浙江楠研究现状及濒危保护建议

The status quo research,the rescue and conservation strategy for Phoebe chekiangensis

浙江楠(Phoebe chekiangensis C.B.Shang)是国家二级珍稀濒危保护植物,我国特有树种。该种群分布狭窄,自然更新能力较差,此外,由于该物种具有较高的经济价值和开发利用前景,人类干扰及盗伐现象严重,致其种群数量减少,逐步走向衰亡。从资源状况和地理分布、种群生态学与生物多样性、种子萌发与生理生化研究、容器苗育苗技术、造林技术以及濒危的原因几个方面介绍了浙江楠目前的研究现状,并在此基础上提出保护对策。

Phoebe chekiangensis C.B.Shang is a rare and endangered plant,and ranked in gradeⅡkey protected wildlife in China.The species distributed narrow range,and the wild natural regeneration ability is poor.In addition,because of its high economic value and development prospects,the species had serious interference and illegal logging.So the population size of P.chekiangensis is believed to be declining and extinctive.This paper summarized the main results of these studies from the aspects of the resource status and geographical distribution,population ecology and biodiversity,seed germination and physiological and biochemical studies,container seedling breeding techniques,afforestation technology,and endangered causes,and put forward some protection strategies for the further study on P.chekiangensis.
