摘要：

研究旨在了解云南鸡足山种子植物多样性及区系特征，为该地区种子植物多样性评价、资源开发利用及保护提供科学依据。基于2023—2025年鸡足山生物多样性本底调查数据（43条样线、36块样方）及文献资料，采用APG Ⅳ分类系统和吴征镒区系划分标准，分析种子植物科属种组成、区系地理成分及及珍稀濒危资源特征。研究结果显示：（1）共记录种子植物138科656属1637种，其中被子植物占99.45%，裸子植物3科5属9种。（2）区系成分呈现过渡性，科级以热带性成分为主（热带性科/温带性科(R/T)为1.68），属级(R/T=0.79)和种级(R/T=0.23)以温带性成分为主，中国特有种704种(43.02%)，鸡足山特有种1种（窄叶象牙参）。（3）入侵植物种类多达35种(2.14%)，珍稀濒危植物121种，含国家一级保护植物1种（西藏红豆杉）、国家二级保护植物20种、云南省重点保护植物4种、云南省极小种1种。云南鸡足山地区种子植物多样性丰富、区系复杂、特有性显著，是滇西山地植物区系的重要组成部分。本研究可为区域植物资源保育提供科学依据，后续需加强入侵植物防控与珍稀物种就地保护监测。

Abstract:

This study aimed to investigate the seed plant diversity and floristic characteristics of Jizu Mountain in Yunnan, to provide a scientific basis for the assessment, development, utilization, and conservation of seed plant resources in this region. Based on the baseline biodiversity survey data of Jizu Mountain collected from 2023 to 2025 (including 43 transects and 36 quadrats) and relevant literature, the APG IV classification system and Wu Zhengyi’s floristic regionalization criteria were applied to analyze the composition of families, genera, and species of seed plants, their floristic geographical elements, and the characteristics of rare and endangered plant resources. The findings revealed that: (1) a total of 1637 seed plant species belonging to 656 genera and 138 families were recorded, with angiosperms accounting for 99.45% and gymnosperms represented by 9 species in 5 genera and 3 families. (2) The floristic composition showed transitional features: at the family level, tropical elements predominated (tropical families/temperate families, R/T=1.68), while at the genus level (R/T=0.79) and species level (R/T=0.23), temperate elements were dominant. There were 704 Chinese endemic species (43.02%) and one species endemic to Jizu Mountain (Roscoea stenophylla). (3) Invasive plant species numbered 35 (2.14%), and 121 rare and endangered plant species were identified, including one nationally first-class protected plant (Taxus wallichiana), 20 nationally second-class protected plants, four key protected plants of Yunnan Province, and one critically endangered species in Yunnan. The Jizu Mountain region in Yunnan exhibits rich seed plant diversity, complex floristic composition, and significant endemism, serving as an important component of the montane flora in western Yunnan. This study provides a scientific basis for the conservation of regional plant resources. Future efforts should focus on strengthening the prevention and control of invasive plants, as well as enhancing in-situ monitoring and protection of rare species.
