摘　　要：在对安徽巢湖剪切带宏观和微观变形形态进行精细分析的基础上,结合前人对断裂形态分形特征的相关研究,提出了地质体构造变形的"宏微对应"规律,认为同一个地质体构造变形系统中不同级别的构造变形之间其几何形态特征存在较好的相似性或对应性。同一个地质体变形系统中从宏观到微观有多种不同的变形形态类型,并不是所有变形形态都有宏微对应性,但具有宏微对应性的变形构造类型对整个变形系统具有特殊的重要意义。"宏微对应"规律是地质体构造变形中普遍存在的规律,可以作为宏观的大范围构造变形和局部甚至镜下的微观构造变形之间互相预测的一种理论依据,同时由于部分矿物分布与构造变形密切相关,因此这一规律在相关矿物分布的研究中也具有一定的指导意义。Based on some subtle analysis on the macro and micro structure deformation in ChaoHu shearing zone,combining the previous study on the fractal of fracture system,the macro-micro homologous law in geological body fracture system is put forward,there are fine comparability and homologous of the kinds and characters of the deformation in geometry between the macro and micro scene are recognized.The kinds and characters which are derived from one deformation are very variable and not all deformation have the characters of macro-micro homologous,but the deformation with the character of macro-micro homologous are very important for the whole deformation system.The 'macro-micro homologous' law is universal in geological body deformation and can be used as an academic measure to forecast macro and micro structure deformation in one deformation system,what is more,it also can be used to forecast the distribution of some minerals having tight relationship with the structure deformation.
