【摘要】：随着地勘项目的广泛开展以及各种物化探新设备的投入使用，依靠人工监管、纸质记录的地勘项目监管模式开始逐渐被替换。取而代之的是融合了网络技术、地理信息系统、数据挖掘等技术的信息化地勘项目监管平台。中央地勘基金远程调度监管平台就是在总结以往地勘项目监管经验以及国土资源信息化建设的基础上提出的新一代地勘项目监管平台。地勘项目产生的地质勘查信息、监管信息，信息量巨大且具有明显的空间特征，同时，地勘项目监管本身也需要用到涉及全国范围内的海量的基础地理信息，如地形图、地质图、遥感影像等。因此地勘基金监管平台必须选择有效的空间数据组织方法，建设合理高效的空间数据库，，实现地勘项目相关空间数据的采集、存储、处理、可视化，最终为地勘项目监管人员提供决策依据。化探工程项目是地勘项目中最常用的找矿方法之一，也是各地勘项目管理系统的重点监管内容。本课题就是针对化探工程项目的数据采集、空间数据存储管理和可视化进行的实现，并且探讨了DEA在化探工程项目监管中的应用。地勘项目管理系统的投入使用极大的提高了化探工程项目的监管效率、监管力度和监管水平，海量的化探数据、空间数据被存储在关系数据库中，通过监管手段可以方便的查看相应的监管信息，并且能够应用数据挖掘对其进行监管分析。本课题以化探工程项目监管做为研究内容，以GIS实现模块做为研究重点，以数据包络分析的监管应用为研究创新，主要研究内容有如下几个方面： 1)研究数据包络分析理论的基本原理，探讨DEA的主要实现模型，并重点实现数据包络分析在化探工程项目中的实际应用。 2)深入研究空间数据库相关理论，包括空间数据库的四种类型及其优缺点，主流的空间数据模型等。 3)探讨系统的重要构成——MapGIS平台的相关组件的工作原理和在项目中的应用，主要包括MapGIS-SDE和MapGIS IGServer。 4)化探工程项目监管模块具体实现，DEA应用、空间数据存储、可视化等。
[Abstract]:With the extensive development of geological prospecting projects and the use of various new geophysical and geochemical exploration equipment, the supervision mode of geological prospecting projects based on paper records has been gradually replaced by manual supervision. Instead, the geological prospecting projects have been replaced by a combination of network technology and geographic information systems. The remote dispatching and supervising platform of Central Geological Prospecting Fund is a new generation based on summarizing the experience of geological prospecting project supervision and the construction of land and resources informatization. Geological prospecting project supervision platform. The geological exploration information, supervision information and information produced by geological prospecting projects are huge and have obvious spatial characteristics. At the same time, the supervision of geological prospecting projects themselves also needs to use vast amounts of basic geographic information, such as topographic maps, which are related to the whole country. Geological map, remote sensing image and so on. Therefore, the geological prospecting fund supervision platform must select effective spatial data organization method, construct reasonable and efficient spatial database, and realize the acquisition, storage, processing and visualization of spatial data related to geological prospecting project. Finally, it provides the decision basis for the supervisor of geological prospecting project. Geochemical exploration project is one of the most commonly used prospecting methods in geological prospecting projects, and it is also the key supervision content of each geological prospecting project management system. The realization of spatial data storage management and visualization is discussed, and the application of DEA in the supervision of geochemical exploration project is discussed. The application of geological prospecting project management system greatly improves the supervision efficiency of geochemical exploration project. Supervision and supervision level, massive geochemical data, spatial data are stored in the relational database, through regulatory means can easily view the corresponding regulatory information, and can use data mining to monitor its analysis. This topic takes the geochemical engineering project supervision as the research content, takes the GIS realization module as the research emphasis, takes the data envelopment analysis supervision application as the research innovation, the main research content has the following several aspects:. The main contents are as follows: 1) the basic principle of data envelopment analysis is studied, the main realization model of DEA is discussed, and the practical application of data envelope analysis in geochemical exploration project is emphasized. 2) deeply study the related theories of spatial database, including four types of spatial database, their advantages and disadvantages, the mainstream spatial data model and so on. 3) discussing the important component of MapGIS platform and its application in the project, including MapGIS-SDE and MapGIS IGServer. 4) the application of DEA, spatial data storage, visualization and so on.
