A Study on the Seed Plant Flora of Nanshan Natural Secondary Forest in Shenzhen City

There are 247 seed plants in Nanshan flora of natural secondary forest, belonging to 184 genera of 78 families. The result of research showed that the floral composition was dominated by the tropical subtropical composition, the dominant families were obvious, the genera which had many species were few, the proportion of genera which had one species were comparatively great, and the endemic species were few. Owing to the human activity, the vegetation has been partly destroyed. The protection measures should be taken immediately to restore vegetation.
