摘 要 ：

中条山地处山西暖温带南部,水热条件良好,植物种类丰富,是山西植物多样性最丰富的区域,同时也是亚热带植物区系成分在山西分布最为集中的区域.据调查,中条山共有野生种子植物1287种,分别隶属于525属111科,其中裸子植物9种6属4科,被子植物1278种519属107科.其中国家一级保护植物1种,国家二级保护植物4种,山西省重点保护植物36种.种子植物科、属、种的区系成分复杂多样,特有现象不平衡.科的分布区类型中,世界分布40科,泛热带分布34科,没有中国特有科.属的分布区类型中,温带分布351属,中国特有属12属,反映出该区植物区系的温带性质.种的分布区类型中,中国特有分布最多,共504种,其次是温带亚洲分布和东亚分布,它们是构成中条山森林植被和灌丛植被的建群种和优势种的主要成分.

Abstract:A significant number of wild seed plants are located in the warm temperate zone of the Zhongtiao Mountains,located in southern Shanxi,China. Due to the warm moist climate,this region has the highest plant diversity and richest subtropical flora of Shanxi.Results from long-term research indicate that there are 1287 species of wild seed plants in the Zhongtiao Mountains,belonging to 519 genera and 111 families.Among them,4 families,6 genera,and 9 species belong to Gymnospermae and 107 families,519 genera,and 1278 species belong to Angiospermae.Among the flora， Taxus mairei，falls under the state’ s first level protection，while plants such as and Cercidiphyllum japonicum，Glycine soja，Elaeagnus mollis，and Fraxinus mandschurica fall under second level protection.Moerover，Shanxi provincial level protection exists for Populus purdomii，Ostrya japonica，Quercus spathulata，Pteroceltis tatarinowii，Ulmus lamellosa，Ficus heteromorpha，Euptelea pleiospermum，Lindera glauca，Lindera reflexa，Litsea pungens，Rhodiola rosea，Sinowilsonia henryi，Zanthoxylum planispinum，Toxicodendron vernicifluum，Staphylea bumalda，Staphylea holocarpa，Acer zhongtiaoense，Xanthoceras sorbifolia，Meliosma cuneifolia var. glabriuscula，Meliosma vaitchiorum，Actinidia arguta，Actinidia kolomikta，Idesia polycarpa，Kalopanax septemlobus，Cornus officinalis，Dendrobenthamia japonica var. chinensis，Ceratostigma plumbaginoides，Styrax hemsleyana，Styrax japonica，Styrax odoratissima，Chionanthus retusa，Trachelospermum jasminoides，Callicarpa japonica var. angustata，Kollwitzia ambilis，Codonopsis pilosula，and Platycodon grandiflorum.Analysis of the families，genera，and species，showed that the region’ s floristic elements have high diversity and different endemism of families，genera and species.The Cosmopolitan type was dominant (40 families)，followed by the Pantropic type (34 families).No family was endemic to China.Temperate floristic elements were significant for genera，with 351 belonging to temperate type.Moreover，12 genera were endemic to China，reflecting the characteristics of the temperate zone to the flora.Those genera endemic to China were the dominant types among the flora，followed by Temperate Asia and East Asia elements，respectively.They are the main elements of the constructive and dominant species of dominant vegetation types.
