| 摘 要： | 本文从水力学的观点分析了新丰江水库区水力扩散与诱发地震活动的影响因素，讨论了新丰江水库区水力扩散与诱发地震活动的时空特点及其形成原因。最后用地震面积扩展法分析讨论了新丰江水库区水力扩散率的动态变化及其大地震的发展趋势。指出新丰江库区基底断裂网络是影响其水力扩散与诱发地震活动最决定的因素，也是形成新丰江水库区水力扩散与诱发地震活动时空特，点最主要的原因，并提出６．１级主震发生一年半以后，水力扩散诱发大地震的可能性不复存在。

| Abstract: | This paper analyst the influencing factors of the hydraulic diffusion and induced reservoir seismicity in Xingfengjing reservoir area by the view of hydraulics,discusses the seismic time-space features and their formed reasons and also discusses the dynamic changes of hydraulic diffusion rate and the seismic tendency in Angfengjiang reservoit area. The paper points out that the fundamental fracture network is the decided factor which influences the hydraulic diffusion and the induced reservior seismicity,and it is the main reason which forms the hydraulic diffusion and the induced seismicity time-space features and the paper points out that it is not possible that hydraulic diffusion induces the strong earthquake after one year and half of the main shock with Ms6. 1. |
