研究农田水分动态和预测未来的变化,是管好农田水利工程、制订用水计划的重要依据,对于制订抗旱防旱、防治渍害和土壤盐碱化措施也是十分重要的. 农田水分状况的预报,是在当前农田水分状况的基础上,结合短中期气象预报,确定未来某一时刻农田中土壤含水量的多少及其在剖面上的分布.以前大都采用相关分析
Studying the dynamic changes of farmland moisture and predicting future changes is an important basis for managing farmland water conservancy projects and formulating water plans and is also very important for formulating measures to combat drought and drought, prevent soil pollution and soil salinization.Water farmland water status prediction, Is based on the current state of farmland moisture, combined with short-term meteorological forecast to determine the future of a certain amount of time in the farmland soil moisture content and its distribution in the profile. Most of the previous use of correlation analysis
