摘要
土壤水分是水文学、气象学、土壤学、生态学以及农业科学等研究领域中的一个重要的参数。总结了当前国内外基于遥感信息监测土壤水分的原理和方法,特别是对数据同化法进行了着重阐述。通过对各类方法的比较,认为数据同化法是监测土壤水分最有前景的方法之一。
Soil moisture is an important factor in research fields of hydrology, meteorology, pedology, ecology, agricultural science and so on. But it is a difficult one to gain. The principle and methods of monitoring the soil moisture based on remote sensing information are reviewed, Especially much attention was paid on the data assimilation method. By comparing these methods,the data assimilation method will have a promising prospect for monitoring the soil moisture.
