Abstract

This study aims to predict the land use demand of Seongnam-city using system dynamics and to simulate the effect of changes in family structure and land use density adjustment policy on land use demand. This study attempted to construct causal loop diagrams and an analysis model. The changes in land use demand over time were predicted through simulation results. As a result of the analysis, as of 2035, an additional supply of 2.08 km2 for residential land and 1.36 km2 for commercial land is required. Additionally, the current supply area of industrial land can meet the demand. Three policy experiments were conducted by changing the variable values in the basic model. In the first policy experiment, it was found that when the number of household members decreased sharply compared to the basic model, up to 7.99 km2 of additional residential land were required. In the second policy experiment, if the apartment floor area ratio was raised from 200% to 300%, it was possible to meet the demand for residential land with the current supply area of Seongnam-city. In the third policy experiment, it was found that even if the average number of floors in the commercial area was raised from four to five and the building-to-land ratio in the commercial area was raised from 80% to 85%, the demand for commercial land exceeded the supply area of the commercial area in Seongnam-city. This study is meaningful in that it proposes a new analytical model for land use demand prediction using system dynamics, and empirically analyzes the model by applying the actual urban planning status and statistics of Seongnam-city.

본 연구는 시스템 다이내믹스 기법을 활용하여 성남시의 토지이용수요를 예측하고 가족구조 변화와 토지이용밀도 조정정책이 토지이용수요에 미치는 영향을 모의실험하는데 연구의 목적이 있다. 이를 위해 분석모형을 설계하고 시뮬레이션 결과를 통해 시간의 흐름에 따른 토지이용수요의 변화를 살펴보았다. 분석결과에 의하면, 2035년 기준으로 주거용지는 2.08km2, 상업용지는 1.36km2의 추가 공급이 필요하고, 공업용지는 현재 공급면적으로 수요를 충족할 수 있는 것으로 나타났다. 한편, 기본 모형에서 변수값을 변경하여 세가지 정책실험을 실시하였다. 첫 번째 정책실험에서는 가구원수가 기본 모형에 비해 급격히 감소할 경우에는 주거용지가 최대 7.99km2 추가공급이 필요한 것으로 나타났다. 두 번째 정책실험에서는 아파트 용적율이 200%에서 300%로 상향하면 현재의 성남시 주거지역 공급면적으로 주거용지 수요 충족이 가능하였다. 세 번째 정책실험에서는 상업지역 평균층수를 4층에서 5층 상향하고 상업지역 건폐율을 80%에서 85%로 상향하더라도 상업용지의 수요가 성남시 상업지역 공급면적을 초과하는 것으로 나타났다. 본 연구는 시스템 다이내믹스를 활용하여 토지이용수요 예측의 새로운 분석모형을 제시하고, 성남시의 실제 도시계획 현황 및 통계치를 적용하여 모형을 실증하였다는데 연구의 의의가 있다. 향후 성남시 토지이용수요 예측 및 분석 모형의 정교화를 위한 후속연구가 이루어져야 할 것이다.
