| 摘 要： | 文章利用１９９２年春、夏、秋、冬四季６个时相的ＮＯＡＡ－１１／ＡＶＨＲＲ资料，在与上海区域行政图（边界以乡为单位）进行几何精度纠正的基础上，通过图象增强处理和多通道信息组合，提取上海市区和浦东新区的热力场分布特征，并用直接对比法，建立亮温。气温的相关关系，取得较好的效果。据上海温度分布图象分析，新区的两个热中心与工业群体区、建筑群体区相对应；市区的３个热中心与商业经济密集区及工业群体区相对应。

| Abstract: | Six temporal NOAA-11/AVHRR data covered four seasons in Pudong New Area ofShanghai are selected to establish the relationship between the bright temperature andthe real temperature.Because the meteo-satellite gets a lot of time phase images covered a large regionand has well synchronism and high point density,it can be used to analyze urban heatfield not only in total scene,but also in local inside structure. First, the NOAA imagesare matched for Shanghai Municipal Administration Map using the geometric accuratecorrection method-Second,with the help of image enhancements and the multi-channelinformation combination, the heat distribution characteristics of the urban districts of Shanghai and Pudong New Area are obtained. At last, by using the direct contrastmethod,the relationships between the bright temperature and the real temperature areestablished. It is shown from- the image analysis of temperature distribution that two heatcenters in Pudong New Area correspond to industrial area and group building area,threeheat centers in urban districts correspond to commercial, residential and industrialareas. |
