A Study on Planting Landscaping Plants according to the Characteristics of Urban River Sections - A Case Study on Godeokcheon(Stream) in Seoul -

The present study was conducted to assess the adequacy of landscaping plants in city streams by investigating the species and growth status of landscaping plants, taking Godeokcheon in Seoul Metropolitan City as an example. The stream structure related to the planting ground and the impact of flood damage were analyzed. The adequacy of the planting species was analyzed based on the native species and moist land-inhabiting plants presented in the preceding study results. The adequacy, depending on the planting location and planting form, was analyzed using the growth states of adaptive and nonadaptive species by river topography. The planting location of those along the waterfront was the best, followed by the plants on waterside hills and embankment slopes. It is thought that the adaptability of dryland-inhabiting plants increased as the soil dried due to the impervious pavement of surrounding bikeways and trails. The species adequate for embankment slopes are thought to be native species and dryland-inhabiting plants. It is thought that, for waterside hills, the planting rate of wetland-inhabiting plants should be increased, and for waterfronts, the planting rate of dryland-inhabiting plants should be decreased. As for the planting form, the growth state was the best when mixed species were planted and the worst when other plants appeared. For city streams, the planting rates of native species and wetland-inhabiting plants should be increased, and adequate plant species for each location should be selected.
