摘    要:对甘肃省若干国家基本/基准站、城市站和乡村站1961—2002年共42年季、年平均温度资料等进行了对比分析。结果表明:城市站和国家基本/基准站比乡村站增温趋势显著。近40多年来城市热岛效应对基本/基准站年平均温度的增温贡献率为18.5%,对城市站年平均温度的增温贡献率为37.6%。季节增温率冬季最大,秋季次之,春夏季最小;城市热岛效应对季节增暖的贡献率则为春季最大,夏季次之,秋冬季最小。

关 键 词:城市热岛效应  温度序列  增温趋势  贡献率

Abstract:Using the data of monthly mean temperature at 38 stations in Gansu Province,the effect of increased urban heat island magnitude on the regional annual and seasonal mean temperature series as constructed based on the national basic/reference stationsand six urban stationsin 1961-2002 was analyzed.It has been found that the trendsof temperature change as calculated using data from national basic/reference and urban stations are generally larger than that of rural stations.The rural stations consist of six \!pure\" countryside stations across the province.The contributions of increased urban heat island magnitude to the trendsof regional mean temperature change calculated based on data from national basic/reference stations and six urban stations are estimated as being 18.5%,and 37.6%,respectively.It is also interesting to note that,on the basis of national basic/reference stations records,maximum warming rate of the regional seasonal mean temperature occurred in wintertime,and maximum urban warming rate occurred in wintertime,but the largest relative contribution of increased urban heat island magnitude to theregional warming rate was in springtime.
Keywords:Urban heat islandeffect  Temperature sequence  Rate of temperature change  Contributive rate
