摘要
利用华北平原9个气象观测台站1960—2011年地面和850 hPa高空气温资料分析华北平原的城市化变化特征。分析城市化对大中城市增温情况,以及应用高空与地面温度差的方法验证城市化增温的可行性。结果表明:地面与城市化增温速率和幅度均呈现上升趋势。大城市的城市化增温率以及城市化对地面增温的贡献率明显大于中等城市。冬春季是城市化增温作用最为明显的季节。1980—2011年的各台站城市化增温与1960—2011年整个时段相比有所变化。部分台站增温效应趋于增强,另外部分站的增温效应趋于弱化或消失。
The heating effect of urbanization is reflected by the contrast which changes year by year between 9 meteorological stations surface air temperature and 850 hPa temperature in north China plain during 1960-- 2011. The impact of urbanization on urban warming in large and medium-sized cities and evaluate feasibility of this method about the difference in temperature between surface and 850 h Pa temperature is analysed. The results show that the warming rates and amplitudes about ground and urbanization appear increasing trend. The large cities are much bigger at contribute of urbanization to ground temperature change than medium-sized cities. The urbanization in winter and spring has more obvious warming effect than urbanization at any other time of year. Compared with ur- banization warming effect during 1960--2011, warming effect is somewhat different during 1980--2011. Warming effect of some meteorological stations tend to enhance, and others approach to weak or gone.
