中文摘要: 利用景洪城郊长期对比观测资料（1964—1994年），研究了景洪城市发展对气候的影响。结果表明，随着城市的发展，城市热岛现象日趋明显，城郊气温、同速差逐年增大，市区降水量、空气湿度、雾日数、日照时数、直接太阳辐射及总辐射减少趋势明显，而散射辐射有所增加，且城市热岛效应具有明显的季节性，呈现干季强于雨季、干季的夜间强于白天、雨季的白天强于夜间。

Abstract:Based on the long term data(1964-1994) of a comparison observation between Jinghong city and rurality ,the effects of development of Jinghong city on climate are studied.The results indicate that with the rapid development of Jinghong city,the urban heat island effect is gradually increasing;the rainfall,air humidity,numbers of fog days,sunshine duration,direct solar radiation and global radiation over the city attenuate remarkably,but the sky radiation is increasing gradually.The urban heat island effect is of seasonality obviously,and iss more obvious in dry season than in rainy season,far more obvious at night than day in dry season,far more obvious at day than night in rainy season.
