| 摘 要： | 选取陕西关中地区12个大、小城市,1970—2009年逐月平均最高、最低和平均气温资料进行不同季节的城市热岛效应分析,对描述热岛效应的热岛强度指标进行研究,并提出以华县站为对比站的改进型温度差直线趋势作为关中城市群热岛强度衡量指标。该指标既消除了局地气候变化影响又剔除了个别小城市增温速率过快的影响。计算结果发现：无论城市规模大小,关中城市群一年四季都存在热岛效应。热岛强度冬春季强,夏秋季弱。大城市的热岛强度无论季节或年增加幅度均比小城市大。

| Abstract: | Based on the monthly average maximum,minimum,mean temperature data from 1970 to 2009 from weather stations and surrounding weather stations in city groups of Guanzhong of Shan'xi Province,the characteristics of urban heat island(UHI) were analyzed.By analyzing the research to find a new way to study the UHI in city groups of Guanzhong of Shan'xi province.Use the Huaxian' temperature is the only suburbs' temperature to compare with other cities' temperature.The way not only eliminates the local effects of cl... |
