滇中石灰岩山地维管植物物种组成及生态适应性分析

Analysis on the species composition and ecological adaptation of vascular plants in the limestone mountains of central Yunnan

通过近年来在滇中地区的野外植物资源调查,根据6个样地的数据和文献资料,总结了滇中石灰岩山地维管植物的物种组成,并比较分析了其生态适应性,以期初步揭示这一区域的植物区系特征,并为石漠化治理提供借鉴。维管植物总计有76科188属263种,其中乔木22种,灌木69种,草本150种,藤本22种,专性分布于石灰岩生境的有16种。

Based on plant resource field investigation of central Yunnan in recent years, according to the data of six sample plots and literature, we summarize the composition of vascular plant species, and comparatively analyze its ecological adaptability, in order to reveal the regional floristic characteristics and provide guidance for rocky desertification controlling. There are 76 families, 190 genera and 265 species of vascular plants, of which 22 species are arbor, 69 areshrubs, 149 are herbs, 22 are lianas, and 16 species are only distributed in the limestone habitat.
