标体系分析研究

Analysis on evaluation index system of soil remediation effect of heavy metal contaminated farmland

我国改革开放的初期,在经济发展的过程中没有认识到环境保护的重要性,经济的发展建立在牺牲环境的基础上。重金属污染对农田土壤的污染就是重要的体现之一,当前我国已经认识到重金属污染对身体健康和生态破坏带来的不利影响,开始重视土壤的修复,为了对土壤修复工作进行评价,需要建立起完善的评价指标体系。本文主要从我国农田重金属污染的概况、农田土壤修复相关指标、重金属污染农田土壤修复评价指标的选择原则、土壤修复评价指标使用的建议四个方面进行阐述,为我国生态修复工作的进步和发展提供参考和建议。

In the early stage of China's reform and opening up,the importance of environmental protection was not recognized in the process of economic development.The economic development was based on environmental sacrifice.Heavy metal pollution on farmland soil is one of the important manifestations.At present,China has recognized the adverse effects of heavy metal pollution on physical health and ecological damage,and started to pay attention to soil restoration.In order to realize the evaluation of soil restoration,a complete evaluation index system should be established.This paper mainly elaborates on the general situation of heavy metal pollution in farmland in China,relevant indexes of farmland soil remediation,selection principles of evaluation indexes of soil remediation in farmland polluted by heavy metal,and Suggestions on the use of evaluation indexes of soil remediation,so as to provide references and Suggestions for the progress and development of ecological remediation in China.
