Calculation of quantity of soil evaporation takes an important part in moisture content prediction,rainfall surface flow calculation and evaluation of water resources.

The water surface evaporation and soil evaporation in the forest is not as half out of the forest,and the forest evaporation is calculated according to the material of soil containing water quantity in the forest.

Rules of soil evaporation and plant transpiration under different land use patterns in the sloping land of red soil;

Soil evaporation in artificially re-vegetated sandy areas of Hunshandake;

Field experimental study on the measurement of soil evaporation using different types of micro-lysimeters;

We have systematically studied the soil water evaporation of planted vegetation in the southern and northern mountains of Lanzhou city.

Based on the analysis of fractal dimension of soil aggregates and soil pore in low suction range,the influence of the wheat straw,comminuted,aminated or mingled with inorganic soil amendment,on the soil structure,soil bulk density,soil porosity and characters of soil water evaporation,after mixed with the soil was studied.
