该文依据“三峡库区植物数据库”，对库区的珍稀濒危植物进行了研究。结果表明：库区有珍稀濒危植物４４种，其中濒危的６种，渐危的２０种，稀有的１８种；半数以上的种类隶属于起源古老的科，反映出该地区珍稀濒危植物的主老性；受淹没影响最大的兴山、巴东、宜昌、巫山４县市拥有近２／３的珍稀濒危植物种次，成为重点保护区域；三峡水库虽不会导致植物物种的消灭，但将直接淹没荷叶铁线蕨的主要原产地和长瓣短柱茶的部分野生生境。
Based on the “Three Gorges Reservoir Database”, this paper studied the rare and endangered plants in the reservoir area. The results showed that there are 44 rare and endangered plants in the reservoir area, of which 6 are endangered, 20 are rare and 18 are rare.
