摘要
地震模式受制于学术思想和科技水平,并随时间演化。研究了从"弹性回跳说"以来的演化轨跡:仅考虑震源区(断层段)→震源区和周围构造相互作用→地壳上部脆性层和深部韧性层与上地幔间的耦合→将地震视为现今大陆变形动力系统自组织演化过程的一种行为。百年演化总趋势是从震源到"动力系统"。特征为:模式时空域扩大、维数上升;从还原论、机械论到整体论、演化论;从经典力学到复杂系统理论及非线性动力学;新模式包容并超越已有模式,向大自然的本性逐渐接近。受益于地震大地测量学观测成就,关联性强的跨学科新地震模式正在探索与成长中。
Earthquake models are restricted to the academic and scientific level; further, they evolve over time. We researched the history of earthquake model evolution., models that consider only the hy- pocenter region (fault zone)→models that consider hypocenter region together with surrounding tec- tonics→models that consider upper crust brittle layer and deep crust ductile layers coupling with upper mantle→models that consider the earthquake as an activity of present continental deformation dynamic system's self-organization evolution process. The evolutionary trend is from hypocenter to dynamic system over a hundred years. Its characteristics are. time-space domain expands, dimension rises of the models; from reductionism mechanism to holism; from classical mechanics to complex system the- ory and nonlinear dynamics; new models contain and surpass old models, and are better approaching nature. Benefitting from the unprecedented achievements of seismic geodesy, strong correlativity and interdisciplinary methods, new earthquake models are developing.
