摘　　要：选取台湾地震区1900—2009年5级以上地震,对台湾地震区作应变释放速率分析。结果表明,台湾地震区应变释放速率存在约3年的周期性变化,还可能存在约24年的周期变化。台湾地震区应变的积累和释放呈现ΣE^(1/2)=A+Bt的函数关系。The strain energy release rates of earthquake area in Taiwan were analyzed from M≥5.0 earthquake data from 1900 to 2009. The results show that there is peroidical change of strain energy release rate by three years, or may be about 24 years. The strain energy cumulation and release of the earthquake area in Taiwan show the function relation ：∑√E=A＋Bt

关 键 词：台湾地震区 应变释放速率 周期 函数关系 动态平衡
