摘　　要：为揭示采煤塌陷区裂缝对土壤含水量的影响,以焦作市小马煤矿采煤塌陷区为研究对象,采用数理统计方法对塌陷区裂缝线的非裂缝线的土壤含水量进行对比分析。并利用地统计方法、Surfer 11. 0对采煤塌陷区土壤含水量空间变异性进行分析。结果表明:对于同一深度的土层,裂缝区土壤含水量明显小于非裂缝区,随着水平距离的增大,裂缝对含水量的影响程度逐渐减小;各土层土壤含水量低值区大多数位于裂缝处,高值区通常位于非裂缝区。In order to reveal the influence of cracks in coal mining subsidence area on soil moisture content,the coal mining collapse area of Xiaoma coal mine in Jiaozuo city was taken as the research object,the soil moisture content of the non-fracture line in the subsidence area was analyzed by means of mathematical statistics.The spatial variability of soil water content in mining subsidence area was analyzedwith statisticssuffer 11.0.The results show that:for the same depth of soil,the soil moisture content in the fractured zone is obviously smaller than that in the non-fractured zone,as the horizontal distance increases.The degree of influence of cracks on water content decreases gradually.Most of the low soil moisture content areas in each soil layer are located in the cracks,high value areas are usually located in non-fracture areas.
