摘要
采用城市化的多项要素指标,系统考察了太原1980—2009年期间城市化的发展对其城市热岛效应的影响关系,发现城市化的发展是导致城市热岛效应形成和加剧的主要原因。认为:①近30年,太原市郊区的增温率为0.51℃/10a,市区的增温率为0.90℃/10a,热岛强度的增温率为0.39℃/10a,热岛效应不断增强;②各类城市发展指数与城市热岛效应都有很好的相关关系;③太原城郊温差和总人口对数呈线性相关关系,其长期变化相关系数为0.81;④太原城郊温差和城市房屋建筑面积对数呈线性关系,其长期变化相关系数为0.85。
Using several indexes of urbanization,the relationship between urbanization and Urban Heat Island effect(UHI) from 1980 to 2009 in Taiyuan is studied.It is discovered that urbanization was the main reason for the formation and reinforcement of UHI.The conclusions are as following:(1) In recent 30 years,the tendency of temperature in Taiyuan was 0.90 ℃ per 10 years,0.51 ℃ per 10 years in the suburbs;UHI also increased,and the tendency of UHI intensity was 0.39 ℃ per 10 years.(2) There was a significantly positive correlation between urbanization and UHI for all types of indexes.(3) There is a linear correlation between the urban-rural temperature difference and the logarithm of total population logarithm,and the long-term correlative coefficient reached to 0.81.(4) The natural logarithm of housing construction area and the difference were linearly correlated,and the long-term correlative coefficient reached to 0.85.
