三峡地区国家珍稀濒危重点保护药用植物种类分布及区系的研究

Study on Species and Distribution of Flora of National Rare and Endangered Medicinal Plant in the Three Gorges Area

根据《中国植物红皮书》和《国家重点保护野生植物名录》,对分布于三峡地区的国家珍稀濒危保护药用植物进行了调查和统计分析,并探讨了其区系成分及地理分布特征。结果表明,三峡地区有珍稀濒危及国家保护药用植物共计46科81属97种,其药用植物区系垂直分布明显,水平分布间断、交叠;古老孑遗药用植物众多;具有明显的温带性质,喜温暖湿润的山沟和山坡;乔木药用植物所占比例远远大于草本、藤本、灌木、蕨类药用植物;特有及单种属比例较大。

According to the China Plant Red Data Book and National Key Protected Wild Plants, the distribution of the rare and endangered plants and national conservative plants in the Three Gorges area were investigated and statistically analyzed. Its floristic composition and characteristics of geographical distribution were explored. As a result, a total of 97 species of medicinal flora belonging to rare and endangered national protection plants were found in the Three Gorges area. They come from 81 genera of 46 families. Their vertical distribution is obvious and horizontal distribution has discontinuous overlap. There are many ancient relict medicinal plants in the Three Gorges area. These medicinal plants have obvious temperate characteristics, and are easily found at warm and moist ravines and hillsides ; The proportion of tree is much higher than that of herb, vine, shrub and fern. Most of them belong to specific and monotypic genera.
