江汉平原渍害田热力学特性及其遥感研究
- THE THERMODYNAMIC CHARACTERS OF WATERLOGGING FIELD IN JIANGHAN PLAIN AND PUSSIBILITY OF REMOTE-SENSING APPLICATION
- 摘要：讨论了渍害田的温度、热惯量等热力学特性。根据江汉平原的实例资料, 给出了渍害田温度的时空分布特征和热惯量的两种计算模型。探讨了渍害田光谱特性与卫星接收到的辐射量之间的关系。论证了用遥感方法研究渍害田的可能性, 并指出了实现这种研究的途径和方法。
- Abstract：In this paper,the thermodynamic characters of water logging field suchas temperature and thermal inertia are discussed. Based on the observationaldata collected from Jianghan Plain,the temporal and spatial distribution fun-ction of temperature of waterlogging field is given and two calculation mo-dels of thermal inertia of waterlogging field are developed. The relationshipsbetween the spectral characters and the radiation received by sensors on satel-lite are discussed, and the possibility of remote sensing application in wa terlogging field study is demonstrated, and the ways in which the study canbe conducted are suggested.
