五莲峰市级自然保护区种子植物区系研究

选择样线和样地调查法对五莲峰自然保护区进行系统的标本采集和考察，从科、属、种方面对保护区种子植物区系特征进行研究。结果表明，保护区植物种类丰富，共记录有维管束植物138科、435属、814种；保护区地处云南高原的北部，北邻四川盆地，东临华中植物区系，气候类型总体上或大部分处于亚热带的北缘，植物区系性质由亚热带逐渐过渡到温带；植物区系具有明显的温带性质，同时也表现出与云南热带植物区系的过渡性。另外，大量华中地区常见植物区系成分的出现，表明其在区系起源上与云南其他地区的不同，与华中植物区系间具有较为紧密的联系。

Flora of Seed Plants in Wulianfeng Municipal Nature Reserve

The sampling lines and plot survey methods were used to carry out the systematic specimen collection and investigation on Wulianfeng Nature Reserve,and study the floristic characteristics of seed plants in the reserve from the perspectives of families, genera, and species. The results showed that the reserve had a rich variety of plant species, with a total of 814 species of vascular plants in 435 genera and 138 families; the reserve was located in the northern part of Yunnan plateau, adjacent to the Sichuan basin to the north and the Central China flora to the east; the climate types were generally or mostly located on the northern edge of the subtropical zone, and the nature of the flora was gradually transitioning from the subtropical zone to the temperate zone; the flora had obvious temperate characteristics and also exhibited transitional characteristics with the tropical flora of Yunnan. In addition, the emergence of a large number of common flora components in Central China indicated that the reserve differed from other regions in Yunnan in terms of flora origin and had a close connection with the Central China flora.
