　　摘 要：正確認識水沙作用下河床調整的方向、速率和過程，是治淮首先需要解決的重大科技問題。為提高斷面資料的管理應用水平，減少河床演變分析中的耗時浪費，采用面向對象的可視化語言和工具，構建河床演變輔助分析系統。該系統以淮河中游區為研究對象，收集多種來源、不同類型的海量斷面資料，通過整理和標準化，建立高質量的河道斷面數據庫。在此基礎上，運用河流動力學理論，設計和開發一整套描述河床演變特征的數據挖掘工具，能快速、高效地對水文站固定斷面及指定河段的灘槽變化、沖淤時空分布進行計算和分析。該系統的研制有效提升河床演變分析的效率，促進科學數據的共享。簡要介紹其總體框架和分析功能，以便為從事淮河規劃、設計的相關學者了解和使用。

　　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.
