【摘要】：中国西部风沙区生态环境脆弱,煤炭井工开采造成土体坍塌,产生地表裂缝,导致地下水位下降、土壤含水量减少、土壤养分流失、土壤酶活性降低、微生物数量和群落结构发生变化、土壤沙化、植被死亡以及生物多样性破坏等生态环境问题。主要剖析近年来煤炭地下开采对西部风沙区土壤理化性质、土壤酶活性、土壤微生物和植被生长等方面的影响机制,提出塌陷区土壤环境破坏的修复措施。指出今后的研究应集中于采煤塌陷区土壤质量的恢复和土壤微生物多样性的演替规律方面,为中国西部风沙区采煤塌陷地的生态修复提供理论基础和技术支持。
[Abstract]:In the west of China, the ecological environment of wind-sand region is fragile, and the coal mining results in soil collapse and surface cracks, which leads to the decrease of groundwater level, the decrease of soil water content, the loss of soil nutrients and the decrease of soil enzyme activity. The changes of microbial quantity and community structure, soil desertification, vegetation death and biodiversity destruction and other ecological environmental problems. This paper mainly analyzes the influence mechanism of underground coal mining on soil physical and chemical properties, soil enzyme activity, soil microorganism and vegetation growth in western wind-sand area in recent years, and puts forward remediation measures for soil environmental damage in subsidence area. It is pointed out that the future research should focus on the restoration of soil quality and the succession law of soil microbial diversity in coal mining subsidence area, and provide theoretical basis and technical support for ecological restoration of coal mining subsidence land in western China.
