摘　　要：对河南省焦作市太行山区植物物种进行了实地考察、分析。结果表明,本区共有维管植物1 874种(含变种、亚种),其中蕨类植物25科、54属、160种,裸子植物5科、6属、10种,被子植物125科、656属、1 704种;本区植物涵盖15个分布区类型,科的区系类型以世界成分和热带成分为主,属、种的区系具明显的温带性质,科、属、种的R/T值分别为1.35、0.37、0.16;区系起源古老,存在较多的珍稀濒危植物;本区植物的区系地理性质与小秦岭自然保护区最相似,且5个地区的R/T值符合植物地理分布规律。该区所呈现出的区系特点,与该地成陆历史悠久,地貌多样,且位于暖温带与温带的南北过渡地带有关。Based on the fieldwork in Taihang Mountain area of Jiaozuo,the composition and distribution types of tracheophyte in this area are analyzed. The results indicate that： 1874 species representing 716 genera in 155 families of vascular plants are found in total. Among them,160 species of ferns,10 species of gymnosperms,1 704 species of angiosperms belong to 25 genera in 54 families,5genera in 6 families,125 genera in 656 families,respectively. These plants cover 15 areal types,the major type at family level is cosmopolitan and tropical distribution,the major type on genera and species level is temperate type. The R / T of family level,genera level,and species level is 1. 35,0. 37,and 0. 16 respectively. The flora is obviously temperate. Because of the ancient flora origin,there are a lot of rare and endangered plants. The geographical nature of Taihang Mountain in Jiaozuo is similar to that of Xiaoqinling Nature Reserve,and the R / T of five regions conforms to the distribution of the plant. The floristic characteristics of this area is connected with the fact that the land has been formed for a long time,it and that has varied types of landform,with especially transitional character from north to south.
