摘　　要：柳州市作为广西最大的工业城市、国家Ⅱ型大城市和中国五大汽车城之一,近年来其城市规模不断扩张,工业化进程不断加速使得城市热岛现象表现得越来越显著,但对柳州市热岛效应研究很少,尤其是多年连续遥感监测研究尚属空白。本文主要研究柳州市区城市热岛效应现状及其影响因素。通过辐射传输方程法反演柳州市近20年地表温度,分析其影响因素,阐明地表温度与城市发展、地形、下垫面、地物光谱的关系。研究结果表明:柳州市热岛效应基本呈“点状→面状→带状”时空演变规律,与城市规模扩大、经济发展加速密切相关;不透水面对热岛效应的促进最强,植被对热岛效应的抑制最有效;对重工业城市热岛效应的研究而言,相较于羟基特征值,铁染特征值可以作为更好的指标。根据柳州市热岛效应的时空演变规律和发展趋势,对城市工业布局和建设规划提出科学合理的建议。Liuzhou is the largest industrial city in Guangxi,also one of the nationalⅡcities and China's five big motor citie,the city scale has been expanding in recent years,industrialization process make the urban heat island phenomena appear more and more significant,but the research of heat island in Liuzhou city is rare,especially research on many years continuous remote sensing monitoring is still blank.This paper mainly studies the urban heat island effect in Liuzhou city and its influencing factors.Using the radiation transfer equation method to invert the LST of Liuzhou city in recent 20 years,the influence factors are analyzed,and the relationship between LST and urban development,topography,underlying surface as well as the ground object spectrum is expounded.The result of research showed that the heat island in Liuzhou city basically shows the spatial-temporal evolution rule as"point shape→plane shape→strip shape",which is closely related to the expansion of urban scale and the acceleration of economic development.The impervious surface promoted the heat island effect most strongly,and vegetation inhibited the heat island effect the most.Compared with the hydroxyl characteristic values,the characteristic values of iron dyeing can be used as a better index for the study of urban heat island in heavy industry cities.According to the temporal and spatial evolution rules and development trend of the heat island effect in Liuzhou,scientific and reasonable suggestions are put forward for urban industrial layout and construction planning.
