摘　　要：利用山东地区2010—2012年6期流动重力测量资料,研究了鲁南网重力场的变化特征。结果表明重力场呈明显的季节性变化,即每年的3月与8月,重力场存在反向变化,变化幅值相近;季节性变化与降水有关。The gravity field changing characteristics of Lunan zone are researched by calculating difference and integral adjustment of gravity data（6 groups in total from 2010 to 2012） in Shandong area. The research shows that the gravity field of Lunan zone varies with the seasons. The gravity field changes in March is opposite to which in August, and the variation of gravity field trends are highly consistent. It is found that the seasonal variation is relevant with rain.

关 键 词：山东地区 重力场 平差 季节性变化 降水量
