摘　　要：对数字线划图由参心独立坐标系转换到地心独立坐标系、高斯投影大地中央子午线发生变化时,引起地块面积变化的因素进行分析、计算和研究,提出了一种坐标转换后地块面积的快速算法,并对算法的准确性进行了验证。The paper analyses,calculates and research the land area change based on the transformation from independent reference-ellipsoid-centric coordinate system to independent geocentric coordinate system and gauss projection central meridian change when making digital line graphs,and puts forward a speedy arithmetic method to calculate land area after the transformation of coordinate system and validates this method.
