초록
본 연구의 목적은 연담도시화와 도시외곽 중심개발이 도시온도에 미치는 영향을 탐색적 수준에서 살펴보는 것이다. 도시 열환경 모의는 InVEST Urban Cooling Model을 사용하였다. 도시화 시나리오는 강릉시 도심부 일대를 연구대상지로 2018년 대분류 토지피복도와 대기기상자료를 이용하여 총 다섯 가지로 작성하였다. 연구결과는 다음과 같이 논의 가능하다. 첫째, 도시개발의 총량 증가는 해당지역의 냉각용량지수값을 낮추며, 평균온도값을 높이는 작용을 한다는 것이 관찰된다. 둘째, 동일한 면적의 도시화가 이루어진다면, 연담도시화 시나리오가 냉각용량지수에서 보다 효과적인 것으로 관찰된다. 셋째, 도시 열환경에는 도시화 면적이 부정적 영향을, 산림지역 면적은 긍정적인 영향을 미칠 가능성이 있음이 관찰되었다. 본 연구결과는 가능성 수준에서 논의되는 것이 적절하다.
Abstract
The purpose of this study is to examine, at an exploratory level, the impact of conurbation and urban outskirt development on urban temperature. The InVEST Urban Cooling Model is used to simulate the urban thermal environment. Total five urbanization scenarios are created using the 2018 land cover map and atmospheric meteorological data for the City of Gangneung. Findings are as follows; it is observed that (1) an increase in the total amount of urban development lowers the cooling capacity index value and increases the average temperature value, (2) if the same area is urbanized, the conurbation scenario is more effective in terms of cooling capacity index, (3) urbanization area is likely to have a negative impact on the urban thermal environment, while forest area is likely to have a positive impact. It is appropriate to discuss the results of this study at the possibility level.
