伏牛山南北自然过渡地带植物多样性的特征及其成因分析

Study on the Characteristics and Causes of Formation of Plant Diversity in the Funiushan Transition Region

河南省伏牛山区属于北亚热带向暖温带过渡的地区．该地区植物多样性具有物种丰富、区系成分复杂、起源古老、特有种分布较多等特征．分析表明，生态交错带强烈的空间异质性，特殊的功能和形成历史，以及气候变迁、人类活动的影响是形成该地区植物多样性的主要原因．

The climate of the Funiushan mountain area in Henan Province belongs to the transitional zone between the warm Temperate Zone and the Northern Subtropics.The plant diversity in this region has a few charactreristics,i.e. abounding in species,being complex in the plant flora,originated anciently,abounding in peculiar and rare species,etc.The main causes forming the plant diversity in this area could be concluded that the living space complexity of ecological transitional zone,climate changes,the effections of human life,etc.
