Abstract:

In the bamboo forest ecosystem, the bamboo yield is the essentially quantitative features of the economic targets and the ecological index.The correlation between the yield of branches and leaves and the factors of the bamboo stand are elaborated in this paper, and the mathematical linear and non-linear models are simulated. According to the correlation coefficient and the standard error, the models are primarily chosen. With the colinearity determination to decide which to use and to compare the C_p value with VIC (Variance inflation factor), the optimum mathematical models were obtained, which were high precision and practical, so as to guide production practice.

Key words: Phyllostachys heterocycla cv.pubescens, Biomass, The C_p value, The determination of colinearity
