Diversity Analysis of Flora in Secondary Growth of Forest in Fuyang, Hangzhou

Abstract

On the basis of a comprehensive survey and data collation, the floristic characteristics of secondary forests in Fuyang District, Hangzhou were studied, and the level of biodiversity in the area was assessed by investigating the plant species, their numbers and their distribution. The results showed that a total of 267 species of vascular plants belonging to 77 families and 165 genera were identified within the geographical scope of this study. In terms of specifics, ferns included 6 families, 6 genera and 8 species, while gymnosperms covered 6 families, 11 genera and 12 species, and angiosperms contained 65 families, 148 genera and 247 species. In the classification of families, 20 families contained only a single species and 42 genera also contained only a single species. In terms of family composition, Lauraceae and Rosaceae were prominent with 20 and 21 species, respectively. In the classification of genera, Holly (Ilex) was the most species-rich genus with 10 species count. The ferns in the study area are mainly characterized by a cosmopolitan distribution, an Old World tropical distribution, and an interrupted distribution between tropical Asia and tropical America. Seed plants have a diverse range of distribution areas, mainly in the tropics and temperate zones. The main vegetation types in the study area include warm coniferous forests, evergreen deciduous broadleaf mixed forests, evergreen broadleaf forests, bamboo forests, and scrub grasslands.
