摘　　要：土壤水分是陆地表面参数化的一个关键变量。遥感技术为大面积动态监测土壤水分提供了可能。简述了热惯量法、作物缺水指数法、植被指数距平法、微波遥感法、高光谱法五种目前为止比较成熟和广泛应用的土壤水分遥感监测方法和模型,并进行了优缺点分析。Soil moisture is a key variable of land surface parameterization. Remote sensing provides the possibility for dy- namic monitoring of soil moisture in a large area. Some relatively mature and extensively used methods and models for re- mote sensing monitoring of soil moisture are described here briefly, such as the thermal inertia method, the index method of crop water shortage, the departure method of vegetation index, the microwave remote-sensing method and the highly spectrographic method, and their advantages and disadvantages are also analyzed.
