摘要
以低纬高原城市昆明市为研究对象 ,通过比较分析 ,得出以下结论 :昆明地区受全球气候变暖影响年平均气温约升高 0 5℃ /a左右 ;由于城市面积扩大导致昆明的室内外气温均升高 ,其中室内气温升高幅度大于室外气温 ,干季大于雨季 ;不论是干季还是雨季 ,城市增温效应与城市建成区面积、城市人口均有较好的相关关系。城市建成区面积增加对平均气温的影响较大 ;而城市人口增加对平均室内气温的影响较大。城市建成区面积每增加 1km2 ,年平均室内气温将升高 0 0 0 5 4℃ ;年平均气温升高 0 0 12℃。而城市人口增加 1万人 ,年平均室内气温升高 0 0 2 5 9℃ ;年平均气温升高 0 0 0 98℃。
The results of the research on the case of Kunming show that the global warming brings about an increase of the average air temperature of around 0 5℃/a.With the expansion of the city,the indoor and the outdoor air temperature rise,the increase of the indoor temperature goes higher than that of the outdoors,the dry seasons exceeds the rainy seasons.The correlativity between the effection of city temperature increase and the urban coverage and urban population is considerable.Urban expansion has considerable effect on the average air temperature while the urban population increase obviously affects the average indoor air temperature.The indoor air temperature goes up 0 0054℃ per 1km 2 increase of urban coverage,the annual average air temperature rises 0 0012℃.On the other hand,the indoov air temperature goes up 0 0259℃ per 10,000 increase of urban population and the annual average air temperature rises 0 0098℃.
