| 摘 要： | 以毛乌素沙地的生物结皮层和结皮下层土壤为研究对象,对油蒿、羊柴2种植被条件下的土壤生物结皮层以及生物结皮下层土壤进行了化学性质的研究,探讨了不同植被下土壤生物结皮对土壤化学特征的影响。研究表明:生物结皮的土壤养分含量均高于流动沙地,油蒿灌丛下生物结皮的发育时间长,富集的养分含量也比羊柴灌丛的多,土壤生物结皮对下层土壤养分有明显影响,生物结皮下土壤的有机质、全效养分和速效养分的含量均高于对照流沙土壤土层,且呈随土层深度增加含量降低的趋势。

| Abstract: | Taking the biological soil crusts and the lower crust of soil in Maowusu sandland as the research object,their chemical properties at the conditions of Artemisa ordosica and Hedysarum were studied to investigate the effect of the biological soil crusts on the soil chemical characteristics under different vegetation.The results showed that the nutrient content of the biological soil crust was higher than the flow of sand,the duration of the development was longer and the nutrient content was richer in the sc... |
