Due　to　the　complex　dynamic　of　aeolian　and　fluvial　interacted　processes　behind　the　landform　development,　most　of　previous　works　started　from　classifying　the　types　of　landscape　characterized　by　various　aeolian　and　fluvial　features.　Such　classifications　are　usually　generalized　based　on　large　geomorphic　data　set　abstracted　from　satellite　images　without　field　verification　and　dynamic　field　data.　In　this　study,　we　identified　river　banks　in　deserts　as　a　unique　geographical　unit　dominated　by　aeolian-fluvial　processes.　Three　distinct　locations　have　been　identified　as　representative　study　cases,　which　are　in　the　Keriya　River　Basin　in　the　west,　the　Mu　Bulag　River　Basin　in　the　middle　and　the　Xar　Moron　River　Basin　in　the　east　of　the　northern　China.　The　aeolian-fluvial　interaction　types　were　quantified　based　on　site　observation　and　measurement,　topographic　mapping　and　remote-sensing　image　analysis.　Dimensional　morphological　relationship　between　river　channel　and　adjacent　sand　dunes　areas　were　explored.　We　concluded　that　different　channels　are　often　associated　with　different　distributions　of　riparian　dunes.　The　quantitative　data　enabled　us　to　distinguish　statistically　four　different　types　of　landscape　in　aeolian-fluvial　dominant　environment,　namely　riverside　dunes-straight　channel,　symmetrical　interleaving　dunes-meandering　channel,　river-island　dunes-　braiding　channel,　and　grid-like　dunes-anastomosing　channel,　aiming　to　provide　compensational　information　to　current　aeolian-fluvial　interaction　studies.　The　angle　of　interaction　between　aeolian　and　fluvial　systems,　the　windward　and　leeward　sites　of　the　bank,　vegetation　coverage　and　underlying　landform　determines　the　distribution,　morphology,　scale　and　direction　of　extension　of　the　riparian　dunes.　The　results　of　the　work　study　can　provide　a　reference　for　study　of　aeolian-fluvial　interactions　at　different　spatial　scales　in　arid　region.
