景洪市城市热岛效应对城市高温的影响及其防御对策

利用景洪市城郊长期对预测气象资源（１９６４￣１９９４），分析了景洪城市热岛效应及其对城市高温的影响，并提出了防御对策。结果表明，进入８０年代以来，景洪市热岛效应日趋明显，且呈明显的季节性，即干季强于雨季，干季的夜间强于白天，雨季的白天强于夜间；热岛效应不仅增大了市区高温强度，同时增多了高温日数；减缓热岛效应的根本措施是大力发展绿化建设。

THE URBAN HEAT ISLAND EFFECT IN JINGHONG CITY

Based on the fongterm data (1964 ~ 1994) of the comparison observation between the uthan andsubuIban areas of Jinghong City, urheat island effect and its contribution to tuhan high temperathe arestudied. The results indicate that the uran heat island dst of Jibo is gntting mere and un obvious inrecent po. Wth evident Seasonality it is mere strong in the he seaso than in the ndny season, far moresbog at night than at daytime in the dxy seaso, and far un seq at daythe than at night in the mpseaso- The combinahon of urban heat island dst and Ihe ndonal high temperature causes noonly the rising of utban high tempethe but the increase of high tmpthe days. Ih order to ndhpe thewhan hea island effect and to lower urban high temperatri, an dshve way is to strengthen afforeastahon inurban area.
