摘要
运用多元数量化模型Ⅰ分析方法，研究了石灰岩地区淡竹生长与立地因子之间的相关性，并建立了立地因子与淡竹生长因子之间的回归方程。研究指出：立地因子对淡竹生长影响极大，回归关系和复相关系数均达极显著水平；在众多的立地因子中，坡位和坡形的影响最大，其次是坡向，土层厚度的影响也比较明显，坡位、坡形、坡向和土层厚度是影响淡竹生长的主导因子，其它因子的影响相对较小；根据影响淡竹生长的主导因子，把影响淡竹生长的立地条件划分为４种立地类型。
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.
