本文简要介绍了井水位同震响应特征及其力学意义，探讨了利用同震阶升区判定未来地震危险区的可能性。在此基础上分析了郯庐带中南段与其邻区井水位对汶川8.0级与日本9.0级地震的同震响应特征，指出汶川地震时同震阶升井集中出现在安徽地区，之后该区发生Ms3.8级中等地震的事实，并进一步指出日本地震后该区无一口同震阶升井，由此推测，未来一、二年内郯庐带中南段发生中等以上地震的可能性不大。
This paper briefly introduces the well water level coseismic response characteristics and its mechanical signicance, discusses the the possibility of using coseismic step uplift area to judge the future seismic risk regions. On this basis, analyzes the coseismic variation characteristics on the water level of Mid-South segment and its adjacent area of Tanlu fault belt to the Wenchuan M 8.0 earthquake and Japan M 9.0 earthquake, points out that the coseismic step shaft appeared mainly and distributed in Anhui area during the Wenchuan earthquake, afterwards this area occurred a Ms3.8 moderate earthquake, and further pointed out that there is no coseismic step shaft after the Japan earthquake, there for the risk of occurring moderate earthquakes is not obvious in the next one or two years.
