순천동천의 수변공간 데이터 기반 횡적연속성 평가

The lateral connectivity of Suncheon’s Dong stream was evaluated based on landside,waterside, and levee data of the river. A total of six items was evaluated, crosssectionalstructure, vegetation cover ratio, connecting waterway gate, levee slopes,urbanized area ratio and wetland area ratio. Among the items, the connectivity washigh in the following order: cross-sectional structure, urbanization area ratio, andlevee slope. In a total of 16 survey areas of Suncheon’s Dong stream, one, 12, andthree areas were evaluated as continuity, damaged, and discontinuity respectively. The downstream section was evaluated as one continuity and three damaged, thelower-middle stream section was evaluated as one damaged and three discontinuity,and the upper-middle stream and upstream sections were evaluated as eightdamaged. The cross-sectional structure, vegetation cover ratio, levee slope, andurbanized area ratio had low lateral connectivity in the lower-middle stream surveysection, while the wetland area ratio had high lateral connectivity in the downstreamsurvey section. The lateral connectivity evaluation results of the river aquaticecosystem in Suncheon’s Dong stream can be used as basic data that is helpful infuture ecological river management policies.
