长期以来,我国人工林发展重造轻管,重数量轻质量的现象非常普遍。林分生长较差,生产力低下。低下的生产力水平,很难承担未来木材生产的重任。因此,尽快大幅度提高人工林生产力,已成为当前我国林业发展的中心任务之一。一、立地条件对人工林生产力的影响林木生长的优劣取决于立地条件的综合作用,立地条件愈优越,林木生长愈好。目前,国内外多用立地指数来表示森林生
For a long time, it is very common that the development of plantation in our country should be rebuilt and light weight should be emphasized. Stands are poorly grown and productivity is low. Low productivity levels, it is difficult to undertake the future of wood production task. Therefore, as soon as possible to substantially increase the productivity of plantations, has become one of the central tasks of China’s forestry development. First, the site conditions on plantation productivity The pros and cons of forest growth depends on the combined effect of site conditions, site conditions, the more superior, the better the growth of trees. At present, multi-use domestic and international index to forest health
