| 摘 要： | 为保护与利用狭叶方竹资源,采取作业设计调查法对贵州湄潭县狭叶方竹资源进行普查。根据普查结果,将影响狭叶方竹生长的立地环境因子筛选归类作为划分其群落类型的依据。普查结果显示,狭叶方竹在相似气候条件和中偏碱性土壤上,影响其生长的主导因子为海拔、坡位、坡向、土层厚度和林分上层郁闭度。按有明显影响的海拔、坡位和土层厚度因子将狭叶方竹林区划为6个群落类型区、36个适宜立地类型。在适宜立地类型基础上,结合狭叶方竹对林分上层林木郁闭度的适应性,将狭叶方竹林划分为144个群落类型。对区划的6个群落类型区的狭叶方竹资源现状、经营与利用方式进行了综合评价。

| Abstract: | In order to protect and utilize the resources of Chimonobambusa angustifolia C. D. Chu et C. S. Chao, an investigation was conducted in Meitan County, Guizhou Province, using operation design survey method. According to the investigation results, the site environmental factors that affect the growth of C. angustifolia were screened and classified to be the basis for classifying its community type. The results showed that the dominant factors affecting C. angustifolia growth were the altitude, slope position, exposure, soil thickness and canopy density under similar climatic conditions and netural-alkaline soil. With the factors of the altitude, slope position and soil thickness with obvious influence, C. angustifolia forest could be classified into 6 community type areas and 36 suitable site types. Considering the adaptation of C. Angustifolia to the canopy cover, we classified them into 144 types of community. Finally, we made a comprehensive evaluation of the resources state, management and utilization of C. angustifolia in the 6 community type areas. |
