기개발도시 물순환 체계구축을 위한 저영향개발기법 도입 개선방안 : 광주광역시 상무지구를 중심으로

Abstract

LID techniques are being applied to build urban water circulation, but most of them are applied to basic urban plans such as the development of new cities and new development projects such as district unit planning. In this study, we derive LID application scenarios for establishing an appropriate water circulation system by selecting an old town. The applicability was reviewed through an effectiveness analysis. In addition, we identified problems in the LID introduction process and suggested ways to improve them, and conducted research with the following purposes.BR The target area was selected as the Gwangju Metropolitan City Sangmu District, which is an old town. The LID application scenarios were derived for establishing an appropriate water circulation system in the old town, and the effects of water balance analysis and non-point pollution sources were analyzed for each scenario. Finally, the problems of the LID introduction process were analyzed and an improvement method was proposed for establishment of the water circulation system.BR Urban environmental problems, such as urban development in an old town, are expected to be more diverse and increase, and one such problem will include environmental issues due to changes in water circulation. The need for LID techniques to solve these water circulation distortion problems will continue to increase. It is necessary to apply LID techniques to restore water circulation in the old town, as well as legal and institutional improvement methods that can support them.
