Abstract:
In this paper, 337 set growth data were collected from the pure and same age stands of I -69 in Jiangsu, Anhui, Hunan and Hubei Province, China. Through analysing the key factors affecting crop of Ⅰ -69 stand, age of tree, stand density and site grade are determined as predictors. With the method of Ordinary Least Squares, the single-crop prediction models are developed. According to the models, variable density crop tables for the pure and same age stands of Ⅰ -69 are also worked out.
