摘要: 利用Kira的温暖指标和徐文铎的湿度指标,对东北地区233个气象站,5个树种的分布关系进行探讨.结果表明,东北地区主要树种热量指标分布范围在33.5~93.6℃·月之间,当WI在70℃·月时,将5个树种区分为2个分布范围.湿度分布范围为HI5.9~10.6 mm·℃-1·月-1,以HI7.5℃-1·月-1为界线区分两个分布范围.结合上述水热指标分布值,可将东北地区233个气象站和森林树种划分5个类型:(1)寒温性湿润树种分布类型;(2)温性湿润树种分布类型;(3)暖温性湿润树种分布类型;(4)温性半湿润树种分布类型;(5)暖温性半湿润树种分布类型.并建立了树种地理分布与气候关系的回归模型.

Abstract: Kira's warmth index(WI)and Xu Wenduo's humidity index(HI)were used to stndy their relationships with the distributions of the 53 tree species in 233 weather stations in Northeastern China. The results showsed that the WI range of the main species was from 33.5 to 93.6℃ per month and the HI value was from 5.9 to 10.6 mm·℃-1·month. When the WI value reaches 70℃ per month and the HI value reaches 7.5 mm·℃-1 for per month, the distribution range of 53 species can be divided into two zones. Finally, we divided five urban forest types in Northeastern China: 1)cold-temperate wet forest type, 2)temperate wet forest type, 3)warm-temperate wet forest type, 4)semi-wet temperate forest type, and 5)semi-wet warm-temperate forest type.
