Environment-ecological planning for development of the seoul eco-city

This study was carried out to establish the direction of environment-ecological planning for the Eco-city through a survey to determine Seoul's environment-ecological status. The survey focused on entropy, water circulation and biological diversity. First the temperature rise may be continued by a high ratio of commercial areas developed with high density in terms of entropy. Second the underground development in high density built-up areas and the high ratio of impermeable pavement were analyzed as water- circulation. Lastly, although the ratio of forest and river biotope was high, those were distributed in the suburbs of Seoul and were artificially established. In addition, the damp areas which had critical functions as habitats in the city were distributed on a small-scale. Therefore, as the direction of energy circulation plan, 7 detailed planning items were required as follows: the improvement of roadside's trees and green spaces, the formation of brook street, tree-planting in the school's playground, an extension and new formation of children's park green space, tree-planting around public institutions and religious facilities, tree-planting on roofs and walls, an increase in green space around apartment complexes and the establishment of environment-ecological planning. In terms of water circulation; ecological restoration of artificial rivers, security of rainfall reservoir and establishment of residential area with satisfactory water circulation were suggested. Also, improvement plans for the biological diversity must be established by classifying into the three parts; the security of the biological habitats, the formation of urban ecological axis and the activation of ecological culture.
