摘要/Abstract

摘要： 分析了2003-2006年南宁市区和郊区的10个自动气象观测站气象资料，结果表明，南宁市区的热岛强度（UHI）具有明显的日、月和季节变化。一般来说，南宁市UHI夜间＞UHI白天；UHI干季（9月至翌年1月）＞UHI雨季（2-8月）；UHI秋季＞UHI夏季。用不同的温度指标计算出的UHI略有不同：UHI最低气温为1.43℃、UHI平均气温为0.94℃、UHI最高气温为0.28℃。利用灰色关联度分析法分析了影响南宁城市热岛效应的主要气象因子，发现在风速小、相对湿度小的时候热岛效应强。

Abstract: An analysis was performed on the meteorological data from 10 auto-weather stations located in the urban and suburban areas of Nanning City from 2003 to 2006. It shows that urban heat-island intensity (UHI) in Nanning City had evident variations on daily, monthly and seasonal scales. On average, the UHI was larger for night-time, dry season (September-next January) and autumn than that for day-time, wet season (February-August) and summer, respectively. Using different temperatures as indexes for HUI resulted in slight difference: HUIs for the minimum, maximum and mean temperature over 2003-2006 were 1.43℃, 0.94℃, and 0.28℃, respectively. According to the gray analysis of the meteorological factors for HUI effect, small wind speed and small relative humidity may result in a strong UHI in Nanning City.
