摘要
本文论述了渍害遥感识别的主要标志，通过土壤热惯量、土壤含水量及土壤温度等渍害相关因子的讨论，阐明了渍害遥感识别的基本原理及几种主委方法。由于渍害涉及诸多因素，本文给出了以地学相关分析为基础的渍害判别模型。本研究表明，用遥感方法研究渍害是切实可行的。
In this paper,the main index of identification of waterlog damage usingremote sensing are stated.By the discussion on related factors of waterlog damagesuch as the soil thermal inertia,soil water and soil temperature,the basic princip-les and methods of identification of waterlog damage are suggested.Because thewaterlog damage is related to many factors,the discriminant of waterlog damagewith many variables is developed based on the analysis of geographical relationships. The results show that remote sensing technique can be used to identify the waterlogdamage.
