【摘要】：野外数据采集是地下水资源调查的重要组成部分,在信息技术推动下,野外数据采集从手工采集方式逐步向信息化模式过渡,避免了传统手工方式从野外数据记录,数据整理筛选,再输入到数据库进行统一管理所引起的低效率、易录错等缺点。 DGSGIS平台(数字地质调查GIS基础平台)是由中国地质调查局发展研究中心自主开发的数字地质调查系统软件平台,针对数字地质调查应用的需求,做了针对性的设计,产品较齐全,功能较稳定,适用于地质调查中不同的应用规模,实现了地质调查的数字化流程,并取得了明显的区域地质调查效益和社会效益。基于DGSGIS平台开发地下水资源调查野外数据采集桌面系统,一方面是测试DGSGIS平台能否满足系统开发的功能需求并提出需求建议；另一方面是在统一底层平台上做到专业化、公益化,为地下水资源调查野外数据采集系统的推广使用提供便捷。基于DGSGIS平台的地下水资源调查野外数据桌面系统依据《全国地下水资源及其环境问题调查评价技术要求》和《区域地下水资源调查评价数据库标准》设计开发,主要用于地下水资源野外调查数据整理、野外调查数据准备、实际材料图绘制等。系统实现了对地下水资源调查野外数据的数据管理、图层数据浏览、图层数据查询、属性数据输出和专题制图等功能。论文的主要内容包括： 1.介绍国内外野外地质数据信息化的研究现状,重点分析在地下水调查领域取得的研究成果。 2.根据实际水文地质调查过程和桌面系统的应用功能,对系统进行全面需求分析,在此基础上确定系统总体设计方案,完成系统数据分析、界面设计、数据库设计、功能设计、环境设计等。开发过程中利用现有的软件开发成果,结合DGSGIS平台功能开发接口情况及现阶段工作进展情况进行系统功能详细设计,确定具体开发功能。 3.系统开发涉及的研究内容、工作流程及体系结构。 4.结合DGSGIS平台二次开发接口的完善情况,确定具体开发功能为图形数据显示、图形数据检索、根据属性表生成点、图层属性导出Excel,并在开发过程中测试DGSGIS二次开发接口。 5.以华北平原地理底图及地下水资源野外调查数据为例对系统功能进行验证,包括对DGSGIS平台的应用效果进行总结,并提出改进建议。 6.对研究成果和存在问题进行总结,为后续工作提供依据。
[Abstract]:Field data acquisition is an important part of groundwater resources investigation. With the promotion of information technology, field data collection is gradually transferred from manual collection to information mode, thus avoiding the traditional manual data recording from the field. Data sorting and filtering, then input to the database for unified management caused by the inefficiency, easy to record errors and other shortcomings. DGSGIS (Digital Geological Survey GIS Foundation platform) is a software platform of Digital Geological Survey system developed by China Geological Survey Development Research Center. The product is complete, the function is relatively stable, is suitable for the geological survey in the different application scale, has realized the geological survey digitization flow, The development of field data acquisition desktop system of groundwater resources survey based on DGSGIS platform is to test whether the DGSGIS platform can meet the functional needs of the system development and put forward demand suggestions; On the other hand, specialization and commonweal are achieved on the unified bottom platform, which provides convenience for the popularization and use of field data collection system for groundwater resources survey. The field data desktop system of groundwater resources survey based on DGSGIS platform is designed and developed according to the Technical requirements of investigation and Evaluation of groundwater Resources and its Environmental problems in China and the Standard of Regional groundwater Resources Survey and Evaluation Database. It is mainly used in the field survey data collation of groundwater resources, the preparation of field survey data, the drawing of actual material map, etc. The system realizes the data management of groundwater resources survey field data, the browsing of map layer data, the querying of layer data, etc. Functions such as attribute data output and thematic mapping. The main contents of this paper are as follows:. 1. Introduce the research status of field geological data information at home and abroad, and analyze the research results in the field of groundwater survey. 2.According to the actual hydrogeological survey process and the application function of the desktop system, the overall requirement analysis of the system is carried out, and on this basis, the overall design scheme of the system is determined, and the system data analysis, interface design, database design, function design are completed. Environment design and so on. In the process of development, the system function is designed in detail by using the existing software development results, combining with the DGSGIS platform function development interface and the current work progress, and the specific development function is determined. 3. Research contents, workflow and architecture of system development. 4. Combined with the perfection of the secondary development interface of DGSGIS platform, it is determined that the specific development functions are graphic data display, graph data retrieval, export of Excel according to attribute table generation point and layer attribute, and test DGSGIS secondary development interface in the course of development. 5. Taking the geographical base map of North China Plain and field survey data of groundwater resources as examples, the system functions are verified, including the application effect of DGSGIS platform summarized, and suggestions for improvement are put forward. 6. Summarize the research results and existing problems, and provide the basis for the follow-up work.
