地貌單位線被看作是流域上各水質點在弱相互作用下,到達流域出口匯流時間的頻率分佈。對於一個典型的山坡型網格單元,匯流路徑由兩部分組成,即坡地部分和河道部分,為了得到匯流時間,必須首先確定匯流速度。坡地和河道的匯流速度隨著區域位置而變,並且必然與坡度有關,因此,可首先計算流速的空間分佈,進而得到匯流時間的空間分佈。Through the field research of landform and cultural sites in guanting basin of the upper reaches of the yellow river in qinghai province, the authors analyzed the structure of the second terrace of guanting basin and concluded that the second terrace came into being in middle holocene
