摘　　要：不同地质体的曲率特征有所差异。针对断层、窄河道、宽河道进行了仿真试验,根据仿真试验结果确定了断层、河道的识别原则。利用改进后的曲率算法计算了XX地区和YY地区最大正曲率和最小负曲率属性。并根据提出的识别原则对XX地区的断层和YY地区的断层及河道进行了识别,取得了很好的效果。试验结果表明,最大正曲率与最小负曲率的有效结合可以很好地识别断层与河道,并且改进方法有效地修正了误差。Curvatures of the different geological characteristics were different.Simulation tests were conducted on faults,narrow channels and wide channels,according to the simulated results,the fault,channel identification principles were determined.The improved algorithms were used to calculate the maximum curvatures and minimum negative curvatures of the XX and YY Regions.According to the proposed recognition principles,identification was performed on faults from XX Region of and faults and channels from YY Area and good results were achieved.Experimental results show that the effective combination of maximum positive curvatures and minimum negative curvatures can identify the faults and the channels well,and the improved algorithm effectively improvd the error correction.
