【摘要】 通过对沂沭断裂带地区2010~2012年共6期重力场资料进行动态差分,和相对于2010~2012年6期基准的动态变化分析,得到沂沭断裂带重力场的变化特征为:沂沭断裂带重力场呈现明显的季节性变化,即每年的3月与8月重力场存在反向变化,其季节性变化与降水量相关。更多还原

【Abstract】 We did the dynamic difference on the 6 periods of gravity data from 2010 to 2012 in Yishu Fault zone,and analyzed their dynamic variation relative to 6 periods of reference from 2010 to 2012 to obtain the gravity field variation characteristics of Yishu Fault zone. The result show ed that the gravity field of Yishu Fault zone appeared the significant seasonal variation,w hich w as related w ith rainfall,and there w ere a reverse variation on March and August in each year.更多还原
