以地理信息系统（GIS）为数据处理平台，考虑黑河流域水循环的物理机制和流域水资源利用的人工系统，建立了分布式黑河流域水循环系统模拟模型（WEP-HeiHe），介绍了模型的结构，模拟包括两个方面：水文循环和能量循环。水文过程的组成部分包括蒸散、入渗、径流、地下水运动、地下水与河水的相互作用、地表径流，模型的参数采用英落峡水文站5年径流资料进行率定，并通过对1981年径流变化过程的模拟计算，验证了模型的有效性结果表明，该模型可用于环境变化条件下的流域水资源演变预测。
The GIS technique is applied as a data processing plateform to develop a distributed model for simulating the hydrological cycle system in the Heihe River basin,namely WEP-HeiHe.The physical mechanism of hydrological cycle and the artificial system of water utilization in the basin are considered.The structure of the model is introduced.The simulation consists of two aspects: hydrological cycle and energy cycle.The hydrological process components include evapotranspiration,infiltration,runoff,movement of ground water,interaction between groundwater and river water,overland flow,river flow and artificial cycle process of water utilization.The parameters of the model are calibrated by 5 years runoff data obtained from the Yingluoxia Hydrological station.The validity of the model is verified by the simulation calculation of runoff variation process in 1981 to 2002.It shows that the proposed model can be applied to forecast the evolution of river basin water resources under the conditions of changing environment.
