摘　　要：遥感技术的迅猛发展为火山监测提供了无法替代的技术手段 ,探讨火山区热红外遥感监测机理对提高地热异常的监测精度将起到积极的作用。在对地热异常有关因素如 :热辐射、热传导、对流交换等进行深入分析的同时 ,也指出了各种不同类型的噪声干扰着地热异常信息的正常传输 ,并提出了合理解决问题的方法。The rapid development of remote sensing technology provides a good technological approach for volcanic monitoring. Studying the mechanism of thermal infrared remote sensing monitoring play a positive role in boosting the monitoring accuracy for geothermal anomaly. In the process of deeply analyzing the factors related to geothermal anomaly such as thermal radiation, thermal conduction and convention exchange etc., a variety of noises were found to interfere the normal transmission of geothermal anomaly information. Finally author works out a solution to these problems.
