从系统论出发，概述了地球化学系统内普遍存在自组织、自相关和自相似，并初步讨论了三者之间的关系：（１）自组织是自相似之源；（２）自相关可以标度自相似。自组织、自相似与自相关的有机结合势必对地球化学系统研究产生深远的影响。

Starting from systematical science, it is common that the geochemical system possesses self-organization, auto-correlation and self-similarity. Among them, there are important relationships:(1)the self-organization is the source of similarity, (2) the self-similarity may be measured by auto-correlation. The effective combination of self-organization with self-similarity and auto-correlation should make effect on the investigation of geochemical system.
