Woody Plants Diversity in the Lakeside Areas of Lakes and Wetlands in Yunnan Plateau

Purpose Planting green plants is essential for ecological restoration in lakeside areas. The diversity of woody plants was discussed in this paper.

Method Woody plants were investigated in 149 sampling sites with 1.0 hm² in lakeside areas of 24 lakes and wetlands all over Yunnan Province, the growth, source and cultivation/wild types of these plants were classified, the richness, evenness and Shannon-Wiener index were calculated, and effects of altitude, longitude and latitude, and lake area on woody plant diversity were analyzed.

Result A total of 250 species of woody plants belonging to 155 genera and 72 families were recorded. Of which, 126 species of trees were dominant (50.4%), with 108 species of shrubs (43.2%) and 16 species of vines (6.4%); 193 were native species (77.2%) and 57 (22.8%) are aliens; 206 are cultivated species (82.4%) and 44 wild species.

Conclusion The narrow belts of lakeside areas of lakes and wetlands in Yunnan Province are rich in the germplasm resources of woody plants (especially trees), which are characterized by local and cultivated species. Alien woody plants are spreading out from the central Yunnan areas or from areas with great human interference. It is necessary to control and reduce the risk of species invasion.
