| Abstract: | By investigating the geomorphic and geologic features of the rivers in the Lianjiang water source area,it＇s known that the valley landform planar distribution in this area are longitudinal valley,latitudinal valley and oblique valley,the longitudinal section mainly are V shape and U shape.There are three basins in the joint of tributary and the master river,each basin developed three classes of terrace,have formed since 56.7±3.6Ka,24.2±2.4Ka and 0.8±0.250Ka.The valley landform,terrace feature has deep relation with crust intermittent lift of neotectonic movement,the water system is controlled by active fault,big joint and stratum occurrence strictly.Because the neotectonic movement makes the land of Gaopochang area lifted quickly,causes the source erosion of Xiaomachang river stronger,affords abundant material source for the Lianjiang master river,so it becomes the main material source area. |
