The objectives of this research are to study the pursuing effects and efficiency of strawmulch on soil water evaporation reducing and try to find a new way of amelioration of coastal salinesoils.

By using mcirolysimeter,a laboratory simulation experiment was conducted to study the effects of the grain size and thickness of dust deposits on the soil water evaporation and salt movement in the hinterland of the Taklimakan Desert.

Comparison of soil moisture evaporation under different vegetation coverage conditions;

The Dynamical models of soil moisture evaporation under conditions with varied quantity of crop stalk mulch were developed on simulative trial in lab,and the relation of soil moisture evaporation to the quantity of stalks applied under different moisture contents was studied.

In order to study the effect of retention rate and air content on the plastic shrinkage and cracking of mortar,relations between retention rate and air content with the rate of water evaporation and the plastic tensile strength was studied under three different conditions.

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.
