摘要: 通过对当前矿产资源规划信息化建设现状,以及GeoData Service技术特征和优势的基础上,提出面向服务理念架构3层B/S模式的矿产资源规划信息服务系统。着重对系统的逻辑结构、空间数据库、系统功能进行了详细设计,并对封装了矿产资源规划成果数据的GeoData Service服务的构建要点、处理方法及该种处理方法的技术优势进行了阐述;同时给出了在Dotnet框架下,采用ArcGIS Server.NET ADF开发技术,开发实现的矿产资源规划信息服务系统的运行实例。最后,剖析了Web ADF异步回调技术、基于JavaScript的Web动态导航技术、ADO.NET数据访问技术、系统性能的整体优化方法等关键技术在系统中的具体实现。系统运行表明,矿产资源规划信息服务系统为矿产资源规划信息化建设领域系统建设的架构方式从Web GISystem到Web GIServices的转变及矿产资源规划成果数据信息的同步更新与管理、远程提取、网络分布式共享拓展了一种新的应用模式。

Abstract: Up to now, China has implemented two rounds of national mineral resources planning and accumulated a large number of mineral resources planning data. However, current situation of informatization construction of mineral resources planning is backward relatively. There are still some problems, especially how to research and implement a set of efficient information service system which conforms to the development requirements of mineral resource planning information construction, and making all kinds of users acquire information or services of mineral resources planning by a network on-demand is a problem that deserves thorough research. Through the study on current situation of informatization construction of mineral resources planning, and on the basis of analysis of the GeoData Service's technical features and advantages, this paper proposes to build the Mineral Resources Planning Information Service System (MRPISS) which adopts three-tier B/S model with the service-oriented concept in order to solve those problems above. Firstly, the paper focuses on the detailed design of the system's logical structure, spatial database and functions. Secondly, it describes the key points in the system building, the processing method and the method's technical advantages of the GeoData Service, which the results of the mineral resource planning data is packaged into. Besides, the practical running effect of the system which is developed with the technology of ArcGIS Server.NET ADF under the Dotnet framework is demonstrated. Finally, the paper analyzes how to implement some key technologies in the system, such as the asynchronous callback technology of Web ADF, the dynamic navigation of Web based on JavaScript, the data access technologies of ADO.NET, the optimization of the system performance and so on. The running results of the Mineral Resources Planning Information Service System built in this paper shows that it brings a change which from Web GISystem to Web GIServices on the approach of the system architecture in the fields of informatization construction of mineral resources planning, and provides a new application model for synchronous update, remote extraction, sharing and management of the mineral resources planning data under a distributed network.
