| 摘 要： | 根据东北地区树种分布资料和气象资料,计算了东北地区50种主要树种的Kira温暖指数(WI)、温暖指数的全范围和最适范围以及徐文铎提出的湿度指数(HI)。建立了东北地区气候因子与树种地理分布的回归模型,并对气候因素与树种地理分布的相关关系进行了分析。综合50种主要树种的水热指标值,将其划分为寒温湿润型,寒温潮湿型,中温耐旱型,中温湿润型,中温潮湿型,暖温耐旱型和暖温湿润型7个Kira水热指标分布类群,论述了东北地区主要树种沿热量和水分梯度的分布格局。

| Abstract: | Based on the geographical distribution and climate data of main trees in Northeast China,the Kira's warmth index(WI),warmth index's full range,warmth index's optimal range and Xu Wenduo's humidity index(HI) have been calculated.According to the regression model of the northeast climatic factors and the geographical distribution of species,the relationship between climatic factors and species geographic distribution was analyzed.With the water-temperature distribution of 50 tree species in Northeast China,these species are classified into seven types,which are microthermal subhumid type,micro-thermal humid type,mesothermal arid type,mesothermal subhumid type,mesothermal humid type,megathermal arid type,megathermal subhumid type. |
