基于分数阶植被归一化系数的表层土壤湿度分析模型

Analysis Model for Surface Soil Moisture Based on FONDVI

土壤湿度是水文学、气象学以及农业科学研究领域的一个重要参数。主要验证了在可见光与近红外波段预测土壤湿度的可能性。在经典的植被归一化系数公式的基础上,提出了新的分数阶植被归一化系数公式,通过试验验证可以提高土壤湿度与归一化系数的相关系数值,为将来使用无人控制机精确地预测局部范围内的土壤湿度提供了理论基础。

Soil moisture is an important parameter in the research fields of hydrology,meteorology and agriculture sciences.The possibility of visible light and near infrared waveband in the prediction of soil moisture was mainly validated.Based on the classical normalize difference vegetation（NDVI） formula,a new FONDVI formula was proposed.Through test validation,the correlation coefficient between soil moisture and NDVI could be increased.The research provided theoretical basis for using unmanned control machine to predict the soil moisture in the local range accurately in future.
