摘　　要：我国大型煤矿多位于干旱半干旱区,自然降雨较少且常年蒸发量过大,地下水埋藏深植物难以利用,因此土壤水分成为制约该地矿区复垦植被建设最重要的因素。综述了干旱半干旱矿区土壤质地、地形、降雨以及植被对土壤含水率的影响。发现各环境因素对土壤水分的作用机理与影响规律研究不够深入,关于土壤水分的空间变异性研究较少,矿区土壤水分的调控措施研究不够全面。提出了今后应加深对矿区各环境因素影响土壤水分作用机理的研究,运用地统计学方法及相关模型加强对土壤水分的空间变异研究,针对干旱半干旱地区的生态环境特征研究矿区土壤水分的调控措施。The large coal mines in China are mostly located in the arid and semi-arid area,the natural rainfall is less and the annual evaporation is too large,and the deeply buried groundwater is difficult to be used,therefore,soil water becomes a factor restricting the most important mining area reclamation vegetation construction.The effects of soil texture,topography,vegetation and rainfall on the soil moisture content in arid and semi-arid areas were summarized.It was pointed out that the mechanism and effect of environmental factors on soil moisture were not enough,and the spatial heterogeneity of soil moisture was less;the study on the control measures of soil moisture in the mining area was not comprehensive enough,so the mechanism of soil moisture in mining area should be studied further,the spatial variation of soil moisture researches should be strengthened using geostatistical methods and related models,and the mine soil moisture control measures according to the eco-environmental characteristics of arid and semiarid areas also should be studied.
