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 wheat growing period in April with full cover condition. The result showed there is a high correlation coefficient between SPSI and soil moisture in depth of 0-30 cm, and has been tested that the SPSI is an effectiveness index in the soil moisture retrieval under full cover condition.
