| 摘要: |
| 【目的】评价不同模型计算结果的准确性以及模型在不同地区的适用性，提出适合于新疆不同区域的潜在蒸发量计算模型。【方法】针对上述问题，本研究基于新疆16个不同站点1970-2015年的实测气象资料，以实测蒸发为基准，采用综合法、辐射法、质量传输法、温度法四类潜在蒸散发计算模型计算潜在蒸散发。通过随机森林模型分析了实测蒸发数据的主要影响因素，并利用多属性决策方法TOPSIS法从模型计算精度与敏感性对不同地区所有的计算模型进行适用性排序。【结果】结果表明，在全疆范围内，辐射法与实测值相关性高，估算的多年潜在蒸散发量明显比综合法、质量传输法和温度法更接近实测值，其中Makkink模型估算效果最好，Hamon模型最差；净辐射量和气温为新疆地区蒸发量的主要影响因素。【结论】在南疆地区，辐射法中的Makkink模型与综合法Penman-Monteith模型适用性最好，Priestley-Taylor(P-T)、Hargreaves(Harg)等辐射法次之，温度法最不适用；在北疆地区，辐射法适用性最佳，Penman模型和Penman-Monteith模型次之，Hamon和Mc Cloud模型最不适用。 |

| 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. |
