摘要: 利用卫星监测的土壤含水量资料,研究了土壤水分与各气象要素之间的关系以及土壤水分自身的变化规律;并根据这些规律建立由多种预测模式组成的土壤水分动态监测与预测系统。该系统的预测准确率在90%以上。

关键词: 土壤水分, 监测, 预报模式

Abstract: By using soil moisture data from the polar orbiting satellite monitor,the relationship between soil moisture and meteorological elements and the variation law of soil moisture was studied in this paper. The soil moisture monitor and predictive system consisting of multi model were established on the basis of these laws. The predictive accuracy of the system was over 90%.
