Temperate asian elements , east asian elements and endemic elements to china . the temperate elements , including north temperate elements . old world temperate elements and temperate asian elements take the leading position , including 36 species , approximating to 73 . 47 % of all species 按照每种植物的现代地理分布范围，本研究将河北省苔类植物区系成分划分为6种：世界广布成分、北温带成分、旧世界温带成分、温带亚洲成分、东亚成分和中国特有成分。
The keys to the families , genera and species of hepaticae and anthocerotae in hebei are worked out , and the dissected graphs are pictured . moreover , the chinese name , science name , major reference literatures , collect locations , collector and number of specimen , as well as geographical elements and distribution of every species are narrated explicitly . in the hepaticae - flora of hebei , grimaldiaceae , porellaceae and frullaniuccae arc regarded as dominant , showing obvious temperate - zone character and distinct torrid - zone nature , raising the tropic origion theory of china botany - flora which brought forward by professor z . y . wu 同时，根据标本和资料编制了河北省苔类植物科、属、种检索表，详细记述了每种的中文名、学名、主要参考文献考证、标本采集地、采集人和标本号，在河北省和中国各省区及世界范围的地理分布等，描述了每一种与其相近似种的主要区别点和识别特征，并根据标本和文献对其中54种做了显微绘图。
This thesis taking the lead in systematically studying hepaticae , is a part of the comprehensive research of bryophytes in hebei , which will provide datum for the statistics and analysis of bryophytes along with exploit and utility of plant resources in the province , and will provide the first - hand material for the compilation of the 《 flora bryophytarum hebeiensis 》 本论文针对河北省苔类植物进行研究，是河北省苔藓植物生物多样性研究的一个重要部分，也是编写《河北苔藓植物志》的基础性工作；同时，本研究结果将为本省苔类植物资源的开发利用提供重要依据。
The thesis is principally based on the outdoors investigation and the specimens collected by anther and her colleagues in hebei province from 1995 to 2003 . 55 species ( including subspecies and varieties ) of hepaticae and anthocerotae are recorded for hebei , of 22 genera belonging to 16 families . among them , 5 families , 9 genera and 37 species are newly records to llebei , 4 species are renamed 本研究通过对河北省苔类植物较详尽的野外考察、标本采集、物种鉴定、分类和系统整理，初步确定河北省分布有苔类植物16科， 22属， 55种(包括种下单位) ；其中，发现河北新记录科5科；河北新记录属9属；河北新记录种37种；订正原记录种名4种。
The east asian elements have 10 species , accounting for 20 . 41 % , and among them , 60 % are the sino - japan elements . endemic elements to china has 3 species . 27 species of hepaticae in hebei can be seen in north america , holding 55 . 10 % of total , while 29 species can be seen in europe , holding 59 . 18 % 其中，北温带成分、旧世界温带成分、温带亚洲成分为温带成分，共36种，占总种数的73 . 47 ，是河北省苔类植物区系组成的主体；东亚成分有10种，占总种数的20 . 41 ，而中国?日本成分有6种，占东亚成分的60 ；中国特有成分在河北省有3种，占总种数的6 . 12 。
