摘　　要：Surfer 8.0是现行绘制等值线的主要工具,将其与GeoHydrology(长江水文泥沙信息分析管理系统)数据分析和图形文件标准化相结合,应用于河道冲淤分析工作中。介绍了数据处理格式,成图方法。根据2009年4月和12月长江陆溪口河段邱家湾险工段的实测地形数据文件,建立网格,绘制河道冲淤渐变图,并对冲淤量进行了计算与分析。验证表明,生成的图形直观准确,并能够提高河道冲淤分析的工作效率。Surfer8.0 is the main tool for drawing isoline at present,and it is combined with GeoHydrology for data analysis and graphic file standardization in hydrological analysis of channel scouring and siltation.We introduce data processing formation and graph producing method according to in-situ terrain data file of Qiujiawan danger section of Luxikou reach of Yangtze River in April and December of 2009 respectively.The grid and gradual change graph of channel scouring and siltation were established.It is shown that the produced graph is correct,reliable and visual,which increases the work efficiency of channel scouring and siltation analysis.
