Effect of wind erosion on the fertility of farmland at Bashang of Hebei;

Research advances in affecting factors and prevention techniques of soil wind erosion;

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.

Based on these analyzing results the paper has also quantitatively analyzed the wind erosion possibilities of the different land types, concerning the recent climate records in the studied area.
