Several suggestions are presented through the analysis of plantation production situation of artificial locust and its updating and succession processes in Wangdong watershed.The construction of locust forest should be combined with its updating during the forest2grass vegetation construction in the gully area of the loess plateau.The measures like clear-cutting and rootsprout and preferred thinning-cutting should be taken to update it.Cutting and reasonable use of locust forest should be based on second-generation locust forest growth and water use situation.At present

it is not adequate to cultivate the third generation.It is better to preserve herb and shrub plants so that it is replaced by a natural herb community firstly.The roles of vegetation in preventing soil erosion should be played at the same time in order to improve the ecological environment.
