| Abstract: | The characteristics of Tianjin agricultural production were firstly analyzed in this study, and then the algorithm for the two methods was introduced, i.e. precipitation and integral humidity indices and their evaluation result based on agricultural water demand and water law. The results showed that evaluation assessment results were in good agreement with the fact, indicating agricultural significance of these two drought indices. |
