A Preliminary Analysis of the Pteridophyte Flora in Hebei Province, China
摘要/Abstract
对河北省蕨类植物区系进行了初步研究,结果表明:分布有104种蕨类植物,归23科、38属,种类不太丰富;地理成分多样,以温带成分占优势;特有现象明显;与北京关系最为密切,其次为山西、黑龙江,与陕西秦岭、河南鸡公山也有一定联系,与云南独龙江关系疏远.这几个特点与中国植物区系的分区相吻合,符合其所处的温暖干旱的气候环境.
The floristic components of the pteridophyte inHebei province are studied. The results show: There are 104 species pteridophyte belonging to 38 genera in 23 families, the floristic elements are relatively not rich. The geographical elements are varied, the temperate floristic elements are predominant in this area.Endemism is remarkable, 28 species of pteridophyte, which make up 27. 45% of the total numbers, are endemic to this area. The flora is much more closely allied to Beijing than to other regions, and next comes Shanxi and Heilongjiang. All of this supports the regionalization of Chinese flora and its warm and dry climate.
