福建主要树种的分布与气候条件关系的研究

The Preliminary Study of the Correlation between the Distribution of Main Tree Species and the Climate Factors in Fujian Provines

应用温暖指数和湿度指数定量分析了福建主要树种的分布与水热条件之间的关系 ,米槠、栲树、青冈、木荷等树种是福建广域分布的物种 ,具有较大的 WI值范围 ;赤枝栲的分布区域窄小 ,WI值的分布幅仅达 34.8℃·月 ;红栲、乌莱栲、红鳞蒲桃等南亚热带成分具有较高的 WI值 ,与硬壳桂、黄瑞木、蕈树、甜槠、闽粤栲等典型的中亚热带成分交界的 WI值约为 1 75～ 1

By means of warmth index(WI)and humidity index(HI),the correlation between the distribution of main tree species in Fujian and climate factors were analyzed quantitatively in this paper Castanopsis carlesii,C fargesii,Cyclobalanopsis glauca,Schima superba distribute widely and show wider range of WI With narrow range of WI(34 8 ℃·month),Castanopsis kawakamii shows small distribution zone Some south sub tropical component as Castanopsis hystrix,C uraiana,Syzygium hancei,etc ,which have higher WI values,show obvious division arrange of WI 175～185 ℃·month from that of typical middle sub tropical species as Cryptocarya chingii,Adinandra millettii,Castanopsis eyrei, C fissa,Altingia chinensis,etc
