Abstract:

The karst forests of Junzi Mountain are within the territory of Shizong County in east Yunnan Province, belonging to the vegetation zoning of semi-humid evergreen broadleaf forests and Pinus yunnanensis forests of the mid- and eastern Yunnan Plateaus. These forests are predominantly secondary and typical representatives of the forest remnants in the eastern edge of the zonal vegetation. In order to determine the vegetation types and community characteristics of the karst forests in Junzi Mountain, systematic plot surveys were carried out for species composition, quantitative characteristics and habitat information of all plant communities. Based on analysis of the survey data from 29 plots and the revised vegetation classification system of China, these karst forests could be categorized into 4 vegetation formations, 16 alliances and 27 associations. This paper presents descriptions on the characteristics for each association and provides the original data from all survey plots.
