| 摘 要： | 利用侵蚀流域的地貌信息熵理论定量研究了东北地区的构造活动和区域稳定性，结果表明，熵值小于０．２的区域与现代构造活动的区域相一致，熵值的高梯度带及其走向畸变部位与大地震的位置具有某种对应关系。总体分布状态与新活动较强的构造格架可能有某种成因联系．

| Abstract: | Making use of the theory of morphological information entropy for erosion-al basin,tectonic activity and regional stability in Northeast China have been studied in thispaper.The results show that the region in which the entropy is less than 0.2 is consistentwith modern tectonic activity area,and there exists some corresponding relation betweenhigh gradient belt and location of strong earthquakes. |
