Characteristics and present silvicultural strategies of vegetation in loess plateau of northern Shaanxi province

It is concluded that potential distribution of broad leaved oak forests on the loess plateau of northern Shaanxi province ends at north border of Weibei loess plateau, namely along Longxian, Binxian and Yijun, Tongchuan and Huanglong county, after a comparative analysis of uptonow research results. Soil substrates is already dried and impoverished after a serious destruction and soil erosion. However, these are not their real situation. Soil substrates may gradually get recovered through vegetation reconstruction. Pioneer tree species should be selected at first for vegetation recover. Juvenile plantations should be modified in time after a certain period of afforestation, so that to direct them to approach potential nature forests (vegetation). Meanwhile, a system of sustainable management should be set up too.
