云南珍稀濒危竹类植物资源现状及保护对策

云南是中国竹类植物分布最丰富的地区，原始属种高度集中，生态类型齐全，全省分布广泛，属种种类丰富，其中53种为珍稀濒危竹种。文章介绍了云南珍稀濒危竹类植物的资源状况和保护现状，提出了保护云南珍稀濒危竹类植物的建议。文章认为应将云南分布面积在2 000 hm²以下的竹种纳入极小种群植物保护之列，并构建极小种群野生植物的种群生态学和保护生物学理论体系；同时保存和扩繁云南竹类极小天然种群，缓解濒危态势。

Present Situation and Protection Countermeasures of Rare and Endangered Bamboo Resources in Yunnan Province

Yunnan boasts most abundant bamboo plants in China. There are highly concentrated primitive genera and species, complete ecological types, wide distribution across the province and rich genera and species, among which 53 species are rare and endangered ones. It is suggested that bamboo species with a distribution area of less than 2 000 ha in Yunnan should be included into minimal-population plant list to be protected, and the theoretical system of population ecology and conservation biology of wild plants in minimal population should be set up. Additionally, the bamboo in extremely small natural population in Yunnan should be preserved and expanded to alleviate the endangered situation.
