摘要
利用1986—2005年哈尔滨市区、郊区的年均气温资料以及哈尔滨市发展强度资料,分析了哈尔滨近20a来城市发展与热岛效应的关系。结果表明:哈尔滨市发展强度指标与热岛效应之间具有显著的正相关关系,工业生产总值、建成区面积、全年用电量、公共交通实有车辆、年末实有道路面积、全年供水量是使哈尔滨市产生热岛效应的主要因子。综合城市发展指数与哈尔滨市年热岛强度指数的相关系数为0.72,二者拟合曲线初具环境库兹涅茨曲线特征。
By using the temperature data at an urban station and three suburban stations and the urban development statistical data in Harbin from 1986 to 2005, the relationship between urban development and heat island effect was analyzed for the past 20 years. The main conclusions are summarized as follows： there was a positive correlation between urban development and heat island intensity in Harbin. The main contributive factors to heat island effect were annual industrial GDP, built-up area, annual power consumption, public transport vehicles, road areas and annual water consumption. The correlation coefficient between synthesized urban development index and annual heat island intensity was 0.72, significant at the 0.01 significance level, and their fit curve generally showed the characteristic of Environmental Kuznets Curve.
