摘要
以EOS-MODIS数据与土壤湿度地面观测数据为基础,采用植被供水指数法构建山东省春季土壤墒情监测模型,并以野外同步遥感监测场实测数据对模型精度进行验证,精度达84.54%。应用该模型对2008年4月上旬的地表土壤墒情进行了监测,结果与实际情况吻合。该模型的建立为山东省业务化土壤墒情遥感监测奠定了基础。
Based on EOS - MODIS data and ground observation data of soil moisture, the monitoring model for Spring soil moisture in Shandong Province was constructed by using VSWI （vegetation water supply index） method. The precision of the model was calculated by using data measured in field synchronizing RS station, which reached 84. 54%. Using the model to monitoring the surface soil moisture of Shandong Province in the first ten days of April, 2008, the results were in agreement with the actual situations. The model would establish the foundation for operational soil moisture remote sensing monitoring in Shandong Province.
