摘要
地理信息系统(GIS)是电子信息技术飞速发展的必然产物,与现代地球及其相关科学日益增长的需求相适应,以处理地球上任何具有空间方位的海量信息为特征,具定量、定时、定位等优点,近10年来已在地质矿产勘查中得到广泛应用。一个区域各种地质资料(图形、图像、文字、逻辑、数值)的GIS分析实际上代表该区域现阶段较为客观的总认识。目前,野外收集资料、数据建库、GIS分析等尚存在规范化、标准化等问题,GIS本身解决诸多专业性较强地质问题的能力亦不足。但GIS的进一步发展与完善必将使地质矿产勘查进入一个数字化的新时期。
<Abstrcat> Geographical Information System (GIS) is an inevitable product of the IT age, marked by processing of tremendous data and analyses in a quantitative, temporal and spatial way. Its occurrence is also largely related to the ongoing sophisticated demands of earth and relevant sciences. Thus, GIS analysis results for a region based on all available geological data in any forms like map, image, description, logic and numeric stand actually for the most objective recognition of this region. However, some standardization is now needed in the field data collection and database coding for GIS analysis purposes. In addition, GIS analysis functions are also limited in solving certain specific geological problems. But the further development of GIS must bring about a new digital age for geology and prospecting of mineral resources in the near future.
