摘　　要：普朗克黑体辐射定律是遥感类课程教学的重点和难点,本文以定律分析为核心,从数值模拟大气层顶太阳光谱辐照度曲线、卫星传感器光谱响应函数卷积计算、地物行星反射率计算及地表温度反演4个方面入手,对黑体辐射定律理论教学和实践教学内容进行优化设计和教学实现。实践证明,该教学改革不仅可以使学生更容易理解和掌握黑体辐射定律揭示的基本规律,而且以此为基础,能够使学生通过实践加深对地物两大特性(反射特性和热辐射特性)的理解,提高学生对遥感类课程的兴趣。To improve the teaching quality of the Planck law, a series of practice reform contents including spectral irradianee, corresponding spectral functions of satellite sensors, planetary reflectance calculation and temperature retrieval were proposed and achieved. It was proved that these methods could not only make students understand the basic definition of Planek law easily, but also help them to study the two properties （ reflectance and thermal radiation） on land surface. This practice teaching experimental reform would enhance the interest of student in learning remote sensing.
