| 摘 要： | 湖北省兴山县位于三峡库区北岸,这里植物种类丰富,是许多第三纪孑遗植物的避难所。在该县榛子乡白果坪发现一处银杏种群,经过对其进行深入的实地调查,证明这是一片天然银杏种群。进一步从自然环境、古树资源、生长状态、繁殖状况、天然更新、人类活动、化石证据等方面对其进行起源分析,初步推断兴山县很可能是我国银杏原生种群残存地之一。

| Abstract: | Xingshan County is located on the north bank of Three Gorges Reservoir Region in Hubei Province, which has plenty of plant species and is a refuge for the relics of the Tertiary Period. A natural population of the wild Ginkgo biloba has been found in Baiguoping, Zhenzi Township of Xingshan County. Based on the analysis results of natural environment, resources of ancient G. biloba trees, growth condition, reproductive situation, natural regeneration, human activity and the fossil records, the G. biloba population in Xingshan County might be one of the natural wild populations of G. biloba. |
