| 摘 要： | 通过对毛乌素沙地东南边缘沙地采煤塌陷对固定沙丘的水分时空动态分布规律影响的研究表明,沙土含水量的时空变化与降雨季节和降雨量有密切关系。沙丘0-80cm土层为土壤水分受降雨影响的活跃层,其中0-40cm土层变化最为明显。沙丘的迎风坡和坡顶含水量低于沙区的其他部位,但受沙丘高度以及植被和土壤质地的影响这种差异并不明显。在沙区采煤引起的地表塌陷对土壤水分的时空变化影响较小。

| Abstract: | The influences of coal mining collapse on the soil water dynamics in the fixed dune onthesoutheasternedge of MuUssandyarea were studied.The results showed that the spatio-temporal changes of the water in the sand soil were related to the rainy season and rainfalls.The soil moisture layers of the dune between 0cm and 80cm deep were mainly influenced by the rainfall, especially between 0cm and 40cm deep the change was evident.The soil moisture of dune slope of windward and the dune top were lower than other part of the dune.But the different was not evident because of the influence of the dune height,the vegetation and soil texture.The influence of coal mining collapse on water spatio-teporal changes in the sand soil was not obvious. |
