云南竹亚科植物的“五个多样性”及其与周边区域的联系

Study on the bamboos diversity and its conservation in Yunnan, China

云南是世界竹亚科植物种类最多、生态类型和天然竹林最丰富的地区之一。本文对云南竹类植物多样性的5个特征,即珍稀种质资源多样性、区系地理成分多样性、天然竹林类型多样性、生态竹林景观多样性、少数民族竹文化多样性进行了系统研究,论述了与周边地区(东南亚、南亚次大陆、珠江流域、长江流域和喜马拉雅山区等)的密切联系,提出了加强云南竹类植物多样性保护和利用的相关措施。作者建议将开发利用价值较高的世界性珍稀濒危竹种列入我国保护植物名录,由国家自然科学基金立项资助进行专题研究,并给予专项资金在全国建成三大种质资源引种保存和试验研究基地。

That the Bamboo Resources of Yunnan is very rich and wide ranging due to the particular geographical place and complicated habitat. The bamboo resources of Yunnan are the most abundant in both species, ecological typus, and natural bamboo forests in the world. In this paper, the characteristics of bamboos diversity, relationship between Yunnan and its surrounding area, inside relationship from Yunnan bamboos diversity have been discussed. There are 5 characteristics in bamboos diversity of Yunnan. as well as valuable and rare germ plasm,floristic composition, natural bamboo forests, ecological landscape,bamboo culture of national minority. The bamboos diversity of Yunnan is closely linked with that of its periphery area, include Southeast Asia, the subcontinent of South Asia, Zhujiang River Valley, China, Yangtse River Valley, China, and Himalayas. The authors suggest that three germplasm bases would be invested by the govenment.
