초록

도시 지역의 열 환경을 파악하기 위해 열 플럭스를 추정하고자 하는 연구들이 많이 진행되어 왔다. 현재 다양한 방법을 통해 현열 플럭스가 추정되고 있으나 각 방법 간의 차이를 비교하는 연구는 매우 미흡한 실정이다. 따라서 본 연구는 대표적인 두 가지 현열 플럭스 추정 방법을 통해 동일한 대상지의 현열 플럭스를 추정하고 그 결과를 비교하여 방법 간의 의의와 한계를 확인하고자 하였다. 연구 결과 열수지 방정식 방법을 통해 현열 플럭스를 추정할 경우 해상도면에서 큰 장점을 가지나 도시 지역의 특징 중 하나인 인공열을 반영하지 못해 현열이 과소추정될 수 있음을 확인할 수 있었다. 물리식을 기반으로 추정할 경우 상대적으로 오차가 작고 인공열의 반영이 가능하나, 시간 및 공간 해상도에 있어 한계가 있음을 확인하였다. 두 방법은 인공열이 많이 발생하는 공업지역에서 가장 큰 차이를 나타냈으며 그 차이는 평균 약 135 W/m2 , 최대 400 W/m2 로 나타났다. 반면 녹지 및 수변공간은 약 20 W/m2 로 두 방법 간의 차이가 매우 작은 것을 확인할 수 있었다. 두 방법 간의 결과가 도시 지역에서 유의미한 차이를 보이는 만큼 향후 연구 목적에맞는 방법을 선택할 필요가 있다.

Abstract

In orderto understand the urban thermal conditions, many studies have been conducted to estimate the thermal fluxes. Currently sensible heat fluxes are estimated through various methods, but studies about comparing the differences between each method are very insufficient. Therefore, this study try to estimate the sensible heat flux of the same area by two representative estimation methods and compare their results to confirm the significance and limitation between methods. As a result of the study, the heat balance methods has a great advantage in terms of resolution but it can not consider the anthropogenic heat flux, so sensible heat flux can be underestimated in urban areas. When estimating based on physical equation, anthropogenic heat flux can be considered and the error is relatively small, it has a limitations in time and space resolutons. The two methods showed the largest difference in industiral areas where anthropogenic heat fluxes are high, with an average of 135 W/m2 and a maximum of 400 W/m2. On the other hand, the green and water have a very small difference with and average of 20 W/m2. The results between two methods show significant differences in urban areas, it is necessary to select a suitable method for each research purpose.
