| 摘 要： | 以新疆2005年4-8月土壤墒情数据和MODIS卫星遥感数据为基础,通过对主要农作物生长季内NDVI变化、不同层次土壤相对湿度与地表亮温日较差的相关分析,构建了土壤相对湿度回归模型。所有模型均通过0.01水平的F检验。分析得出:新疆5月下旬以前利用热惯量法监测土壤墒情精度在81%以上,6月上旬-8月下旬单纯使用热惯量法监测土壤墒情精度不够理想。

| Abstract: | Based on simultaneous MODIS data and the soil relative humidity data from April to August in 2005 in Xinjiang,models of soil relative humidity was established.The models were also based on the NDVI of season change and the correlation analysis of soil moisture in different arrangement as well as the difference in temperature by day and night.All the models passed the F test of the significance level of 0.01.The results showed that the precision of soil moisture was above 81% by using the thermal inertia met... |
