The river patterns of the study area were analyzed by the latest channel pattern discrimination in the last glacial maximum and deglaciation of the Late Pleistocene. The hydrology, sediment, environment parameters of the ancient channel in the study area, width-depth ratio F =22.22, suspended sediment concentration M =10.10%, channel curvature P =1.52, meander wavelength L =

然后应用最新河型判别方法，分析判别晚更新世末次盛冰期和冰消期研究区埋藏古河道的河流类型为辫状型；并分析得到研究区古河道的宽深比（ F ＝22.22）、悬移质含量（ M ＝10.10％）、河道弯曲率（ P ＝1.52）、河曲波长（ L ＝1 647 m）等古水文泥沙环境参数分类指标。
