摘要
《省级区域化探数据库信息系统ＰＧＤ２．０》是以中文Ｗｉｎｄｏｗｓ９５为平台，研制的一套集数据管理、处理、解释和制图为一体的区域化探综合应用系统，目前已推广应用。该系统建立了四个数据库：区域化探数据库、监控数据库、中大比例尺数据库及地质和地理图形库。同时提供了可视化多模式条件检索功能。系统提供的数据处理方法能对区域化探数据做多元统计分析、数据校验、各种投影变换及系统调平等处理；系统提供的制图功能，可以绘制等值线图、充填颜色的彩色等值线图、数据点位图、数据符号图和色块图。系统还提供了异常解释功能，能以衬度异常的面金属量ＮＡＰ值自动圈定异常。在辽宁省已经使用该软件建立了区域化探数据库，这给区域化探资料的使用带来了很大的方便。在异常筛选、找矿及战略选区等方面，也起到了不可替代的作用。
The Provincial Geochemical Database and Information System PGD2.0 is a set of comprehensive applied system on the base of Chinease Windows 95 platform, by which data can be managed, processed and mapped . At present, the system has been spread and used. In the system, there are 4 databases: geochemical exploration database, sample analysis quality controlling database, medium large scale geochemical exploration database, and geological and geographical graphic database. It has a retrieving function of visual multi pattern conditions;a data processing function,by which the geochemical exploration data can be multivariable statistics analyzed and verified, projection transformed and system balanced; a mapping function, by which a contour diagram, or a colored contour diagram, or data position map, or a data symbol map and color block map all can be mapped; and a function of anomaly explanation. In Liaoning province, with the use of software the geochemical exploration database has been set up. After the establishment of the database, it is more convenient to use geochemical exploration data, and it is useful for anomaly sieving, exploration, and looking for target area of mineral deposits.
