西双版纳竹类种质资源、利用和迁地保护(英文)

This paper describes the geographical distribution, utilization, cultural value and ex-situ conservation of bamboo resources in Xishuangbanna, Yunan Province, China. Sixty species of bamboo in 19 genera are recorded in Xishuangbanna. The area of natural bamboo forest is 14319 ha, accounting for 5.92% of whole area of Xishuangbanna. The abundant resource of bamboo plays an important role in the economics and culture of national minorities in Xishuangbanna. Xishuangbanna Tropic Botanic Garden, Chinese Academy of Sciences （CAS）, started to introduce bamboo species in 1961 and established the ex-situ conservation reserve （8 ha） of bamboo in 1981. Up to now, 211 species in 27 genera collected from tropic and sub-tropic of China and South-east Asia have been planted in the bamboo reserve, of which 11 species have bloomed and seeded, and their seeds were cultivated in Xishuangbanna Tropical Botanic Gardens, CAS, China.

西双版纳境内自然分布竹类资源19属60种,天然竹林面积14317hm2,占西双版纳总面积的5.92%。最为丰富的竹类资源在西双版纳的社会经济和民族文化扮演重要角色。中国科学院西双版纳热带植物园从20世纪60年代初就开始进行竹类资源的种类、分布、人工栽培与利用以及迁地保护等方面研究,在1981年建立了一个面积为8hm2竹类资源迁地保护区。到目前为止,已从中国热带、亚热带地区和东南亚国家收集保存竹类资源27属211种,现已有11种竹开花结果,用其种子繁殖育苗并栽培在同一区内,长势较好。本文通过对西双版纳竹类资源的多样性、利用和保护状况的研究,旨在引起人们对西双版纳竹类资源的永续利用和保护的重视。图1表2参7。
