摘    要:河北省塞罕坝地处森林区向草原区的过渡区域,植物种类丰富,共有种子植物75科318属713种或变种。塞罕坝植物区系的地理成分以北温带分布为主,占全区种子植物属数的47.65%。其次是世界分布和旧世界温带分布,分别占全区种子植物属数的15.41%和14.38%,其它分布的植物属较少。植物生活型以地面芽植物为主,高位芽植物、地上芽植物、地面芽植物、地下芽植物和一年生植物分别占全区种子植物的16.27%、1.54%、40.95%、25.39%和15.85%。通过与周围5个地区的主分量分析,塞罕坝植物区系处在森林区植物区系与草原区植物区系之间,具有明显的过渡性。塞罕坝植物区系与草原区锡林河流域和森林区松山植物区系的关系比较密切。

关 键 词:过渡性  植物区系  生态交错带  塞罕坝

Abstract:Saihanba is located in the forest-steppe ecotone in northern Hebei Province of China.The spermatophytes in Saihanba flora were abundant,which includes 75 families,318 genera and 713 species or varieties.According to the floristic geographic elements in Saihanba flora,the northern temperate,cosmopoltan and palaeo-temperate was to the 47.65%,15.36% and 14.11% of the total 313 spermatophyte genera respectively,while the others were rare.Based on plant life-form,the phanerophytes,chamaephytes,hemicryptophytes,geophytes and therophytes were 16.27%,1.54%,40.95%,25.39% and 15.85% of the total spermatophytes respectively in Saihanba region.Compared with the other five surrounding regions using the principal component method,Saihanba was an obvious forest-steppe transitional flora.The relationships of Saihanba flora with Songshan Mountain flora in the forest zone and Xilinhe River Basin flora in the steppe zone were closer than those with the other region floras.
Keywords:transitional feature  flora  ecotone  Saihanba
