摘　　要：海洋表层沉积物元素地球化学测量数据集往往由多来源数据组成。由于测试单位、测试设备、测试技术方法等的不同,造成这类数据存在多源性差异。以Si元素为例尝试采用相邻点对回归模拟法对不同来源数据进行平差和图幅集成,结果表明相邻点对回归模拟法不仅能够消除数据之间存在的系统误差,很好地反映元素在整个区域的分布情况,还能够将数据校正到更加合理的数值范围。Element geochemical data of marine surface sediments from investigation program usually derive from multi-sources which are measured by different institutions, using different instruments and methods. This paper focuses on element of Si. The regression simulation of adjacent pair-points were used for adjus- ting of systematic error and integrating of mappable units. The results show that this method could suc- cessfully remove the systematic error and resulted in a good element distribution pattern and more reasona- ble value ranges.
