摘　　要：根据调查资料,对昆明地区慈竹生长与立地条件的关系进行了研究。结果表明:无性系株高与坡度、胸径与海拔呈负相关;无性系胸径、株高与土层厚度和湿度呈正相关。通过回归分析,建立无性系株高、胸径与坡度、海拔、土层厚度、湿度之间的方程,为慈竹造林地选择和立地质量提供理论依据。Based on the investigation in Kunming regions, the relationship between the growth of Neosinocalamus affinis clonal population and the site condition was analysized in this paper. The results showed that the height of ramets decreased with the increase of slope gradient and the DBH reduced following the increase of the altitude. On the contrast, the height and DBH of the tamers increased with the increase of the soil depth and soil moisture. And the equations between the height and DBH of the ramets and slope gradient, altitude, soil depth and soil moisture were worked out by regression analysis, which provided a foundation for the site selection and assessment of the bamboo plantation.
