Abstract:

The aim of this research is to describe the types and compositions of plant resources in East Lake Ecotourism Scenic Spot,Wuhan,and the effects of cultivated species on plant compositions.Through field survey,identification of specimens and collection of the data,we recorded 819 species of vascular plants which belong to 453 genera,142 families,including 33 species of pteridophyte(27 genera,17 families),32 species of gymnosperm(32 genera,16 families) and 754 species of angiosperm(410 genera,118 families).According to the characters and uses,these plants were divided into 9 types:ornamental plants,old trees,rare and endangered plants and wildlife under national specialprotection,medicinal plants,timber plants,oil plants,aromatic plants,forage plants and fiber plants.All the plants were analyzed,some representative species were listed,and alien invasive plants were recorded.We also discussed the influence of cultivated species on plants' lifeform and compositions,and the status of plant resources in Wuhan.The results show that the Scenic Spot takes 48.75％ of the total species of Wuhan with only 0.96％ of its area.The proportion of woody plants is relatively low,with that of herbs and vines above the average level of the city.The medicinal plants account for the largest proportion of native plants,while the ornamental plants account for the largest proportion of cultivated plants.There are also some specific proposals to introduce ornamental plants,protect old trees and rare and endangered plants,and control invasive plants.
