掌握混沟植被群落特征可为森林群落演替规律及内在机制的研究和暖温带地区地带性森林的保护提供参考。采取样线和样方调查法,通过重要值确定群落类型,系统分析历山国家级自然保护区混沟地区的物种组成、植物区系和群落特征,以及垂直分布、坡向分布等植被群落空间格局。结果表明:1)历山国家级自然保护区混沟地区共记录到维管植物443种,隶属于93科267属;2)种子植物科的分布区划分为10个类型,属划分为14个类型,种划分为11个类型;植被划分为6个植被型组、9个植被型、28个群系、43个群丛;3)地带性植被是暖温带阔叶林,零星分布有亚热带成分的植物群落。

Mastering the characteristics of vegetation communities in the Hungou area can provide a reference for the deeper research into forest community succession law and internal mechanism in Hungou,and provide a scientific basis for the study of the protection of zonal forest in the warm temperate zone.Using the method of route survey and sample survey,the community types were determined by important values.The species composition,floristic characteristics and community characteristics of the Hungou area in Lishan National Nature Reserve were studied and systematically analyzed and the spatial pattern of vegetation communities,such as vertical distribution and slope distribution was analyzed.The results showed that:1)There were 443 species of vascular plants in the study area,belonging to 93 families and 267 genera.2)The distribution types of seed plant families can be divided into 10 types.The distribution types of genera can be divided into 14 types,and the distribution types of species can be divided into 11 types.It is divided into 6 groups of vegetation type,9 vegetation types,28 formations and 43 associations.3)Zonal vegetation is broad-leaved forest in the warm temperate zone,but plant communities with subtropical components are scattered.The research results have preliminarily grasped the characteristics of vegetation communities in the Hungou area.
