摘要:
对山西省苔藓植物区系进行了统计分析,结果表明,现已知山西省苔藓植物共52科、150属、430种(含10变种1亚种1变型),优势科(9种以上)有11科,优势属(5种以上)有21属,其中第一大科为丛藓科(Pottiaceae),含26属、107种,扭口藓属(Barbula)为第一大属,含25种。分析区系成分可知,山西省苔藓植物包括8个类型,其中以北温带分布类型最占优势(222种,占总种数的56.21%),其次为东亚分布类型(63种,占总种数的15.95%),表明山西省苔藓植物区系具有明显的温带性质。

Abstract:
Shanxi Province lies in North China(approximately 34°34′-40°45′N,110°5′-114°32′E).So far 430 taxa,of bryophytes belonging to 52 families,150 genera were identified.There are 11 families which include more than 9 species and there are 21 predominant genera which include more than 5 species.An analysis of phytogeographical elements in the area is also given.The bryoflora can be divided into 8 geographical elements in Shanxi Province.The majority is Northern Temperate elements(222 species),accounting for 56.21% of total number.The second is Eastern Asia elements(63 species),approximately 15.95%.It is showed that the bryophyte flora of Shanxi Province is of obvious temperate characters.Though a number of researches have been made,much of it still remains to be explored.
