我国特有孑遗植物水松濒危原因及其保护对策
The endangering causes and protection strategies for Glyptostrobus pensilis,an endemic relict plant in China
摘要
Abstract
Glyptostrobus pensilis,distributed mainly in several southern provinces of China,was catalogued as an endangered species and subjected to first-ranking protection level in China.This paper analyzed the reasons causing the endangered status of G.pensilis from the aspects of the reproductive biology,ecological factors stress,human disturbance and genetic diversity based on a survey of their native areas.The results showed that: the original biological characteristics constrained the size of their survival,and high level habitat requirements restricted their continued proliferation,and the habitat fragmentation and the sharply declining number of individuals caused by human activities were the direct factors for the endangered status of G.pensilis,while lower level of genetic diversity was the internal factor.Based on the status of G.pensilis,the effective strategies for its protection should include both in situ conservation and ex situ conservation.In situ conservation it should be emphasized to protect the current living individuals from human damage so as to promote the natural regeneration.In ex situ conservation,establishing a propagation center at a beneficial place would also be imperative for restoration and reconstruction of G.pensilis populations.Meanwhile to increase then populations by artificial breeding species would be feasible.关键词
