Gully region of loess plateau is the centre of locust plistribution in China. The climate and soil condition are suitable for locust growth in the region，but its growth quantity in distinct with different topography.Locust growfh pattern in Wangdong gully have been analysed ecologically，indicating the followings. (1)In different habitat，the most important factor leading to difference of stand condition is water condition.(2) The mainfactor affecting locust growth were solpe location and-slope position. (3 )According to the soil water condition in different topographical location,the authors suggest some forms of replace and transform locast plantation,in steep sun-slope locust plantation which growth stagnated should be transform，and cultivate higher-growing plantation should centre on middle gully and lower location where the terrain slopes gentle.
