| 摘 要： | 采用航天遥感技术方法对广东珠江口区域大气污染物分布进行宏观的面状调查，分析了卫星遥感像元信息构成的物理机制。通过实验证明，像元信息可概化为土壤、植被、水体等基本信息类型的线性集合与污染气体信息的简单叠加，用多波段卫星遥感数据，经公式计算，从美国陆地卫星5号的数据直接定量提取区域大气污染气体累加浓度的信息表明，该污染信息将对珠江口大气污染状况有较客观、形象地再现。

| Abstract: | Remote-sensing technology was applied to investigate the air pollution concentration distribution in the area of Pearl mouth. Based on the analysis of satellite physical mechanism of remote-sensing information, a model for remote-sensing identification and management of emitted gas has been established in order to extract the information of pollution diffusion, then the data of remote-sensing were used to establish equations and decomposed pixel information. It is the first time in China to get the accumulative concentration information from TM satellite data. The image showed pollution distribution and impact area clearly. |
