Abstract:The purpose of site classification is to predict productivity and to devise an accurate choice of planting area in order to achieve better yield for Chinese fir.In the period of 1978—1980, the site type is classified and the potential productivity of Chinese fir is properly estimated in some of major planting areas. In this paper, surrey data of southern proveinces for Chinese fir are summarized to cope with the complexity of natural environmental condition in each surrey area a multiple-factor method, integrating with geomorghology, feature of bedrock, local topography, soil and Chinese fir growth is established. The type district, type subdistrict, type section and site type are determined based on above-mentioned factors respectively. A vast amount of surrey data also showed that the classification system is quite suitable for the conditions of Chinese fir forest and it may be used in the silviculture practice.
