摘　　要：针对江苏沿海滩涂围垦开发的难点,在海洋时空数据模型的基础上探讨了辐射沙脊群时空信息集成的方法,初步尝试了准同步思想在时空数据管理中的应用。系统在.NET开发平台下,结合Arc GIS二次开发、数据库编程,设计开发了C/S和B/S混合结构的辐射沙脊群时空信息集成系统。水文站管理、漂流浮标示踪、遥感影像检索3大关键模块与数据源、数据整编、数据库管理、模型库和业务表达5层互成经纬结构,实现数据交互查询和管理。系统主要功能包括数据整编、模型计算、数据分析、时空数据接收、成果展示和分享,为辐射沙脊群区域围垦开发及水文监测提供数据支撑和技术支持。In view of the difficulties of exclamation and exploitation in the coastal area of Jiangsu Province,we dis-cussed the method of spatio-temporal information integration for radial sand ridges based on marine spatio-temporal data model,and preliminarily applied quasi-synchronization to the spatial and temporal data management.A system involving ArcGIS secondary development and database programming is designed and developed as C /S and B /S structure on the development platform of MicroSoft.Net.The system consists of hydrological station management, drifting buoy tracer,retrieval of remote sensing information as key modules,and data source,data reorganization, database management,model base and business expression as layers,which together make up a fabric structure of interactive data query and management.The main function of this system includes data reorganization,model calcu-lation,data analysis,spatio-temporal data receiving,result displaying and sharing.It provides data support and technical support for the reclamation exploitation and hydrological monitoring in radial sand ridge field.
