中文摘要	近些年,我国的造林绿化事业以前所未有的速度发展,一些较易造林地区已基本上完成了造林任务.森林覆盖率大幅度提高,生态环境明显改善.因此,干旱半干旱石质山地困难立地的植被恢复问题就成了今后林业工作的主要任务之一.但是石质山地由于生境恶劣及各种原因的破坏,历来造林困难很大,造林成活率、保存率不高.一些林分生长缓慢,稳定性差,林分质量低,不能发挥出较高的效益.通过应用和推广多年在石质山地植被恢复中已有的研究成果,进行现有技术的优化整合和组装配套,以提高造林成活率和保存率、提高林分和群落质量、加速植被恢复建设,是改善我国干旱半干旱石质山地困难立地植被恢复的重要举措.
英文摘要	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 serai - 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 qualirty. 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.
