| 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: | The ecological environment is fragile in west China aeolian sand area. Large-scale underground coal mining causes soil collapse and ground fissures， which lead to a series of ecological and environmental problem such as groundwater level fall, serious loss of soil moisture and nutrient, decrease in soil enzyme activities, reduction in soil microbial communities and population, soil sandy desertification, vegetation damage, and destruction of biological diversity. This work analyzes the influence mechanism of underground coal mining on soil chemical and physical properties, vegetation, and soil microorganism, and proposes the corresponding restoration measures of destructive soil environment in west China aeolian sand area. In addition, this work suggests that the future research should focus on the restoration of soil quality and the successional law of soil microbial diversity. These findings would provide theoretic foundations and technical supports for supervising land reclamation and ecological constructions in coal mining subsidence area. |
