BTOPMC is a distributed hydrological model with strong physical basis, which is mainly used for teaching and drainage research. The model needs to be software, so that it can be used for drainage and water resources management. In this paper, the computer system of the model is designed, and the BTOPMC is improved. The system is composed of a data layer, a model layer, a communication layer, a data expression layer and a user layer. The client/sever mode is used for the operation environment, and both manual rating mode and automatic rating mode are provided. The SCE-UA global optimal algorithm with built-in 7 objective functions is used for the automatic rating. Multi core parallel computation is implemented by using OpenMP multi core concurrent programming technology in the runoff producing module. The system provides afi ne method and a simple tool for both operation and water resources management in the river basin.%BTOPMC是一个具有较强物理基础的分布式流域水文模型，主要用于教学和流域研究，模型有待软件化，以便用于流域作业预报和水资源管理。采用多层架构体系设计了该模型的计算机系统，对BTOPMC进行改进，系统由数据层、模型层、通信层、数据表达层和用户操作层组成，运行环境采用客户端/服务端模式。提供手动和自动2种参数率定模式，自动率定采用SCE-UA全局最优算法，内置7种目标函数。采用OpenMP多核并发编程技术在产汇流模块实现了多核并行计算。
