摘要
文章简要地回顾了多目标区域地球化学调查与生态地球化学评价的发展历史,以及近年来多目标区域地球化学调查样品测试方法及质量监控方面取得的主要成就。指出随着生态地球化学评价逐渐成为研究的重点和核心,作为关键支撑技术的分析测试面临重大机遇和挑战:一是要求分析测试具有更高的准确度和精密度,以满足区域地球化学编图、环境监测及变化研究的需要,建议以现有54项指标分析测试方法及质量监控体系为基础,进一步提高某些介质及测试指标的分析测试水平;二是要求开发形成能满足多介质分析、多指标测定、经济有效的一整套分析测试方法体系,以适应生态地球化学评价的需要。
The paper briefly reviewed the development history of Multi-purpose Regional Geochemical Survey（MRGS） and Ecosystem Geochemistry Assessment（EGA） in China,and pointed out the main technical progress in sample analysis and analytical quality control achieved over the past decade.It was demonstrated that geochemical analysis will face great opportunities and challenge with the EGA is becoming the emphasis and focus of the MRGS study.To keep up with the requirements from regional mapping and eco-geochemical assessment,new measurement techniques and methods with higher accuracy and high precision need to be developed.Also a systematic analytical methodologies need to be established in order to meet the demands from multi-medium analysis and multi-index analysis.
