中文摘要：
以毛乌素盐渍化沙地典型的裸沙丘、放牧草地和人工灌木林地下的土壤为研究对象,通过野外实地观测、采样和室内实验,对土壤含水率、全盐量、pH值、有机质、土壤容重进行测定分析。结果表明：人工植被样地的土壤容重、土壤盐分、土壤pH值明显低于坡后丘间草地、坡前丘间地、迎风坡坡中、迎风坡坡底、迎风坡坡顶、沙脊线处。植被恢复对降低土壤盐分、土壤容重和土壤pH值有一定积极作用。同时发现人工植被样地对提高土壤有机质也有一定的影响作用,人工植被样地土壤有机质含量达到0.60%,而坡前丘间地仅为0.27%。
英文摘要：
Taking the soil of sand dune,grazing grass and artificial subterranean as research object,by use of the field observation,sampling and lab analysis,soil water content,soil total salt content,soil pH value,soil organic matter and soil bulk density were measured and analyzed.The results showed： soil bulk density,soil salinity and soil pH value in artificial vegetation plots were significantly lower.Vegetation restoration has played a positive role to reduce soil salt,soil bulk density and soil pH value.Meanwhile,the artificial vegetation plots also can improve the soil organic matter.The soil organic matter in artificial vegetation samples was 0.60%,but the one in the land between the dunes before the slope is only 0.27%.
