시스템 다이내믹스 기법을 활용한 미세먼지(PM10) 인과지도

Abstract

Fine dust was designated as a social disaster with top priority, a complex environmental problem, by the Ministry of Environment, Korea. in 2020. Policies to reduce fine dust from emission sources were differently implemented by city size. Previous research related to fine dust has dealt with both its impacts on health and its impacts on society as a whole. But, the studies did not consider changes in fine dust control factors, and did not employ dynamic analysis of policy factors according to city size. Therefore, this study intended to draw a causal loop of fine dust (PM10) emissions and effects using System Dynamics by city size considering policies. To reach this goal, this study has designed following research procedure: 1) to select factors that identify fine dust emission sources and the effects; 2) to investigate causal relationships between the causes and effects of fine dust; and 3) to draw a causal map of fine dust in consideration of policy variables by sectors by city hierarchy. As a result, the sources of fine dust included socioeconomic, demographic, and urban spatial variables, and the impacts of fine dust emissions due to differences in fine dust reduction policies by city size were identified in the causal map.
