摘　　要：通过对安太堡矿区不同类型结皮覆盖下不同深度土壤含水量的野外动态监测和实验室测定,研究了不同类型结皮与土壤水因子之间的相互影响关系。实验结果表明:第一,生物结皮可以增加表层土壤持水力但对深层土壤持水力几乎没有影响;第二,土壤含水量在不同类型结皮的影响下,随着土层深度的增加,生物结皮表现为先下降后升高的趋势,物理结皮则是表现为一直升高的趋势;第三,在不同类型结皮影响下不同土层土壤水分含量日动态变化受到土壤水分蒸发、深层土壤水和大气凝结水补给的影响。Through the field dynamic monitoring and laboratory measurement of soil moisture content at different depths under different types of crusts in Antaibao mining area,the relationship between different types of crusts and soil water factors was studied.The experimental results show that:first,biological crust can increase the water holding capacity of surface soil but has little effect on the water holding capacity of deep soil.Secondly,under the influence of different types of soil crusts,with the increase of soil depth,soil water content of biological crusts shows a trend of decreasing first and then increasing,while physical crusts shows a trend of increasing all the time.Thirdly,under the influence of different types of crusts,the diurnal dynamic change of soil moisture content in different soil layers is affected by soil moisture evaporation,deep soil water and atmospheric condensation water supply.
