基于长江中上游地区14个全球导航卫星系统(GNSS)测站的观测数据和重力恢复与气候实验(GRACE) Mascon数据,提出了一种基于卷积长短期记忆人工神经网络(LSTM)的水负荷位移估计方法。研究表明,在数据预处理时改正大气和非潮汐海洋负载,可明显减弱GNSS测站的非线性运动。与格林函数法相比,该方法的估计结果与GNSS真实观测值的差值标准差平均降低了20.2%。夏、秋季水负荷位移多为负值,而冬、春季则多为正值,且呈现出显著的周年和半周年周期性以及近1/3年周期变化。湖北省西南部水负荷位移振幅较大,而西部地区尤其是西北部地区振幅较小;中部地区水负荷位移普遍偏大,东部地区振幅逐渐减小。研究结果可为长江中上游地区水负荷位移的监测和分析提供新的视角。
