区域浅层地热能的多源信息系统构建

Construction of Multi-source Information System for Regional Shallow Geothermal Energy

浅层地热能分布广泛,资源储量巨大,但由于受岩性、埋深、气候和人类需求等多种因素的影响,因地制宜地对其进行开发利用异常复杂。根据浅层地热能点状调查数据,结合地热资源开发利用的需求,构建了区域浅层地热能的多源信息系统。该多源信息系统采用面向对象程序设计方法,以用户较多的Windows主流操作系统作为系统运行平台,数据库选择性能优越、稳定可靠的Microsoft SQL Server 2008作为后端数据库,GIS平台采用地矿行业使用的MapGIS平台,前端数据录入系统采用快速开发工具Delphi作为主流开发工具,数据管理和分析应用系统则采用Visual C++6.0开发,并应用Delphi组件技术和ActiveX控件技术实现软件系统的开发,最终可实现对浅层地热能调查数据的点状采集和管理,区域上自动生成所需的各种成果图件,对研究区地热能资源适宜性进行评价分区。该多源信息系统的构建能够为区域浅层地热能调查的多源数据搭建面向对象的综合管理平台,并能快速、有效地完成浅层地热能资源适宜性评价分区。

Shallow geothermal energy is widely distributed and has huge reserves.However,the efficient development and utilization of shallow geothermal energy is extremely complex due to lithology,burial depth,climate and human needs.According to the point source survey data of shallow geothermal energy and the demands of development and utilization of geothermal resources,this paper applies the object-oriented programming method to constructing a multi-source information system for regional shallow geothermal energy.The multi-source information system takes the Windows mainstream operating system with more users as the system operation platform,and uses Microsoft SQL Server 2008 as the back-end database,GIS platform adopts MapGIS platform used by geological and mineral industry,the front-end data entry system uses Delphi as the mainstream development tool,and the analysis application system uses Visual C++6.0 as the development tool.The software system is developed by using Delphi component technology and ActiveX control technology,which realizes the point collection and management of shallow geothermal survey data.All kinds of results maps can be generated automatically in the domain,and the suitability evaluation of the research area can be carried out.The framework of the information system can build an object-oriented integrated management platform for multi-source data of regional shallow geothermal energy survey,and can quickly and effectively complete the shallow geothermal suitability evaluation&zoning.
