Abstract

According to field investigation, specimens collection and relevant reference, the floristic elements and areal types of families and genera of Daguishan Provincial Nature Reserve located in Heyuan city of Guangdong province were analyzed. The results showed that: (1) There were 1416 wild vascular plant species including varieties and forma, belonging to 679 genera in 190 families. In which there were 129 species of pteridophytes belonging to 64 genera in 37 families, 7 species of gymnosperms belonging to 5 genera in 5 families and 1280 species of angiosperms belonging to 610 genera in 148 families. The dominant phenomenon in family of seed plants was significant, and the composition in genus was highly dispersed. (2) The flora of vascular plants in this reserve was complex, with a predominantly tropical composition. At family level, there were 8 distribution types and 8 variety-types of seed plants. There were 9 distribution types of pteridophytes. At genus level, there were 14 distribution types and 15 variety-types of seed plants. The pteridophytes belonged to 9 distribution types. (3) Comparing the Daguishan Nature Reserve with three neighboring reserves in Guangdong province, the results showed that Heyuan Daguishan had the highest synthetical index of flora and the second highest phylogenetic differentiation, indicating that the plants in this reserve were relatively rich and should be more strictly protected.

Key words： Daguishan; flora; wild vascular plant
