土壤的各种理化性状，地形的分异作用以及气候变化和人为的土壤管理措施对土壤水分状况有不同的影响，地表特征与土壤水分状况也存在着一定的相关性。世界上遥感研究比较先进的国家一般从７０年代初就全面系统地进行了土壤水分的研究，我国系统地进行土壤水分研究是近几年的事。土壤水分遥感监测要经过复杂的中间过程，波段及变量选择，传感器性能等因素对土壤水分监测是至关重要的；研究方法及途径的选择都要根据土壤类型、传感器性能以及工作目的等因素合理确定，该领域的研究有待进一步完善。
Soil physical and chemical properties, terrain differentiation and climate change and man-made soil management measures have different impacts on soil water status. There is also some correlation between surface characteristics and soil water status. Countries with more advanced remote sensing research in the world generally carried out a systematic and systematic study of soil moisture from the early 1970s. The systematic study of soil moisture in China is a recent issue. Soil moisture remote sensing monitoring through complex intermediate processes, band and variable selection, sensor performance and other factors is crucial for soil moisture monitoring; research methods and ways of choice must be based on soil type, sensor performance and the purpose of the work and other factors reasonable Confirmed, the research in this field needs to be further improved.
