| Abstract: |
| 【Objective】Evaluate the accuracy of the calculation results of different models and the applicability of the models in different regions, and put forward the calculation model of potential evaporation suitable for different regions of Xinjiang.【Method】In order to solve the above problems, based on the measured meteorological data of 16different stations in Xinjiang from 1970 to 2015, the potential evapotranspiration was calculated by four kinds of potential evapotranspiration calculation models: comprehensive method, radiation method, mass transfer method and temperature method. In addition, TOPSIS method is used to rank the applicability of all the models in different regions from the accuracy and sensitivity.【Result】The results show that there is a high correlation between the radiation method and the measured value of evaporating dish in Xinjiang. The estimated potential evapotranspiration is much closer to the measured value than the comprehensive method, mass transfer method and temperature method. The Makkink model is the best and the Hamon model is the worst.;Net radiation and air temperature are the main influencing factors of evaporation in Xinjiang.【Conclusion】In southern Xinjiang, Makkink model and Penman-Monteith model are the best, followed by Priestley-Taylor (P-T), Hargreaves (Harg) and temperature method; in Northern Xinjiang, the radiation method is the most suitable, followed by penman model and penman Monteith model, and Hamon and MC Cloud model are the least suitable. |
