The formation of Sajapyeong Alpine Wetland was influenced by factors of drainage basin and its geology, and fire-shifting cultivation. Sajapycong drainage basin had a narrow outlet, Sijeon-cheon in it flowed relatively slowly. Bedrock in basin was weak to mechanical weathering, many rock detritus were, produced. Deforestation for reclamation using fire accelerated topsoil loss. Thus much sediments was supplied to Sijeon-cheon and deposited in the channel bed, and wetland was formed on channel marginal footslope. In Sajapyeong moor were Gullies formed along road. Because they blocked sediments and throughflow transferring into moor, moor became dry land. In order to prevent this drying, we have, to raise water level of a drain ditch to level of weathered bedrock to transfer throughflow into moor, modify the shape of ditch to be naturally irregular, and construct large boulders step on the Sijeon-cheon bed to prevent from lowering of its bed.
