Abstract

The definition of urban forest is described as all forest and trees except the Natural Parks throughout whole territory in Urban Forest Act. But the concept of urban forest in the law differs from general awareness by Korean citizen and from definitions of other countries. For discussing such differences of urban forest definition, it was tested how much urban forest area would be changed according to the various definition of urban area. The urban area was defined to be four scenarios in this study in consideration of "urban area" by National Land Planning and Utilization Act (NLPUA), 300m buffered boundary from the "urban area" proposed by World Health Organization (WHO) and forest watershed area. In the scenario 1, including forest watershed intersected with "urban area" by NLPUA, urban forest area was estimated at 1.83 million ha in which urban forest area per person was 386㎡. In the scenario 2, including forest watershed intersected with 300m buffered boundary from the "urban area" by NLPUA, urban forest area was estimated at 1.92 million ha in which urban forest area per person was 405㎡. In the scenario 3, including forest watershed intersected with "urban area" placed within administration boundary (Eup·Dong districts), urban forest area was estimated at 1.08 million ha in which urban forest area per person was 230㎡. In the scenario 4, including forest watershed intersected with 300m buffered boundary from "urban area" placed within administration boundary, urban forest area was estimated at 1.20 million ha in which urban forest area per person was 256㎡. Therefore, the boundary of urban area should be agreed clearly prior to defining the urban forest area for avoiding unclear area calculated according to different definitions.

우리나라 도시숲은 「도시숲 등의 조성 및 관리에 관한 법률」에 의거하여 자연공원을 제외한 모든 산림과 수목으로 정의되고 있으나, 일반적인 인식으로서의 도시 내 존재하는 숲의 개념과는 이질성이 있다. 본 연구에서는 도시숲을 "도시 내에 존재하는 산림과 수목"으로 규정하였으며, 도시의 경계를 설정하기 위한 시나리오를 제안하고 그에 따른 도시숲의 면적 변화를 모의하였다. 법률상 도시지역의 정의, WHO에서 제안한 주거지로부터 도시숲에 접근 가능한 거리(300m), 산림유역을 고려한 네 가지 시나리오를 설정하여 각 시나리오에 따라 도시숲의 양적 분포를 분석하였다. 첫 번째로 "용도지역상 도시지역"의 최외곽 경계와 연접하는 산림유역까지를 도시숲 경계로 규정한 경우, 도시숲 면적은 약 183만ha, 1인당 도시숲 면적은 약 386㎡로 분석되었다. 두 번째로 "용도지역상 도시지역"의 최외곽 경계로부터 300m 이내까지 도시로 규정하고 해당 경계와 연접한 산림유역 내에 존재하는 숲을 도시숲으로 규정한 경우, 도시숲 면적은 약 192만ha, 1인당 도시숲 면적은 약 405㎡로 분석되었다. 세 번째로 "행정구역 상 읍·동 지역"내 "용도지역상 도시지역"의 최외곽 경계와 연접하는 산림유역까지를 도시숲 경계로 규정한 경우, 도시숲 면적은 약 108만ha, 1인당 도시숲 면적은 약 230㎡로 분석되었다. 네 번째로 "행정구역 상 읍·동 지역" 내 "용도지역상 도시지역"의 최외곽으로부터 300m 경계와 연접하는 산림유역까지를 도시로 규정한 경우, 도시숲 면적은 약 120만ha, 1인당 도시숲 면적은 약 256㎡로 분석되었다. 이렇듯 도시의 정의에 따라 도시숲의 면적이 다양하게 추정될 수 있기 때문에, 국가통계를 집계하기 위해서는 도시에 대한 정의가 먼저 정립되어야 하고, 그에 따라 현실적·과학적 분석에 근거하여 도시숲의 면적이 산출되어야 한다.
