造林成活率是衡量造林技术水平的主要标志之一。提高造林成活率,对于扩大森林资源,提高林木覆被率具有重要意义。自建国以来,我省人工造林成绩很大,但是造林成活率和保存率都较低,是全省林业生产急须解决的问题。为探讨影响我省主要造林树种造林成活率的因素,总结经验,为林业领导部门提供依据,更好的指导造林工作,山东林学会造林专业委员会于1983年5月在潍坊市召开会议。组织力量,拟定调查方案。会 Afforestation survival rate is one of the main indicators of the level of afforestation technology. Raising the survival rate of afforestation is of great significance for expanding forest resources and improving the forest cover rate. Since the founding of the People’s Republic of China, the achievements of afforestation in our province have been very good. However, the survival rate and preservation rate of afforestation are both low, which is a problem which the province’s forestry production urgently needs to solve. In order to discuss the factors affecting afforestation survival rate of major afforestation species in our province, summarize experience, provide basis for forestry leaders and guide afforestation better. Afforestation Committee of Shandong Forestry Society held a meeting in Weifang City in May 1983. Organize forces and formulate survey plans. meeting
