　　摘 要：正确认识水沙作用下河床调整的方向、速率和过程，是治淮首先需要解决的重大科技问题。为提高断面资料的管理应用水平，减少河床演变分析中的耗时浪费，采用面向对象的可视化语言和工具，构建河床演变辅助分析系统。该系统以淮河中游区为研究对象，收集多种来源、不同类型的海量断面资料，通过整理和标准化，建立高质量的河道断面数据库。在此基础上，运用河流动力学理论，设计和开发一整套描述河床演变特征的数据挖掘工具，能快速、高效地对水文站固定断面及指定河段的滩槽变化、冲淤时空分布进行计算和分析。该系统的研制有效提升河床演变分析的效率，促进科学数据的共享。简要介绍其总体框架和分析功能，以便为从事淮河规划、设计的相关学者了解和使用。

　　Abstract: It is an important scientific and technological problem to be solved firstly to correctly understand the direction, velocity rate and process of river bed adjustment under the action of water and sediment. In order to improve the management and application level of section data and reduce time waste in riverbed evolution analysis, auxiliary-analysis system of riverbed evolution is constructed by using object-oriented visual language and tools. The system, taking the middle reaches of the Huaihe River as the research object, collects massive cross-section data of various sources and different types. A high-quality river section database is established through sorting and standardization. On this basis, a set of data mining tools is designed and developed to describe the riverbed evolution characteristics by using river dynamics theory. These tools can quickly and efficiently calculate and analyze variation of beach and trough, spatiotemporal distribution of scouring and silting of hydrologic station fixed cross-section and designated reach.The system can improve the riverbed evolution analysis efficiency and promote scientific data sharing. The system’s general framework and analysis function are introduced, which is beneficial to Huaihe River planning and design related scholars’ research.
