| 摘要: |
| 【目的】寻找合适的拟合模式。【方法】以天山西部山区的喀什河流域为研究区，基于1990―2000年的水文气象站点实测资料和同时间段的CFSR再分析数据，通过VIC模型模拟日和月时间尺度下水量平衡和能量平衡2种模式的径流过程，并分析了研究区内2种模式下空间分布差异较大的水文要素。【结果】在日和月时间尺度下，能量平衡模式的径流模拟效果在模型的率定期与验证期均优于水量平衡模式；依据实际气候和地理条件，因为缺乏对降雨和降雪的条件判断，并且未能够考虑到冰冻圈层对产汇流的影响，致使水量平衡模式不能够详细合理地解释水文要素的空间分布特点与差异性。【结论】总体而言，VIC模型能量平衡模式能够更好地模拟研究区径流过程及水文要素的空间分布特征。 |

| Abstract: |
| 【Objective】Find a suitable model for water balance in Kashi river basin. 【Method】Based on the data of hydro-meteorological station and Climate Forecast System Reanalysis (CFSR) during the period from 1990 to 2000, VIC model with water balance and energy balance was built under the daily scale and monthly scale. Process of runoff was simulated by different situations, and the differences of distribution of hydrological parameters under two modes were analyzed in the second section. 【Result】Results showed that the effect of runoff simulation under the energy mode was better than that under the water mode in daily and monthly scale. The judgments of rainfall and snowfall were neglected by water balance under the consideration of the real climate condition, and the impacts of cryosphere were ignored by water balance under the consideration of geography in this study area. Both of them were the main reasons why water balance cannot figure out the spatial characters and the spatial differences among the different hydrological parameter reasonably. 【Conclusion】In summary, the runoff and the distribution of hydrological parameters could be simulated better by VIC model with energy balance mode. |
