택지개발 우선순위 결정모형 정립 및 청주시 사례적용

택지개발 시기와 입지의 우선순위를 정하는 모형을 만들고 청주에 적용했다.

Korea's zoning system, which has failed to control the timing and location of development, is not fully equipped for the reasonable land-use, and so results in the haphazard development. The purpose of this thesis is to construct a priority decision model, which can forecast the timing and location of the land development for residential areas, as a part of urban growth management, and to apply the model to Cheongju. The priority decision model for residential areas consists of 5 steps. Step 1 is to estimate the land demand by phase based on the forecasted population and land use density.

Step 2 is to extract the available land by subtracting unavailable land for residential development from the total planning area. Step 3 is to subdivide the available land for residential development into the development units(DUs). Step 4 is to designate the priority to each DU, and step 5 is to decide the timing of each DU. In the result of applying the model to Cheongju, the stability of the model is examined by the correlation and sensitivity analysis. Each rank of the DUs is highly correlated at 0.01 significant level, as the correlation coefficient of Kendall's Tau-b is 0.843 and the coefficient of Spearman is 0.964 in Cheongju.
