soil crust

Hydrophysical characteristics of biological soil crust in an arid desert area

荒漠地区生物土壤结皮的水文物理特征分析

The surface crust of red soil formatted after rain has great impacts on runoff and sediment. It can affect the infiltration, evaporation and moisture of soil. Meanwhile the cycle of soil water may be changed by the surface crust.

红壤在降雨之后形成的地表结皮，不但影响土壤产流产沙，也影响降水入渗、水分从地表蒸发以及土壤水分状况，并可能改变土壤水分循环。

The crust seals the soil and prevents the evaporation of water.

这层表皮把土壤封闭,防止水份蒸发.

Mayor Robert Silva of Mendota, in the heart of the agricultural Central Valley, said unemployment among farmworkers had soared as the soil turned to crust and farmers left half or more of their fields fallow.

门多塔市位于农业区中央山谷的心脏地带，市长罗伯特·席尔瓦（Robert Silva）说，农场工人失业率出现了飙升，因为土壤干燥起壳，至少一半的土地已经休耕。

With continuing of rainfall, the influence of soil-aggregated degree was very great. Seventhly, mutual effect between soil crust and raindrop splash was studied, the result showed that splash erosion rate was greatly increased, once soil surface crust was formed.

雨滴溅蚀和结皮效应对土壤侵蚀影响的试验研究七、表土结皮形成对土壤溅蚀的影响：随着表土结皮的逐渐形成，土壤抗侵蚀能力增强，土壤溅蚀速率急剧减小。

The presence of crust lying on soft soil foundation changes the mechanics characteristic of soil foundation.

软土地基上硬壳层的存在,改变了软土地基的受力特征.
