Abstract :
With the analysis of SWIR and NIR spectral space, and based on the Short Wave Perpendicular Water Stress Index (SPSI) of which was constructed by Abduwasit Ghulam. The SPSI was applied in the soil moisture retrieval during the growing period of wheat in April with full cover condition. The result showed there is a high correlation coefficient between SPSI and soil moisture in 0-30 cm, and has been tested that the SPSI has a potential in the soil moisture retrieval under full cover condition.
