摘要
根据中国亚热带常绿阔叶林区域的气象资料和植物分布资料，利用Ｋｉｒａ的温暖指数（ＷＩ）和寒冷指数（ＣＩ）及徐文铎从中变化出的湿润指数（ＨＩ）计算了中国亚热带常绿阔叶林１１２个优势种及常见种的水热指标值，分析了树种分布与气候的关系，并将优势种及常见种划分为５个Ｋｉｒａ水热指标分布类群，它们是：Ｇ１低温半湿润型，Ｇ２低温湿润型，Ｇ３低中温湿润型，Ｇ４高中温湿润型，Ｇ５高温湿润型。计算了中国亚热带常绿阔叶林优势种和常见种分布上限的温暖指数和寒冷指数，及一些分布到亚热带北缘的树种的热量指标，通过比较分析探讨了限制常绿阔叶林树种向上和向北分布的寒冷指数特征。
Kira′s warmth index(WI),coldness index(CI)and XU′s humidity index(HI)of 112 dominants and main companions have been calculated.The groups of Kira′s watertemperature distribution of these species have been divided into five.They are G1(Microthermal subhumid type),G2(Microthermal humid type),G3(Micromesothermal humid type),G4(Megamesothermal humid type),G5(Megathermal humid type).The Kira′s watertemperature indexes on the distributional upper limit and north limit of subtropical evergreen broadleaved forest in China have been calculated and discussed.Compared with other conclusions,the characteristics of limiting to upper and north for evergreen broadleaved forest species have been analysed.
