中国龙脑香科植物受胁状况及迁地群落保护探讨

The threatened status and ex situ community conservation approach on Dipterocarpaceae in China

广义的龙脑香科植物是泛热带分布,中国有5属13种,其中1种为引种栽培,仅分布于云南、广西、海南和西藏。许多龙脑香科植物具有很高的经济价值。由于近年来各地森林遭受强度破坏,加之其自身特殊的生物生态学特征和种子生物学特性,大多数种类的生存受到严重威胁。该文主要介绍中国龙脑香科植物目前的受威胁状况、具体保护研究工作及其不足,并提出了进行迁地群落建设的保护策略。

Dipterocarpaceae plants are generally pantropical. There are 5 genrea and 13 species in China and 1 species belonge to the introduced and cultivated,only distributing in Yunnan,Guangxi,Hainan,and Tibet. Many Dipterocarpaceae plants are of high economic values. In recent years,most species are seriously threatened,due to intense destruction of forests and their own special ecological and seed biological characteristics. The article mainly introduces the present threatened situation,conservation research and its deficiency of Chinese Dipterocarpaceae plants. Based on the collection of references on Dipterocarpaceae plants and generalization of former ex situ conservation research,many ex situ community conservation suggestions are put forward,which is aimed to provide basic information and viable conservation strategies for Dipterocarpaceae plants.
