干旱半干旱区煤炭资源开采对水资源及植被生态影响综述

煤炭资源开采对水资源的赋存和循环产生相当程度的破坏,进而影响到对水资源依赖性较强的表生植被生态,尤其在干旱半干旱地区。着重阐述了煤炭资源开采对地表水、地下水、土壤水以及植被生态的影响,介绍了旱区地下水和植被生态的关系,重点分析了旱区植被生态耗水的最新研究进展,并对后期相关研究的开展提出了可行性建议。本研究有助于认识旱区煤炭资源开采对水资源的影响及其引发的生态效应,为今后采煤工艺改善、地下水资源开发和生态环境保护提供科学依据。

Effects of coal resources' exploitation on the water resource and vegetation in arid and semi-arid region

The circulation and occurrence of water resource suffers damage from the coal resources'' exploitation, which influences the vegetation that has strong dependency on water resource, especially in arid and semi-arid region. In this paper the effect of coal resources'' exploitation on the surface water, groundwater, soil water and vegetation is elaborated. The relationship between groundwater and vegetation is introduced. The advanced research of water consumption character of vegetation is also analyzed, and some feasible suggestions for later studies are put forward in this paper. The results are useful for understanding the impact of coal resources'' exploitation on water resource and its ecological effects, and then providing scientific basis for coal mining craft improvement, groundwater resource exploitation and ecological environmental protection.
