地球化学背景与地球化学基准

探讨了地球化学背景和地球化学基准的概念、含义和确定方法.认为随着地球化学的发展,地球化学背景的概念和含义都发生了很大的变化,由初期的注重其“量”到目前的关注其“质”,研究的目的不同,背景值的确定途径也不同.无论是地球化学背景还是地球化学基准,共同之处在于它们独特的参考功能,正是这种参照性质使地球化学背景和地球化学基准的研究在进行环境质量评价和环境立法时具有重要的理论意义和实用价值.

Geochemical background and geochemical baseline

The article discusses the concepts, connotations and determining method of geochemical background and geochemical baseline. With the development of geochemistry, great changes have taken place in the concept and connotation of geochemical background. In the early days, attention was paid to the "quantity" of the geochemical background, while at present the "nature" is the focal point. The method of determining geochemical background values varies with different research purposes. The common point of geochemical background and geochemical baseline lies in their special reference function. It is this reference function that makes the research on geochemical background and geochemical baseline have great theoretical and practical value in environmental quality evaluation and environmental legislation.
