【摘要】 为解决我国西部地区气象水文站点稀少、分布不均匀的问题,并充分表达气象要素的空间差异性,利用VIC-3L模型对黑河上游山区流域进行了模拟研究,以检验该模型在干旱区较细网格尺度上的适用性和模型参数移植以及改造的可能性。模型所需要的土壤参数和植被参数主要通过野外实测、土壤普查数据或根据有关参考文献获得。模拟结果显示,在日、月尺度上的径流模拟变化趋势与实测径流除了在时间上有大约2～3d的滞后外,其他方面较为吻合,在丰水年日、月尺度上的径流模拟远好于同尺度上枯水年的模拟精度,说明模型在研究区具有一定的适用性,但有待于进一步改进。更多还原

【Abstract】 In order to solve the problems of scarcity and uneven distribution of meteorological and hydrological stations in west China and express the spatial difference of meteorological element,the mountainous river basin of upper Heihe River is simulated using VIC-3L model to check the applicability of the model with fine grid scale in arid region,and the parameter transportability and the possibility of modification of the model.The soil parameters and vegetation parameters required by the model are obtained through field measurement,general survey of soil and related reference papers.The simulation result show that except for 2 or 3 days’ delay,the simulated variation trend of runoff is consistent with the measured runoff in scale of day and month,and in this scale,the simulation precision in wet year is better than that in dry year.It’s verified that the model is applicable to some extent,however it still needs to be further modified.更多还原
