【摘要】 以非线性思想研究了榆次地区地裂缝和构造、地貌、地震的几何形态特征,计算了它们的分维值。发现地裂缝与断层的分维值非常接近,而且地裂缝分维值小于断层分维值,说明地裂缝形态和断层形态相似,同属于剪切走滑性质,但地裂缝的复杂程度和活动性都小于断层。总结榆次地区断层、地裂缝、地震和地貌分维值的关系,可知当地的地裂缝、地貌形态和地震活动都受到断层活动的控制。更多还原

【Abstract】 Earth fissure and its environment is a nonlinear systemThe timespatial structure of Yuci earth fissure and its environment is discussed by using the fractal theoryThe fractal of earth fissure, fault,earthquake and physiognomy of Yuci are calculated and compared The author concludes that the earth fissure and its environment have the selfsimilarity characterIts fractal is 121,similar with fault′s fractal which is 11905The connection between earth fissure and earthquake is analyzed and both of them are controlled by tectonic activityAccording as the descend of the fractal of fore earthquake and the ascent of the fractal of back earthquake,the forecast of earth fissure by comparison of fractal of earthquake with that before and after the form of earth fissure is studied更多还原
