摘要
土壤含水量是土壤的一项重要指标,如何通过遥感反演获取高精度的土壤含水量一直是研究者关注的问题。本文针对利用微波反演裸露地表土壤含水量和植被覆盖地表土壤含水量的问题,比较了相关研究在反演模型、反演技术流程方面的改进和不足,分析了反演问题的关键环节,结合微波和光学联合反演地表土壤含水量的研究进展,指出了微波遥感反演土壤水分研究的发展趋势。
Soil moisture is the important indicator of soil that how to gain high precision soil moisture is the attention issue of researchers. For the problems of bare surface and vegetated surface soil moisture retrieval by microwave remote sensing, the paper compared improvements and deficiencies of correlative researches on retrieval models and technologies, analyzed the key steps of retrieval issue. Combining the present research on land surface soil moisture inversion by the integration of microwave and optic, it pointed out the developing trends of soil moisture inversion by microwave remote sensing.
