摘要: 通过对生态环境水热因子的遥感监测回顾,总结出定量地遥感监测土壤水分的方法主要有:微波遥感监测法、热惯量法、作物植被、亮温综合指数法和热红外法等,并对各方法的原理和具体的适用领域做了介绍和比较。

Abstract: The theories and methods of soil moisture monitoring by remote sensing are summarized,after reviewing water and hot index, which can reflect ecology and environment and is one part of it.The results showed that the methods on soil moisture monitoring by remote sensing have microwave remote sensing monitoring , thermal inertia, the composite index of crop vegetation and brightness index, as well as hot infrared monitoring ,etc. Eventually, the principle to every method and concrete suitable field have been described and compared.
