Abstract: Based on the results of researches in the feature column of this issue, this paper makes theoretical analysis, comprehensive evaluation and prospect of the moisture diagnosis models, aiming to establish more practical moisture diagnosis models. The results are as follows: (1) The precipitation data of 87 moisture monitoring sites could be replaced by the precipitation of their nearest meteorological stations; (2) The diagnostic qualified rates of the 6 independent models and the comprehensive model (two categories: the time interval diagnosis and the daily diagnosis) established by 87 moisture monitoring sites were all above 75%; (3) The integrated model was better than the independent models used alone; (4) All models and parameters were established and determined according to the monitoring sites, without the influence of the underlying surface factors; (5) All models were simple, with three independent variables (initial soil moisture content, precipitation during period of monitoring, and the days between two monitoring dates), and parameters easy to get. The models can be established as long as there is a series of soil moisture monitoring data and corresponding precipitation data (monitoring sites or nearby weather stations).
