基于MapObjects控件的中国矿情地理信息系统及应用--以铜矿地质分布为例

从研究地理信息系统开发模式和普及应用方面存在的问题入手，分析了开发地理信息系统的几种成功模式，在此基础上利用Map Objects控件和VB高级编程语言开发了中国矿情地理信息系统。该系统不仅实现了图像叠加、空间分析、地图打印等基本的GIS功能，而且还实现了矿产资源的评价分析功能。这些功能的实现旨在为研究中国的矿产资源提供必要的分析和评价手段，同时在中国铜矿的地质分布、成矿条件、成矿机理、时空分布等方面的实践研究中取得了良好的效果。

RESEARCH ON CHINA MINERAL GIS BASED ON MAPObBJECTS--A Case Study of Geological Distribution of Copper Mineral in China

There are some problems in the developing pattern and applying popularization of GIS, such as the inconsistency of data form, the imcompatibility of software flat. And, they have baffled the wide application of GIS seriously. Active X control technology is a powerful tool to resolve those problems. The China Mineral GIS (KQGIS) is an inquiry and analysis system which is developed by using MapObjects integrated with VB. Not only image overlay, spatial analysis, map printing ,but also evaluation and analysis of mineral resource are involved in this GIS system. All these functions are used well in the research of geological distribution of mineral deposits in China. This research involves geological distribution, formation conditions and mechanism of copper mineral deposits. The results show that the KQGIS based on active X control can perform all GIS function well. At last, the future application of GIS based on MapObjects is prospected.
