本文从空间分析和可视化的角度简要回顾了地理信息学在勘查地球化学中的应用，论证了地理信息学在探索地球化学模式和识别地球化学异常方面的优势。重点讨论了地理信息学在地球化学填图、地球化学异常识别和地球化学模式模拟中的应用。地球信息学的优势包括：（1）地球化学数据在地质图上的叠加，有助于地球化学工作者理解空间地球化学模式和可视化地球化学异常;（2）局部邻域空间分析，考虑地球化学模式的局部空间结构，是识别地球化学弱异常的有力工具;（3）基于地质约束的地球化学模式模拟，有助于认识地质作用。今后的研究重点应是开发和应用地理信息系统中的各种化探数据处理功能，以促进地球信息学在地球化学勘查和环境研究中的发展。
This paper briefly reviews the application of geoinformatics in exploration geochemistry from the perspective of spatial analysis and visualization, and demonstrates the advantages of geoinformatics in exploring geochemical patterns and identifying geochemical anomalies. In particular, the application of geoinformatics to geochemical mapping, recognition of geochemical anomalies and simulation of geochemical patterns are discussed. The benefits of geoinformatics include: (1) overlay of geochemical data on a geological map, which helps geochemists to understand spatial geochemical patterns and visualize geochemical anomalies; (2) local neighbourhood spatial analysis, which considers the local spatial structure of geochemical patterns, as a powerful tool to identify weak geochemical anomalies; and (3) geochemical patterns simulation based on geological constrains, which helps to understand geological processes. Future researches should focus on development and application of various functions for processing geochemical data in a GIS to promote the progress of geoinformatics in both geochemical exploration and environmental studies.
