摘　　要：随着我国空间规划的开展,需要能够掌握城市各地块的人类聚居和工业发展等指数,其中城市地表温度是衡量城市各地人类居住和发展状况一个有效的参考。传统的手段统计分析地表低温宏观性差,且时效性不佳,因此需要一种能够快速分析城市地表气温方法。研究以典型的南方城市——南宁市为例,利用Landsat8的多波段卫星遥感数据,通过热红外辐射到同温黑体辐射定标,快速分析城市地表温度差异,从而获得比较准确的城市地表温度分布图。该研究成果对于未来南宁市空间规划和城市建设等领域,都有重要参考作用。With the development of China’s spatial planning,we need to be able to grasp the index of human settlements and industrial development of each urban plot,in which the urban surface temperature is an effective reference to measure the human living and development status in various parts of the city.The traditional method of statistical analysis of surface low temperature is poor in macroscopicity and timeliness,so it needs a fast method to analyze urban surface temperature.Taking Nanning,a typical southern city,as an example,using landsat8 multi band satellite remote sensing data,through thermal infrared radiation to the same temperature blackbody radiometric calibration,the paper quickly analyzes the difference of urban surface temperature,so as to obtain a more accurate urban surface temperature distribution map.The research results have an important reference for the future of Nanning in the field of spatial planning and urban construction.
