摘要
土壤墒情预报是实施农田土壤水分有效调控的基础和前提。回顾总结了国内外土壤墒情预报研究发展的历史和现状,并对几种预报模型进行了重点对比分析。在此基础上,对现有研究中存在的问题及发展趋势和今后研究的重点进行了展望。
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.
