VIEW ON THE FACTORS AFFECTING THE SUSTAINABLE MANAGEMENT OF CHINESE FIR PLANTATION
影响杉木人工林可持续经营因素探讨

The gradual drop of soil fertility and stand productivity of Chinese fir plantation with the increase of continuous plantation would directly hamper its sustainable management. The major factors which hinder the sustainable management of Chinese fir plantation include not only the vulnerable subtropical red soil ecosystem which Chinese fir grow in, but also the unitary community structure and the biological characteristic of this artificial forest community. Additionally, the traditional culture system of Chinese fir including controlled burning lead to the degradation of soil ferti lity. According to the current situation of the Chinese fir plantation management, it is necessary to lower the disturbance intensity of culture system to the forest land, especially to avoid the controlled burning repeatedly. Meanwhile, experimental sustainable management models of Chinese fir plantation should be developed and evaluation indication system should be studied so as to identify sustainable management models suitable to artificial fir forests in different regions. This is of great significance to the sustainable management practice of forestland in southern China.
