| 摘 要： | 河北省分布有104种蕨类植物,归23科38属.区系地理成分多样,以温带成分占优势,具有过渡性,特有现象明显.和其他地区相比,该区系物种丰富度较落后,与山东区系关系最为密切,与河南、安徽、江苏、浙江关系渐远,而与广西和山西关系最为疏远.以上特点与中国植物区系的分区相吻合,符合所处温暖干旱的气候环境.

| Abstract: | There are 104 pteridophyte species in Hebei province,which belong to 23 families and 38 genera.Its geographical elements are various,and the temperate floristic elements are predominant in this area.The transitional characteristic is obvious.The abundance ration of pteridophyte is relatively low than that in other area.Endemism is remarkable,and 28 species of pteridophyte,making up 27.45% of the total numbers,are endemic to this area.The flora is much more closely related to Shandong than to other regions,and the next come Henan, Anhui,Jiangsu and Zhejiang.While the relations to that in Guangxi and Shanxi are farthest.All mentioned above agreed with the regionalization of Chinese flora and the climate feature of mildness and drought. |
