摘要
城市热岛效应对气候、居民身体健康及经济发展产生了深远影响.以哈尔滨市1991-2021年的温度数据为基础,运用Mann-Kendall突变、Sen+Mann-Kendall趋势分析、主成分分析等方法进行研究.结果表明,哈尔滨市热岛效应(UHI)31年来以0.05 ℃/10 a的速度呈波浪型增长,UHI的高值区以城区为主,年均UHI趋势系数呈-0.41～0.19/10 a,阿城区、宾县和哈尔滨站的UHI下降趋势显著.人口密度、年均人口和PM2.5对UHI有正向影响,而风速对UHI的影响则是负向的.此研究结果对哈尔滨市的城市发展具有重要的指导意义.
Abstract
The urban heat island effect has profound impact on climate,physical health and economic development.Based on the temperature data of Harbin City from 1991 to 2021,the study conducts Mann-Kendall mutation,Sen+Mann-Kendall trend analysis,and principal component analysis,etc.The results show that Harbin has city increased at the rate of 0.05 ℃/10 a,the high value area of UHI is mainly the urban area,and the average annual UHI trend coefficient is-0.41～0.19/10 a.The downward trend of UHI in Acheng District,Bin County and Harbin Station is significant.Population density,average annual population and PM2.5 have positive effect on UHI,while wind speed has negative effect on UHI.The results have important guiding significance for the urban development strategy of Harbin City.
