摘要
河南栾川老君山自然保护区位于北亚热带和南暖温带过渡区的伏牛山北坡,植物种类十分丰富,有野生种子植物1509种,隶属于131科606属。对全部种子植物属、优势植物属及优势种的区系分析,显示出该区植物区系以温带成分占优势,具有暖温带植被类型的典型特征。该区植被主要有5个群系纲:工针叶林,Ⅱ落叶阔叶林;Ⅲ山顶矮林;Ⅳ山地灌丛;V山地草甸。落叶阔叶林是该区的地带性植被。作者从地植物学角度,对暖温带南界线的确定提出了见解。
LMNR is located in the transitional region of south warm temperate zone and north subtropics.Plant species in LMNR are very rich—150 wild seed plant species in 606 genera and 131 families. Floristic analyses of all seed plant genera and dominant plant genera and dominant species show that the region is dominated by temperate floristic elements and typically characterized by warm temperature vegetation types. There are 5 main Formation classes of vegetation: Ⅰ. Aciculignosa; Ⅱ. Aestilignosa; Ⅲ. Elfin Forest; Ⅳ. Scrub, y. Pratoherbosa. The Aestilignosa is the zonal vegetation in LMNR.The opinion for determining the south line of the warm temperate zone is put forward from the point of geo-botany.
