中文摘要: 利用2000年4月至2005年7月的卫星遥感资料,采用Surfer软件分析了咸阳“城市热岛”年际变化及特征。结果表明:利用气象卫星遥感监测城市热岛现象是可行和有效的,咸阳市具有明显的热岛效应,春季是一年中热岛发展最强的季节,热岛效应有明显的日变化,市中心商业区热岛效应最强,并明显受地理环境的影响,其影响范围是咸阳市城区面积的1.63～1.86倍。

Abstract:Satellite data from April 2000 to July 2005 and Surfer software technology are used to analyze the annual variation and the characteristics of “urban heat island” of Xianyang, Shaanxi. The results show that it is feasible and efficient to utilize the remote sensing of meteorological satellite to monitor the phenomenon of urban heat island. There are obvious heat island effects at Xianyang. Spring is the strongest season of heat island effects in a year. The effect has an obvious diurnal variation. The heat island effect at the downtown business district is the strongest, and the effect is obviously affected by geographical environment, with the range of effect as large as 163—186 times of urban area of Xianyang.
