摘  要:
The forecast of soil moisture is the most effective way for understanding the dynamic changes of soil water and regulating the status of soil water.This paper summarizes the research advances of soil moisture forecast at home and abroad,and analyzes the basic theories of different forest models.Moreover,it discusses the existing problems in the current studies on the forecast models of soil moisture,and prospects the development trends and the main research aspects in the future.
