基于遥感的南宁城市热岛效应时空演变分析
Spatio-temporal evolution of urban heat island effect in Nanning based on remote sensing
摘要
Abstract
This paper used remote sensing data such as MODIS and TIRS to calculate the earth surface temperature, heat field intensity, and heat island intensity in the four seasons and the day and night of Nanning city in 2013, respectively, and studied the spatial distribution, the evolution of the four seasons,and changes in day and night of Nanning urban heat island. The results showed that the central heat island center of Nanning is mainly concentrated in Xixiangtang and Jiangnan areas, while in areas with large vegetation covered, such as Xingning, Liangqing, and Qingxiu District, the heat island were relatively weak. The high temperature areas in the daytime were scattered on the north and south sides of the city, while at night, city center had a high temperature. The intensity of heat island during the daytime was much greater than which in the evening, and in summer, the intensity of the heat island was strongest while in winter the heat island was the weakest.关键词
