STUDY ON SITE OF PHYLLOST ACHYS GLAUCA McCL.IN LIMESTONE AREA

In this paper the analytical method Of Multivariate Quantified Model I is applied to study the correlation between the growth of Phyllostachys glauca McCl.and the site factors in the limestone area in Ruichang City Jiangxi, and the regression equation between site factors and the growth factors of Phyllostachys glauca McCl.is established. It is point out that the site factors are the most important ones affecting the growth of Phyllostachys glauca McCl, the regression relation and compound correlation coefficients reach extremely signifiCant levels. A-mong all site factors,the location of slope,shape of slope,direction of slope and thickness of soil are the principal factors,which affect the growth of Phyllostachys glauca McCl.Accord-ing to the principal factors, the site of Phyllostachys glauca McCl. is divided into four types.
