In arid and semi-arid zones, appearance of microbiotic crusts will change the surface condition of sand dunes greatly.

在干旱、半干旱地区，微生物结皮的出现完全改变了沙丘表面状况。

In artificial vegetation-fixed sandy dunes, microbiotic crusts always occur with stabilizing of the environmental conditions in vegetation regions.

在沙坡头人工植被固沙区，微生物结皮是伴随着植被区环境的日趋稳定而出现的。

Intercepted precipitation and enhanced evaporation by microbiotic crusts were the two main factors threatening the water reservoir in sand dunes.

微生物结皮拦截降雨和提高蒸发，是微生物结皮威胁沙丘土壤水库的两个重要因素。

Using the survey data of several indexes as well as field experimental data of soil hydrology of microbiotic crusts in artificial vegetation-fixed sand dunes in Shapotou area, the impacts of microbiotic crusts on soil hydrological processes which included the penetration, interception and evaporation processes of precipitation were examined, and their mechanisms were also studied. The security problem of vegetation-fixing system due to the changed soil water environment in fixed sand dune area was analyzed further.

本文在上面的立意下，我们对沙坡头人工植被固沙区对微生物结皮的若干指标进行了详细的调查和试验，并安排了一系列微生物结皮土壤水文过程试验，从不同的角度揭示了微生物结皮在降雨渗透、拦截和蒸发过程中的作用，及其对降水在沙丘土壤剖面中的水分分配过程和格局的影响，并进一步分析了微生物结皮对固沙区土壤水环境的影响和植被固沙体系的安全问题。

By field sampling, some original soil microbiotic crusts were gathered and their physico-chemical properties were analyzed. The results revealed that the longer the sand dunes have been fixed, the thicker and the more biocrusts are formed.
