摘　　要：矿产地发布辅助筛选系统是以地理信息系统(Geographic Information System,GIS)为基础,利用VB6.0开发而成。系统界面友好,反应速度快,可以直接读取现有的矿产地空间数据库、探矿权数据库、采矿权数据库中的数据进行空间分析,实现了重叠面积、重叠率自动计算,裁剪重叠区后矿产地新范围拐点标注与坐标的自动求取,重叠图自动生成,并用自定义窗体模版直接打印分析结果。Auxiliary filtration system design and application for issuance of mineral locations is developed with the help of VB6. 0 based on GIS technology. The system is provided with friendly interface and speedy response, the users may simultaneously and directly read and analyze the spatial database, database on prospecting rights, database on mining rights information, achieving and realizing an auto-calculation of the superposed areas and superposition rate, and an auto-sought of inflexion labels and coordinates for the new minerals scope after the cut-out of overlapped areas, self-formation of the overlapped charts, and printing with user-defined format.
