摘要
利用邢台站探空观测资料,分析近32年（1979-2010年）城市化对邢台气温变化的影响,并与该站地面观测资料得出的城市热岛效应相比较。结果表明,通过探空近地层与850 h Pa层气温序列比较得出城市化对年均气温的增暖幅度为0.31℃/10a,贡献率为49.21%;对比城市站与郊区背景站地面观测气温资料得到城市热岛效应导致的增暖幅度为0.18℃/10a,城市化贡献率为35.29%;采用城市站地面观测气温与探空850 h Pa层气温对比得到的城市化增温幅度为0.19℃/10a,分离出的城市化贡献率为37.25%;3种方法计算得出的城市化增温幅度及贡献率各不相同,却一致表明城市化对邢台年、季气温的增暖贡献较为显著。
The influence of urbanization to air temperature of Xingtai City in the recent 32 （ 1979 - 2010） years was analyzed based on the sounding data and compared with the urban heat land effect obtained by the ground observation. The results consisted of four parts. Firstly, by comparing the sounding surface layer data with the sounding 850 hPa temperature series, it is found that the urbanization leads to 0.31 ℃/10a in- crease in the mean annual temperature. The contribution rate is 49.21%. Secondly, by comparing the ground observation data of temperature of urban and rural station, it is found that urban heat land effect leads to 0.18 ℃/10a increase in the mean annual temperature. The city contribution rate is 35.29%. Thirdly, by comparing the air temperature obtained at the urban station ground and the sounding 850 hPa layer, it is found that urbanization leads to 0.19 ℃/10a increase in the mean annual temperature. The isolated city contribution rate is 37.25%. It turns out that urbanization warming rates and its contribution rates calculated in three different ways vary, but the apparent positive contributions of urbanization to annual and seasonal air temperature of Xingtai are in substantial agreement.
