宿州东部煤矿塌陷区土壤重金属污染特征的研究进展

Research Progress on Soil Heavy Metal Pollution Characteristics of Coal Mine Subsidence Area in Eastern Suzhou

摘要: 随着新时代“创新、协调、绿色、开发、共享”新发展理念的提出，煤矿区生态发展问题也不断被重视起来。近年来，越来越多的学者致力于重金属的研究，本文结合宿州东部地区煤矿土壤重金属相关研究成果，将各种重金属的含量、类型的分布特征以及生态环境污染进行分析、总结、概述等。结果表明随着距煤矿中心距离的增加重金属含量有减少的趋势，重金属含量随时间的变迁有增加的趋势，煤矿塌陷区土壤重金属生态环境污染均为轻度污染。针对宿州东部塌陷区土壤重金属的研究现状，本文提出今后相关研究的着眼方向，为宿州东部煤矿塌陷区土壤重金属污染防控及生态环境保护提供参考。

Abstract: With the proposal of the new concept of “innovation, coordination, green, development and sharing” in the new ear, the problem of ecological development in coal mining areas has also been paid more and more attention. In recent years, more and more scholars are committed to the research of heavy metals, combined with the relevant research results of heavy metals coal mine soil in the east of Suzhou, this paper analyzes and summarizes the content, distribution characteristics and ecological environment pollution of various heavy metals. The results show that the content of heavy metals decreases with the increase of the distance from the center of the coal mine, and the content of heavy metals increases with the change of time. The ecological environment pollution of heavy metals in the soil of the coal mine subsidence area is mild pollution. In view of the research status of soil heavy metals in the eastern collapse area of Suzhou, this paper puts forward the focus direction of relevant research in the future, and provides a reference for the control of soil heavy metal pollution and ecological environment protection of the coal mine subsidence area in the east of Suzhou.
