The objective of this study is evaluating the effect of the wind shelter forest on the mitigation of the intrinsic environment and the improvement of the soil characteristics. Firat, the field investigation is conducted to clarify the method of the development of the wind shelter forest in the study site, Naiman. It is clear the process of the development of the wind shelter forest is planned, considering the geographic and climate conditions in the study site. The mictometeorological observation is conducted at the wind shelter forest and bare field in the study area. In the wind shelter forest, the air temoerature decreased, and the relative humidity increases, comparing with the bare field. The experiments on the soil physical and chamical characteristics are conducted to evaluate effect of the wind shelter forest on the soil improvement. At the wind shelter forest, the improvement of the soil water retention can be obtained, comparing with the value at the bare field. The soil chamical characteristics at the wind shelter forest, including organic matter content, cat iron capasity (CEC), pH, and EC, are improved comparing with the value of the bare field.
