摘要
恒山位于山西北部 ,有种子植物 834种 ,隶属于 342属、84科。种子植物属、种区系成分复杂 ,比较分析属、种的区系成分 ,得出恒山以温带成分占优势 ,在诸多温带成分中北温带分布型、旧世界分布型的属数和温带亚洲分布型、东亚分布型的种数占较高百分比。中国特有种的分布亚型以华北分布亚型种数最多 ,其次是西北 -华北 -东北分布亚型和西南 -西北
Heng Mountain,located in the north of Shanxi province,is situat ed between 39°07′~40°48′N latitude and 112°45′~114°05′E,longitude in Shanxi.There are 834 species of seed plants,belonged to 342 genera and 84 families in Heng Mountain.The areal-types of the genera and the species are abundant.Based on their geographical distribution,342 genera are classified into 15 areal-types,834 species are classified 15 areal-types.Analysis of the floristic elements based on genera and species shows that the temperate floristic elements are predominant in Heng Mountain.High percents of North Temperate distribution elements and Old World Temperate distribution elements of genera and Temperate Asia distribution elements and East Asia distribution elements of species show that this area is obvious temperate characteristics of the flora.
