To better simulate the river basin hydrological cycle and to solve practical engineering application issues, this paper describes the distributed-framework basin modeling system (DFBMS), which concatenate a professional hydrological model system, a geographical integrated system, and a database management system. DFBMS has two cores, which are the distributed-frame professional modeling system (DF-PMS) and the double-object sharing structure (DOSS). An area/region that has the same mechanism of runoff generation and/or movement is defined as one type of hydrological feature unit (HFU). DF-PMS adopts different kinds of HFUs to simulate the whole watershed hydrological cycle. The HFUs concept is the most important component of DF-PMS, enabling the model to simulate the hydrological process with empirical equations or physical-based submodules. Based on the underlying source code, the sharing uniform data structure, named DOSS, is proposed to accomplish the integration of a hydrological model and geographical information system (GIS), which is a new way of exploring temporal GIS. DFBMS has different numerical schemes including conceptual and distributed models. The feasibility and practicability of DFBMS are proven through its application in different study areas.

分布式框架盆地建模系统：I.概述和模型耦合

为了更好地模拟流域水文循环并解决实际工程应用问题，本文介绍了分布式框架流域建模系统（DFBMS），该系统将专业水文模型系统，地理集成系统和数据库管理系统连接在一起。DFBMS具有两个核心，分别是分布式框架专业建模系统（DF-PMS）和双对象共享结构（DOSS）。具有相同的径流产生和/或运动机理的区域/地区被定义为一种水文特征单元（HFU）。DF-PMS采用不同种类的HFU来模拟整个流域的水文循环。HFU的概念是DF-PMS的最重要组成部分，它使模型能够使用经验方程或基于物理的子模块来模拟水文过程。在基础源代码的基础上，提出了共享的统一数据结构DOSS，以实现水文模型与地理信息系统（GIS）的集成，这是探索时态GIS的一种新方法。DFBMS具有不同的数值方案，包括概念模型和分布式模型。DFBMS在不同研究领域的应用证明了其可行性和实用性。
