为有效保护重庆奉节梅溪河湿地自然保护区维管植物资源,在保护区内开展了维管植物多样性调查与研究。根据野外观测数据处理、采集标本分析、影像资料以及前人工作基础,对保护区内维管植物种类组成、生活型组成、植物区系特点、珍稀保护及经济资源植物进行了统计分析。结果表明,保护区共有维管植物168科629属1 230种,其中分布广、抗逆性强的草本植物达626种。保护区植物区系具有植物类群丰富,区系成分复杂,大科及大属优势明显,区系较为古老,有明显过渡性质,特有属比较丰富等特征。针对目前保护区在植物多样性保护管理工作中存在的主要问题,提出了植物多样性保护的对策。

For the effective protection of vascular plant in Meixihe Wetland Nature Reserve of Fengjie county in Chongqing province,the comprehensive investigation and study was carried out. Based on the field observation data processing,sample analysis,photographic material as well as other researchers' work,this paper calculated and analyzed the features of it which included the vascular plant species compositions,life forms,flora characteristics,rare and protected plants,and economic plants. The analysis results showed that there were 168 families,629 genera and 1 230 species of vascular plants in the nature reserve,including 626 species of widespread,strong resistance herbs. The characteristics of plant flora in the nature reserve possess the complex floristic composition,dominent big families and genus,ancient plant flora,obvious transitivity,abundant endemic genus. According to the existing problems in the protection and management of the wetland nature rreserve,protection countermeasures of plant diversity were put forward.
