LID기반 지구단위계획 수립기법 개발 및 LID 효과 모의

저영향개발 기반 지구단위계획 기법을 개발하고 효과를 모의했다.

This study aimed at developing LID-based district planning techniques, and simulating effects of LID-based district planning. Analyses were progressed with the following order. First, establishing process and principles of LID-based district planning were set up through analyses on related literature, and LID-based district planning technique (proposal) was deduced. Second, FGI was executed to develop the technique. To secure its objectivity, FGI (Focus Group Interview) was progressed three times. Third, LID-based district planning was established by selecting the object place, and LID effects were simulated. Simulation was made by using multilateral impact assessment tool.

Research results are as follows. First, LID-based district planning technique was developed. Principles were derived from ‘Preventing flood damage,’ ‘Securing good environment,’ and ‘Minimizing developmental impact area.’ Establishing procedures were composed of steps like basic survey, comprehensive analyses, basic design, plans by section, and each step had detailed phases. Second, a fact was verified that LID-based district planning technique reduced non-point pollution source and rainfall runoff and had sufficient ability in achieving environmental performances which enhanced ecosystem through a simulation on LID-based district planning effects.

Third, LID-based district planning can be evaluated as a comprehensive plan which achieves environmental performances and ensures development of areas as well.
