从卫片线性体的统计规律看辽南地区的构造特征

The Tectonic Features of South Liaoning Area Based on Statistical Law of Linear Mass of Satellite Photographs

根据对辽南地区卫片线性体的量测统计资料绘成的线性体等密度图、线性体优势方向分布图等资料,可将辽南地区分成南北两个各具特点的地质构造单元。这种划分与震源机制解相吻合,也与莫霍面的起伏形态基本一致。由此可以认为,线性体的统计规律能够反映地下深部的构造概貌。

By measuring and calculating linear mass of satellite photographs in South liaoning area,contoured diagram and perferred orientation distribution diagram of linear mass and rose diagram are drawn.There diagrams show that Zhanghe-Wa- fangdian-Changxing island divides South Liaoning area into two parts Northand South, which have features of geologic-tectonic unit respectively.This division not only fits with focal mechnism solution but also makees it clear that statistical law of linear mass is similar to undulating forms of Moho.So a conclusion is obtained that statistical law of linear mass can reflect structural general conditions deep in the earth.
