滇东菌子山喀斯特森林的植被类型及其特征

Vegetation types and their characteristics in karst forests of Junzi Mountain in East Yunnan,China

菌子山喀斯特森林区位于云南东部师宗县,在植被区划上属滇中、滇东高原半湿润常绿阔叶林与云南松(Pinus yunnanensis)林区。该片森林以次生林为主,是这一植被区东部边缘残留森林的典型代表。为揭示菌子山喀斯特森林类型组成及其群落特征,该研究对该森林区开展了系统的样方调查,记录了群落的物种组成、数量特征、生境信息等。通过对29个样方的调查数据的分析,基于群落学-生态学分类原则和最新的中国植被分类系统修订方案,该喀斯特森林可划分为4个植被型,16个群系和27个群丛。该研究对每个群丛的特征进行了描述,提供了所有样方的原始数据。

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.
