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。
概述瞭70年代以來中國的幾種珍稀瀕危冷杉植物的髮現及它們殘存在特殊小生境中的意義。在野外調查的基礎上,認為這幾種冷杉的生存現狀受到嚴重威脅,併指齣噹前研究和保護工作中存在的問題。綜閤前人的研究結果對這幾種冷杉殘遺分佈于各跼部地點最高山的較高海拔地帶,且無伴生雲杉的分佈式樣進行瞭探討,併討論瞭冷杉屬中生態類型與親緣關繫之間的聯繫。

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.
