【摘要】 水松(Glyptostrobuspensilis)被列为国家一级保护植物,主要分布于我国的广东、广西、江西、湖南、福建、四川和云南等省区和越南。根据野外调查、查阅标本和文献,结合水松的化石分布资料,对分布区内水松的生长状况和分布区的自然环境概况进行了分析,讨论了温度、雨量、光照和土壤等生态因子对水松地理分布的影响。导致水松濒危的主要原因有:历史时期气候变迁导致水松分布区大幅度缩小和居群数量剧烈下降;水松对生境要求严格;人为破坏严重。根据水松濒危的原因和现状,建议加强对水松原产地的保护,特别是保护那些遗传多样性高的居群;重视水松居群周围生境的保护;以及采取人工繁殖和进行迁地保护等策略。更多还原

【Abstract】 Glyptostrobus pensilis (Staunt. ex D. Don) Koch, distributed mainly in Guangdong, Guangxi, Jiangxi, Hunan, Fujian, Sichuan, Yunnan and Vietnam, was cat alogued as an endangered species and subjected to first-ranking protection level in China. Based on the field investigation, collections , literatures, and fossil records, the relationships between the growth of G. pe nsilis and its environmental conditions, as well as the impacts ofecological factors, i.e. temperature, rainfall, illumination and soil are discus sed. The causes of threat to G. pensilis are the radical climatic changes in his tory resulted in a great decline of the population and a massive shrinkage of th e distribution range on a large scale; strict requirement for the habitats; and the disturbance from humanactivities. It is proposed that the protection of G. pensilis should be strength en by in situ conservation, especially for the populations with genetically high diversity, by conserving the extant habitats of the species, and by ex situ con servation.更多还原
