Abstract

This study deals with the most widely isolated (in terms of fragmented habitats) urban areas and the deepening of understanding over the island bio-geographic status in Seoul/Tancheon amid increased urbanization. The research was conducted in five stages, from collecting information on representative habitats and species, to designing based on humanities and social environmental factors. ① Collection of information on theories related to bird habitats in the ecological landscape conservation area, etc. ② Establish the basis for the habitat environment factors of migratory birds and social environment factors, ③ bird habitat model design implementation, ④ Determination of the design direction of habitat environment for migratory birds in the Tancheon Ecological Landscape Conservation Area, ⑤ Derivation and presentation of design for habitat environment for migratory birds in the Tancheon Ecological Landscape Conservation Area. Tancheon is designated as a place for migratory birds in the city center among 17 areas allocated as ecological and landscape conservation areas in Seoul. In this area, there are urban islands on which the biological habitats of the surrounding areas are fragmented according to physical and artificial urbanization. Therefore, among birds in the ecosystem's best predatory taxa, 4 four key species (Spot-billed Duck, Common Merganser, Black-backed Wagtail, and Great Tit) were selected. A model design of habitat for birds in consideration of the physical environment, biota, and aquatic environments of the surrounding environ based on the characteristics of the water system according to the type of habitat of the selected species, water surface, submersion, water transformation, surrounding vegetation and green space was created. It is intended to present a habitat design that integrates the bird habitat and the surrounding physical environment if the surrounding space of Tancheon is partially reconstructed through the proposed design. In addition, the minimum and maximum categories of the major fish species corresponding to the river wetland habitat were considered, and the golden frog was selected among amphibians. In designing this river of green corridors in the form of habitats in order to minimize the impact on organisms, the following were previously proposed: a planting plan, noise barrier installation planning, general planning, and various strategic planning programs. These include: 1. A bird breeding model that considers the habitat environment ecosystem to restore the bird habitat environment, 2. Minimizing pedestrian paths to reduce human interference, 3. Considering the non-interference distance of birds, construct aperches, artificial islands, stepping stones, and vegetation buffers. 4. Provide ornithologists (bird watchers) a place which provides appropriate ecology education. It is expected that the qualitative improvement of biodiversity and human coexistence will come through the sharing of the biological space of the disconnected surrounding forest habitat. Accordingly, it is expected that it will emerge as an environmental and ecological complex space for citizens and develop into a multi-biodiversity core area where not only living things such as local communities, but also human and natural organisms coexist.
