| 摘 要： | 筇竹（Qiongzhuea tumidinoda）是中国特有珍稀濒危植物，是滇东北中山湿性常绿阔叶林中灌木层的主要植物，筇竹笋是当地农民重要的经济来源。为合理经营筇竹林，最大程度地发挥其经济效益，文章通过调查滇东北筇竹生长的立地因子，确定影响筇竹生长的主导因子，对筇竹生长的立地类型进行划分。结果显示：1）土壤厚度、石砾含量、海拔、坡度是影响筇竹生长的主导因子；2）根据不同海拔的土壤类型及土层厚度，将筇竹林的立地划分为14种类型，不同类型的立地特征差异明显；3）不同立地类型的筇竹生长状况差异显著，其中位于中海拔区的筇竹生长表现较好，在相同海拔区以厚土层中的筇竹生长表现为最好。

| Abstract: | Qiongzhuea tumidinoda is a rare and endangered plant endemic to China, mainly growing in the shrub layer of the wet evergreen broad-leaved forest in the middle mountains of northeastern Yunnan province. Its bamboo shoot is an important source of income for local farmers. In order to manage the bamboo forest reasonably and make full use of its economic benefits, this paper investigates the site factors to the bamboo growth in northeast Yunnan province to determine the main factors affecting the bamboo growth and classify the sites where the bamboo grows. The results show that:1) Soil thickness, gravel content, elevation and slope are the main factors affecting the growth of Q. tumidinoda; 2) The sites are classified into 14 types according to the soil types and soil layer thickness at different altitudes, and the site characteristics of different types are obviously different; and 3) The growth of Q. tumidinoda is obviously different in different site types, among which the bamboo growing in the middle elevation area boasts better growth performance than those in the thick soil layer at the same elevation area. |
