研究地震灾害的工作的重要性是极其明显的,而且也已达到迫切需要加强研究以进一步提高的程度。同时,通过震害类型及其成因的研究,可为震害预测、减轻震害提供科学依据。当然,地震造成破坏的因素是复杂的,本文主要从宁夏境内强震造成的地表破坏的类型、特点及其形成的地质、地貌条件入手,找出其地面破坏的规律。 The importance of research on earthquake disasters is extremely evident and has reached the level where there is an urgent need to intensify research for further improvement. At the same time, through the study of earthquake damage types and their causes, it can provide a scientific basis for earthquake damage prediction and mitigation of earthquake damage. Of course, the factors causing the damage caused by the earthquake are complex. This article mainly starts with the types and characteristics of the surface damage caused by the strong earthquakes in Ningxia and the geological and geomorphological conditions that have been formed, and finds out the law of ground damage.
