Ecological prediction model and experimental simulation of soil water erosion in small watershed:taking Liudaogou small watershed as an example;

Research status and future development of effects of chemical factors on soil water erosion;

A review of soil degradation and affecting factors of water erosion;

Based on the author s study of environmental evolution and the prediction in the coming 10 years in Beijing area since mid Holocene, this paper forms a model of remote sensing information of soil hydra-erosion with SPSS software and works out the map of soil hydra-erosion of Beijing area in the contemporary time by GIS.

An indicator system was proposed for dynamic assessment of soil anti-erodibility by water (SAEW).

Review on research methods of soil corrosion for buried pipeline steels;

Research on the Methods of Analyzing Electrochemical Noise and Its Application in Soil Corrosion Processes;

A gray relational analysis was applied to deal with the data obtained by measuring the buried pipeline with is the Liaohe oilfield,and the the degree at which soil corrosion factors affect the corrosion speed is described.

Study of the effect on different distribution modes of Artemisia sphaerocephala to soil wind erosion is of great significance to ecological construction and preven- tion against soil wind erosion in the fixed and semi fixed sands.

Wind tunnel experiments were conducted to Research the change process of soil wind erosion with the change of PAM controlling the soil wind erosion under the condition of the constant wind velocity of 14 s/m and the constant blown angle of 5°.

A soil wind erosion experimental plot was set up in the alluvial sandy land of old yellow river,which is in Xiajin County of Shandong Province,and the soil wind erosion quantity was tested with measuring scale method in the observation farmland shelter-forest network and the comparison place.
