土壤墒情诊断理论和方法
Theory and method of soil moisture diagnosis
摘要
Abstract
This paper reviewed the theory and methods of soil moisture diagnosis,and introduced the status quo of soil moisture monitoring,diagnosis and prediction in China.Six independent models were emphatically presented,which included balance diagnostic model,statistical diagnostic model,subtractive statistical diagnostic model,ratio statistical diagnostic model,interval days statistical diagnostic model and movable statistical diagnostic model.Meanwhile,an integrated diagnosis model by combined application of the six independent models was also introduced.Models were established by the data of 87 monitoring sites in 23 counties in 7 provinces during the period of 2012-2014,and were validated by the data of 2015.The results showed that all the models were simple and the parameters were easy to obtain.Integra()ed diagnostic model was superior to the 6 independent models.In conclusion,the 6 independent models and the integrated diagnostic model were suitable for the diagnosis and prediction of soil moisture based on precipitation.关键词
