中国的几种珍稀濒危冷杉属植物及其地理分布成因的探讨

A preliminary survey on the distribution of rare and endangered plants of Abies in China

概述了 70年代以来中国的几种珍稀濒危冷杉植物的发现及它们残存在特殊小生境中的意义。在野外调查的基础上 ,认为这几种冷杉的生存现状受到严重威胁 ,并指出当前研究和保护工作中存在的问题。综合前人的研究结果对这几种冷杉残遗分布于各局部地点最高山的较高海拔地带 ,且无伴生云杉的分布式样进行了探讨 ,并讨论了冷杉属中生态类型与亲缘关系之间的联系。

A survey of the natural habitats and conservation status of several rare and endangered Abies species discovered in the last two decades from East,South and Southwest of China was made. Based on field investigation,it was found that these species were heavily threatened because of environmental factors and their declined survival ability. A reasonable explanation on the special distribution pattern of these species is proposed based on the literature. According to the result of affinity among these species and other species of Abies,the relationship of the ecology type and affinity was discussed.
