| 摘 要： | 本文利用1971—1986年山东全省多期复测水准及部分测距成果讨论了本省的地壳形变特征。结果表明:以沂沭带为界,鲁东块体显示整体抬升,而鲁西块体虽以上升为主,但内部明显存在着形变差异运动。期间地壳垂直形变速率不高,一般不超过±3mm/年。近期构造运动显示继承性特点,地壳上升和下降的分界线与断裂相吻合。沂沭断裂带形变北强南弱。沿该带北西向益都、苍山-尼山断裂两侧形变差异较大,活动相对强烈,故对这两条断裂及其与沂沭带交汇处应加强监测。

| Abstract: | Based on the data of relevelling and electromagnetic distance measuring across the Yishu fault zone on two networks from 1971 to 1986, the characteristics of crustal deformation in the area are analysed in this paper. The results show that the rates of uplift in hilly area and subsidence in plain area are generally less than 3mm/year, the division line between uplifted and subsided region is along fault, the crustal movement is successive and the tectonogeomorphology development is controlled by the fault during the period.The value of deformation in north of Yishu fault zone is two times larger than that in south. There are obvious differential movement in two sides of the Yidu and Cang-Nishan fault at NW direction and the faults across Yishu fault zone. It is pointed out that the crossing region of the faults should be pay more attention to. |
