| 摘 要： | 根据树种的分布资料和气象资料,采用桑斯威特(Thornthwaite)方法计算东北地区50种主要树种的潜在可能蒸散(PE)和湿润指数(IM),利用半峰宽法计算热量指数PE的最适范围,并构建Thornthwaite气候指标与树种分布的地理三维要素(纬度、经度和海拔高度)的回归模型,分析东北地区主要树种水热分布规律。综合潜在可能蒸散(PE)和湿润指数(IM)两个气候指标,将东北地区主要树种划分为寒温湿润型,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、暖温湿润型和暖温潮湿型等8个水热指标类群,并论述了东北地区主要树种的水热分布格局。

| Abstract: | Based on geographical distribution data and the climate data,the Potential evapotranspiration(PE),Moisture index(IM) and optimal range of potential evapotranspiration of 50 main trees species in Northeast China have been calculated by using the Thornthwaite's method and the Half peak width method.Furthermore,the regression model of Thornthwaite's indeices and tree distribution was established,the water-temperature distribution system was also analyzed.According to the PE and IM,main trees in Northeast China were classified into eight types cold-temperate subhumid type,cold-temperate humid type,the middle-temperate arid type,the middle-temperate subhumid type,the middle-temperate humid type,warm-temperate arid type,warm-temperate subhumid type,warm-temperate humid type.Water-temperature distribution pattern of the main trees in Northeast China were discussed. |
