我国西北地区浅埋煤层开采对生态环境影响研究

Study on the effect of coal mining on the ecological environment in the area of shallow buried coal seam in northwest China

对我国西北浅埋煤矿区煤炭开采引起的生态环境问题研究进展进行了总结,分别阐述了煤炭开采对地表塌陷、水资源、水土流失、植被覆盖、土地沙漠化等不同生态指标影响的研究现状。指出了当前研究存在问题和不足:浅埋煤层开采对整个生态指标体系影响的研究不够全面、各生态指标之间互动关系研究不足等,同时针对这些问题提出了新的研究思路和方法,为西北浅埋煤矿区生态环境保护提供理论参考依据。

This paper summarized the research progress about the effect of coal exploitation on ecological environment in the area of shallow buried coal seams in northwest China,and elaborated the research status of the impact of mining shallow buried coal on surface subsidence,water,soil and water loss,vegetation cover and land desertification,respectively. Moreover,there are some problems and shortcoming in the current research,for example,the effect of shallow coal seam mining on the whole ecological index is not comprehensive enough,and study the interaction of the ecological indicators is deficiency. New research ideas and methods for these questions were proposed so as to provide a theoretical reference for protecting the ecological environment of shallow buried coal areas.
