对长江三峡库区的乌冈栎林、匙叶栎林和刺叶栎林的植物群落结构与组成以及生态环境进行了初步研究。表明它们属于硬叶常绿阔叶林的范畴 ,属于干旱植被的一种类型 ,并与典型的干旱植被有着一定的联系。其植被的形成是对特殊的生态环境长期适应的结果 ,是季节性干旱和长时间寒冷生境条件下生长发育的一种森林植被 ,表现出明显的生态环境脆弱性。
The structure, composition and ecological environment of plant communities in the oak, oak and oak forests in the Three Gorges Reservoir Area of the Yangtze River were studied. This indicates that they belong to the category of hard leaf evergreen broad-leaved forest and belong to a type of arid vegetation, and have some connection with typical dry vegetation. The formation of vegetation is the result of long-term adaptation to special ecological environment. It is a kind of forest vegetation which grows and develops under the condition of seasonal drought and prolonged cold habitat, showing obvious ecological and environmental vulnerability.
