水资源管理业务系统划分是水资源管理信息系统规划的主要内容之一。基于BSP（Business System Planning）方法，通过对水资源管理目标和业务过程的识别和梳理，建立了水资源管理业务模型，用来定义数据类，构建C-U矩阵。最后，通过对C-U矩阵中数据关系的分析，对水资源管理业务子系统进行了划分。据此划分的水资源管理业务系统以数据和数据关系为核心，独立于业务组织结构，对业务环境变更具有较强的适应性,可以用稳定的数据结构支撑较长时间的水资源管理信息系统建设。

Water resource management business system division is one of the main contents of water resources management information system planning. Based on the BSP（Business System Planning）method and the identification and ordination of water resources management and business processes, a water management business model was developed, which was used to define the data class and to construct the C-U matrix; Through the analysis of data relationships in the C-U matrix, the business subsystems were divided for the water resources management business system. The core of the obtained water management business system division was data and data relationships. Furthermore, the system was independent of the organizational structure, thus it had strong adaptability to the environmental change. The stable data structure can be used to support a long-time development of water resources management information system.
