中文摘要：

现以神府东胜煤田为研究背景，选择两个主要塌陷阶段分布区大柳塔矿区双沟村原农场和补连塔矿区原补连沟村作为研究区，采用野外勘查、取样测试与室内参数分析综合研究的方法，对采矿塌陷不同阶段表层包气带土壤水分进行对比分析，结果表明，采矿塌陷后，塌陷区尤其是塌陷裂缝区的土壤含水量与土壤储水量值均小于未塌陷区，说明塌陷裂缝对土壤的持水作用具有非常不利的影响，塌陷区与未塌陷区的地表植被覆盖情况也证实了这一点。值得说明的是，塌陷稳定区经过长时间的沉压、密实后，其土壤层结构、土壤水分含量等性质以及地表植被覆盖程度均越来越趋近于未塌陷区，对于沙生植被而言，虽得不到充分的供水条件，但仍能维持其生长。说明塌陷区经过长时间的稳定后，可以恢复到具有一定生态功能的程度。

英文摘要：

Field survey,sampling and testing were used to discuss the characteristics of soil water content between different subsidence stages. The results show that after mining collapsing, the soil water content and soil water-storage capacity of subsidence area is obviously less than the nature area, especially for the fissure zone. It is indicated that the collapsing fissures are extremely disadvantageous for soil water-holding capacity and the conditions of vegetational cover on the subsidence area also confirmed this result. Noticeably, after long time sediment and stabilization, the soil structure,soil water content and the vegetational cover conditions of subsidence area are tend to those of nature area. Although abundant water support is unable,it is favor to the sand plant for maintain their growth. In conclusion, a certain extent of ecological function of subsidence area will get back after long time stabilization.
