城市发展对室内外气温影响初探

Effect of Urban Development to Indoor and Outdoor Temperature

本文以昆明市为研究对象。昆明地区受全球气候变暖影响年平均气温约升高 0 4 7℃ /a ;由于城市面积扩大导致昆明的室内外气温均升高 ,城市增温效应在 1 -4月较大 ,5-1 2月较小 ;在相同月份 ,平均室内气温的增温率均大于平均气温 ;城市增温效应与城市建成区面积、城市人口均有较好地相关关系。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。

Influenced by the warming up of the global temperature,the annual average temperature of Kunming rises 0 47℃/a.The expansion of urban areas causes the rise of both indoor and outdoor temperaeure.The effect reaches its maximum between January and April and the minimum between May and December.In the same month,the rise rate of average indoor temperature is higher than the average tmeperature.The urban temperature rise closely is related to the urban coverage,which affects the average temperature the most and the urban population,which affects the average indoor temperature the most.
