摘要: 针对东江流域,在基于 HSPF 水文模型的基础上,构建了东江流域分布式水文模型。详细介绍了 HSPF 分布式水文模型构建的原理、模型数据准备、模型构建以及模型验证过程。从气象分布变异的角度出发,将东江流域划分成 51 个子流域,从物理分布变异的角度出发,将东江流域的土地利用类型与土壤类型和坡向重新叠置成 29 种特征类型的下垫面。通过模型的模拟效果来看,两校准站(河源站和博罗站)的相对误差均小于 15% ,NASH 系数都在 0.9 以上,模拟效果良好。

Abstract: A distributed hydrological model is established for Dongjiang watershed based on Hydrological Simulation Program-Fortran (HSPF) Model. The theory of the construction, the data preparation, the model construction and model calibration are presented in details. The watershed is divided into 51 subfields from the perspective of spatial heterogeneity; while in terms of physical heterogeneity, the land use type, soil type and slope aspect are overlaid into 29 types of underlying surfaces. The relative errors at two calibrated stations (Heyuan station and Boluo station) are less than 15% and the NASH coefficients are larger than 0.9, which indicates a favorable simulation effect.
