新宾县森林的自然分布,以木奇乡为界,东部属长白植物区系,西部有华北植物区系千山段植物侵入。据调查树种有35科,75属,175种。林木生育与气候(主要是光、温、水)息息相关。各地不同气候类型构成不同的树种组成和林分,并决定着不同生产潜力。本文从区域性特点出发,试述生态因子同林木分布间的关系,并展示发展生产具有的巨大潜力。一、新宾县植物区系划分的生态依据 (一)东西两区系的地理界线从清(原)新(宾)两县的界山—龙岗
Xinbin County, the natural distribution of forests to the odd woody community as the boundary, the eastern part of Changbai flora, the western part of the Qianshan flora of North China intrusion. According to the survey there are 35 families, 75 genera and 175 species. Tree growth and climate (mainly light, temperature, water) are closely related. Different types of climate constitute different tree species composition and stand, and determine the different production potential. Based on the regional characteristics, this paper tries to discuss the relationship between ecological factors and the distribution of trees and show the great potential of developing production. First, the ecological basis for the division of flora in Xinbin County (a) the geographical boundaries between eastern and western two lines from the Qing (original) new (Bin) two counties in the mountain - Longgang
