摘要:
栅格新安江模型是在概念性新安江模型的理论基础上,以栅格为计算单元,结合地形地貌和下垫面特性构建出来的水文模型.在于桥水库流域上游的水平口流域应用栅格新安江模型,研究该地区洪水要素的空间变化以及洪水形成过程,讨论洪水模拟效果来验证模型在半湿润地区的适用性.选取水平口流域1978-2012年的洪水进行模型计算,模拟结果较好地反映了流域产流面积的时空变化,且均达到乙级以上精度.初步表明栅格新安江模型在半湿润地区有较好的适用性.

Abstract:
Grid-Xinanjiang hydrology model used in this study is a spatial grid-data processing model which combines theory of the conceptual Xinanjiang model with different kinds of analysis on DEM, soil type and land cover data. We applied the model in Shuipingkou Reservoir located in the upstream of Yuqiao Basin to study the spatial variation of flood factors and the flood procedure in a semi-humid region. The simulation experiment based on the data ranged from 1978 to 2012, and we analyzed the flood simulations to check the applicability of this model in semi-humid regions. The simulation results turned out to be satisfied that showed significant changes of runoff producing in various areas of the basin, suggesting that the model has the potential in space to be adaptable for the semi-humid regions.
Key words:  Grid-Xinanjiang model  change of areal runoff producing  flood simulation  Yuqiao Reservoir  Shuipingkou Basin
