摘　　要：以昆明井水位记录到的同震响应为研究对象,分析该井水位的记震能力。结果表明昆明井水位同震响应过程地震波起了主要作用,响应形态为震荡型,响应能力受震级和井震距的双重控制。具体表现为对井震距小于10000 km、震级大于7.4的地震具有较强的记震能力。但同震响应振幅便不完全受井震距、震级的控制,推测其与井—含水系统以及区域应力变化有关。In this paper,the co-seismic response recorded by water level in Kunming well is taken as the research object,for analyzing the seismic recording ability of the well water level.The results show that the seismic wave plays an important role in the co-seismic response from well water level in Kunming.The co-seismic response pattern is oscillatory and the co-seismic response is controlled by both seismic magnitude and seismic distance.Kunming well water level has a strong seismic recording ability for earthquakes with magnitude greater than 7.4 and seismic distance less than 10000 km.However,the amplitude of co-seismic response is not completely controlled by seismic magnitude and distance,which is related to well-water system and regional stress variation.
