A Study on Vegetation Recovery Technique in Arid and Semi-arid Stony Hillside Difficult Plot

In China, the afforestation process is developing more rapidly in recent years than in any time before. Most areas of non-forest land easy to be afforested have been covered with forests. Forest coverage has been enhanced by a big margin and ecological environment has been obviously improved. Thus the vegetation restoration in sites difficult to be afforested in arid and semi-arid regions becomes the main tasks for foresters. But it is very difficult to afforest in stony hillside in terms of low survival rate of young trees in current years because of its poor environment and deterioration. Some stands whose trees grow slowly have poor stability and low quality so that the stands cannot produce high benefits. To promote the vegetation restoration in the sites, research results which have been used in stony hillside vegetation restoration should be applied and extended to increase the survival rate of young trees planted in the afforestation sites and to improve stand quality. It is an important act to the promote vegetation restoration in the sites difficult to be afforested in stony hillside zones in arid and semi-arid regions through applying and extending the existing techniques in order to increase forestation survival rate and conservational rate, and to improve the quality of stand and community, and speed up vegetation restoration.
