摘　　要：采用典型样方法和典型线路法,于2019年7月和2019年9月在剑湖湿地自然保护区开展陆地和湿地植物2次调查,对该区进行了科属种的统计、次生植物的划分和统计、分布区类型的研究以及区系特征的评价。结果表明:剑湖湿地自然保护区有种子植物110科353属623种,其中,裸子植物2科3属3种,被子植物108科350属620种;有中国特有属8属、中国特有种205种,其中云南特有种36种;有次生植物168种,占保护区种子植物623种的26.97%。植物区系成分以温带类型为主,由种到科温带性质逐级降低,热带性质逐级升高。因此,剑湖自然保护区植物物种丰富度较低、特有率低、植物区系次生度较高。其原因主要是气候干燥、生境单一和人为干扰严重。The typical quadrats and typical routes investigation methods have been carried out for the land plant vegetation and wetland plant vegetation of Jianhu Wetland Nature Reserve in July 2019 and September2019. The statistics of the families, genera and species;the division and statistics of the secondary plant and the distribution types and floristic characteristics of the area and an appraisal has been made. The result shows there are 623 species seed plants, belonging to 353 genera and 110 families, including 3 species, 3 genera and 2 families of gymnosperms, and the 620 species of angiosperms belonging to 350 genera and 108 families. There are 8 genera and 205 species of Chinese endemic seed plants, 36 species of Yunnan Provincial endemic plants. There are 168 species of secondary plants, takes the ratio of 26.97% among the 623 species seed plants in the nature reserve. All the species of the seed plants mainly distribute in the temperate zone, and the temperature component is low gradually by the species, genera and families while the tropic components is higher gradually on the contrary.According to the research, the species richness and the endemic ratio is low and the floristic secondary index is higher. The main reasons caused the above floristic characteristics are the dry climate, the single habitat and serious human disturbance.
