摘　　要：针对重力资料应用于地质体的边界定位问题进行了系统的研究,通过大量二维、三维模型的正演计算,统计分析了重力各异常特征值点边界定位的误差,最后给出了每种方法精确定位边界的应用前提。A systematical study of mapping boundaries of geological bodies by using gravity data has been made in the paper. With a large quantity of forward calculations on 2D and 3D models, the errors of locating geological boundaries based on characteristic values of gravity anomalies have been analyzed, and with conditions suitable for each method of boundary mapping summarized.

关 键 词：重力资料 边界定位 定位误差 异常特征值
