摘要
基于气象台站、MODIS、DMSP/OLS卫星遥感等数据信息,对2003—2016年雄安新区地表温度的时空变化特征进行定量分析。结果表明,该地区平均地表温度变化范围为13~17℃,空间分布不均,中心城区与周边地区的温度偏差至少1.5℃。其中,雄县、安新和容城等城镇化较高地区的地温处于14.5~17℃,且面积呈逐年扩大趋势,年均扩张速率为29.5 km2/a。地表温度总体上升趋势显著,平均增速范围为0.07~0.13℃/a,高于北方地区的年平均地温增速水平。整体上,受近年来城市化进程的影响,雄安新区的城市热岛效应正呈现出由弱变强的增长趋势。
Based on digital information from meteorological stations,MODIS and DMSP/OLS remote sensing satellites,the time-space variations of the ground surface temperature(GST)in Xiong′an New Area during 2003-2006 are ana⁃lyzed.Results show that the mean GST ranges from 13 to 17℃,with a non-uniform space distribution where the tempera⁃ture difference between the urban and rural areas is at least 1.5℃.The GST in Xiong′an and Rongcheng areas with a high urbanization level is 14.5-17.0℃and is expanding gradually with the speed of 29.5 km2/a.For the whole area,the mean GST is growing up with the speed of 0.07-0.13℃/a,higher than the average level in the Northern China.General⁃ly,the urban heat island effect in Xiong′an New Area is becoming more severe,which is mainly caused by rapid local ur⁃banization in recent years.
