【摘要】：中國西部風(fēng)沙區(qū)生態(tài)環(huán)境脆弱,煤炭井工開采造成土體坍塌,產(chǎn)生地表裂縫,導(dǎo)致地下水位下降、土壤含水量減少、土壤養(yǎng)分流失、土壤酶活性降低、微生物數(shù)量和群落結(jié)構(gòu)發(fā)生變化、土壤沙化、植被死亡以及生物多樣性破壞等生態(tài)環(huán)境問題。主要剖析近年來煤炭地下開采對(duì)西部風(fēng)沙區(qū)土壤理化性質(zhì)、土壤酶活性、土壤微生物和植被生長等方面的影響機(jī)制,提出塌陷區(qū)土壤環(huán)境破壞的修復(fù)措施。指出今后的研究應(yīng)集中于采煤塌陷區(qū)土壤質(zhì)量的恢復(fù)和土壤微生物多樣性的演替規(guī)律方面,為中國西部風(fēng)沙區(qū)采煤塌陷地的生態(tài)修復(fù)提供理論基礎(chǔ)和技術(shù)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.
