滇东南老君山自然保护区蕨类植物的生态类型

The Ecological Types of Pteridophytes in Laojun Mountanin Natuer Reserve,Southeast Yunnan

在分类和区系的基础上 ,对滇东南老君山自然保护区蕨类植物的生态类型进行研究 .根据各个生态因子的生态作用 ,可将老君山自然保护区蕨类植物的生态类型划分为阳性植物、阴性植物、耐阴植物、高温植物、亚高温植物、中温植物、旱生植物、中生植物、湿生植物、水生植物、附生植物、土生植物、石生植物等 .最后初步得出老君山自然保护区蕨类植物的生态特征 :(1 )生态类型多样 ;(2 )阴性植物、亚高温植物和中生植物种类多 ;(3)附生植物种类所占比例大 ;(4 )中温植物。

This paper deals with the ecological types of pteridophytes from the Laojun Mountanin Nature Reserve,Southeast Yunnan,based on taxonomic and floristic studies.The pteridophytes from the Laojun Mountanin Nature Reserve,Southeast Yunnan,can be divided into 13 ecological types separately according to the effects of ecological factors,that is heliophytes,sciophytes,tolerophytes,megatherm,submegatherm,mesotherm,xerophytes,mesophytes,hygrophytes,hydrophytes,epiphytes,terraphytes and lithophytes. Finally,the ecological features of Pteridophytes from the Laojun Mountanin Nature Reserve are:(1)Diversified ecological type;(2)Rich in the species of sciophytes,submegatherm and mesophytes;(3)High proportion of the species of epiphytes;(4)Few proportion of the species of mesotherm,xerophytes and lithophytes.
