摘要：Betula platyphylla and Populus davidiana forests of the forest\|steppe ecotone in northern Hebei and eastern Inner Mongolia are abundant in plants,which are,at least,35 families,95 genera and 117 species.The plant species decrease and a diversity reduces from east to west in the ecotone because of gradually low precipitation.β diversity index reaches peak at the different limits such as those between the ecotone and the forest,and the steppe,and between the forest meadow and the meadow steppe zone in the ecotone.The plant diversity is closely related to climate,the community organization and succession.
