摘　　要：卫星重力技术的发展使重力场观测数据趋于多样化,重力数据的融合处理已成为一个重要问题。对不同分辨率的数据融合问题进行了初步研究,详细阐述了多分辨最小二乘配置法的基本原理,推导了该方法的具体公式,并通过一个模拟算例将多分辨最小二乘配置法与传统最小二乘配置法的结果进行了比较分析。With the progress of satellite gravimetry techniques, the observation data of gravity field has become diversified. Therefore, the fusion of various gravity data has grown more important. The fusion of muhiresolution data is investigated preliminarily. The principle of multiresolution least-squares collocation （LSC） is expatiated and its formulas are deduced. The comparison between the multiresolution LSC and the traditional LSC is performed through a simulated sample.
