摘　　要：河北南部云梦山区苔藓植物种类较为丰富,有244种,隶属36科99属。区系成分以北温带成分为主(52.11%),其次是东亚成分(19.25%),具有明显的温带性质。提出该区系组成属于温暖干旱的北方山地和温暖潮湿的南方山地的中间类型,个别区域小气候环境条件对苔藓植物区系组成具有重要意义的观点。文中对成因进行了初步探讨。As a part of Taihang Mountains,Yunmeng Mountain(37°20′ N,113°54′ E)is 1 520 m above sea level. With a temperate continental monsoon climate,the mountain area belongs to the warm temperate deciduous broad-leaved forest region. This thesis is mostly based on the study of more than 2 000 packages of bryophytes which were mainly collected by the author in Yunmeng Mountain,Hebei Province. Of all these specimens, there are 36 families,99 genera and 244 species(including 17 varieties and 5 formes and 1 subspecies)have been studied and identified. Moreover,it can be seen that Yunmeng Mountain is richer in diversity of bryophytes. The bryofloras are divided into 10 geographical elements. North temperate element makes up the majority,approximating to 52.11% of the entirely known bryoflora,and next belonging to East Asian element,accounting for 19.25%. All temperate elements,not including 14 Endemic to China and 31 Cosmopolitans,add up to 188 species,which take up 88.3% of the entire known bryoflora in Yunmeng Mountain. However,there are only 11 Subtropical and Tropical elements. To all appearances,the bryoflora of Yunmeng Mountain is provided with obvious temperate characters. The author puts forward the standpoint that the bryoflora in Yunmeng Mountain belongs to the middle type between warm and dry northern mountain area and warm and damp southern mountain area. The microclimatic environment has the important influnce to the bryoflora constitutes.
