摘要

通过对SWIR和NIR光谱空间的分析，并基于Abduwasit Ghulam构建的短波垂直水分胁迫指数(SPSI)。将SPSI应用于4月全覆盖条件下小麦生育期土壤水分反演。结果表明，SPSI与0 ~ 30 cm土壤湿度具有较高的相关系数，表明SPSI在全覆盖条件下的土壤湿度反演中具有一定的潜力。

The application of shortwave infrared Perpendicular Water Stress Index in drought monitoring under normal vegetation coverage

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.
