本文利用1953—1955年,1976—1980年两期精密水准测量成果编绘的垂直形变图,在苏鲁皖豫地区形变的构造背景作了初步分析。认为区内存在着郯庐带临沂—嘉山段和豫鲁交界两个构造形变异常区。全区形变主要受北西西、北西和北东向断裂控制。郯庐带的现今运动具有明显的分段特征。 Based on the vertical deformation maps compiled from the precision leveling surveys of 1953-1955 and 1976-1980, this paper makes a preliminary analysis on the tectonic setting of the deformation in the areas of Sulu-Anhui-Henan region. It is believed that there are two tectonic deformation anomalies in the area of ​​Linlu-Linyi-Jiashan section and the junction of Henan Province and Henan Province. The deformation of the whole region is mainly controlled by faults in North West, North West and North East. The current movement in Tanlu belt has obvious segmental characteristics.
