Studies on Evaporative Effect and Soil Evaporation About Two Kinds of shelterbelts

两种防护林蒸发效能和土壤蒸发的对比研究

Because the evaporation is great more than rainfall, and the ground water is deep, soil water is always in the step of wane condition and the soil nutrient are also leanness and available nutrients are scantily, which makes the eco-environment of the plateau very fragile.

由于蒸发潜势远大于降雨量，而地下水埋藏又很深，致使土壤水分经常处于水分亏缺状态，加之水土流失严重，土壤贫瘠，基础肥力低，有效养分缺乏，生态环境十分恶劣。

The contrast study on reducing soil evaporation with two kinds of Poplar Shelterbelts

两种杨树防护林减少土壤蒸发作用的对比研究

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。

Three boundary condition expressions of unsaturated soil slope under rainfall infiltration and evaporation conditions are presented.

讨论了非饱和土边坡在入渗、蒸发条件下的三类边界条件表达形式.

The amount of the soil evaporation in Eucalyptus wood slope was the highest, followed by the nature grass slope, while it was the lowest in nature slope.

不同地类的土壤蒸发量为桉树林坡面>自然草坡>阶间草坡。

Effects of different straw mulching quantity on soil evaporation and soil temperature in summer corn field

不同麦秸覆盖量对夏玉米田棵间土壤蒸发和地温的影响

Under different levels of soil moisture, the soil water evaporation covered by litter with the thickness of 0.5cm~ 2cm was less than 7.95%~ 56.79% of the soil without litter covering.

0.5mm～2mm枯落物覆盖下不同含水量的土壤水分蒸发比无覆盖的土壤减少7.95%～56.79%，枯落物层减少土壤水分蒸发的效应随枯落物层厚度和土壤含水量的增大而增加。
