平行排水系統-
The main characters of the river - valley landforms are followed : the outstandingly longitudinal range - gorge landforms constitute the unique view of three parallel rivers ; the relative highness difference of the landform is great and the river valley cut deeply ; the formation and evolution of the river - valley landforms are obviously controlled by the geological structure ; the landforms types and the various characters of the landforms combination in the drainage area are prominent ; the geological environment has relatively strong frangibility ; the branches riverhead of the river - valley mostly come from high mountains and lakes, and the river - valleys of the branches along the banks have disproportional distribution
其河谷地貌的主要特徵有：突出的縱向嶺谷地貌，構成了少有的三江併流奇觀；地貌相對高差大，河谷深切；河谷地貌形成演化發育明顯受地質構造控制；流域范圍內地貌類型和地貌組合多樣化特徵突出；地質地貌環境具有較強烈的生態脆弱性；河谷支流水源多發源於高山湖泊，兩岸支流河谷分佈不均衡。 -
It is found that the automatic detection of drainage networks from digital elevation models is affected by flat areas and closed depressions. a variety of methods have been proposed to treat these two features, but it can be seen that the flat areas and closed depressions are processed only after they have been created, so that many spurious and parallel drainage courses are generated
數字高程模型（ dem ）已在分散式流域水文模型中得到了越來越廣泛的應用，但dem中的閉合窪地和平坦區域影響著流域河網的自動提取。目前已提出好多方法來處理這兩種地形，但均針對已經形成的dem單元網格進行處理，結果往往生成偽河道及平行河道。
