云南省第二次重点保护野生植物资源调查研究

Second Investigation of Key Protected Wild Plant Resources in Yunnan Province

对云南省国家重点保护野生植物资源进行了全面调查,共调查到目的物种134种,分布面积累计达159970.0795 hm^(2),总株数达147256930株。通过对调查目的物种的种群规模、分布面积、分布点、群落地位、年龄结构和外部环境状况进行统计分析,表明云南省重点保护野生植物资源物种存在种群数量整体偏低、分布区域狭窄、群落和年龄结构不稳定等潜在威胁。

A comprehensive survey was conducted on national key protected wild plant resources in Yunnan Province.A total of 134 target species were investigated,with a cumulative distribution area of 159970.0795 hm^(2) and a total of 147256930 plants.The statistical analysis of the population size,distribution area,distribution point,community status,age structure and external environmental conditions of the survey target species showed that the key protected wild plant resources in Yunnan Province had potential threats,such as overall low population,narrow distribution area,unstable community and age structure and so on.
