Abstract

Increasing impervious surfaces can cause various physical and mental illnesses as well as further problems like deterioration of the thermal environment and disconnection of the water circulation system in the downtown area. This study is intended to suggest baseline data for the future creation or remodelation of large-scaled urban parks in consideration of human health on the aspect of climate by analyzing air ions condition and correlation analysis between air ions and meteorological elements depending on distances from the center in the urban park. The study site was divided into four types by distances from the center of Olympic Park in Songpa-gu, Seoul, then classified as A and B. After selecting 80 points to record, land coverage and vegetation status were investigated, and then meteorological elements and air ions were measured. First, the green space rate by section is A section Center (90%)> Inner (70%)> Outer-inner (10%) = Outer (10%), B section Center (100%)> Inner (60%)> Outer- In order of inner (30%)> Outer (0%). Second, for weather factors, the temperature was analyzed by Outer (24.18℃) > Outer-inner (22.90℃) > Inner (22.43℃) > Center (21.719℃). For relative humidity, center (46.49%) > Inner (43.36%) > Outer-inner (42.41%) > Outer (38.53%) was analyzed. Third, In the case of cations in the air ions, Outer(435.71ea/㎤) > Outer-inner(415.16ea/㎤) > Inner (389.46ea/㎤) > Center (352.64ea/㎤). In the case of negative ions, Center (569.72ea/㎤) > Inner (499.83ea/㎤) > Outer-inner(410.58ea/㎤) > Outer (292.02ea/㎤). It was analyzed to increase toward Center, and analyzed to decrease with increasing distance from road. For the Air ion index, it was analyzed as Center (1.67) > Inner (1.31) > Outer-inner (1.08) > Outer (0.71). Negative irons was analyzed to increase when its measuring points close to the center and decrease with shortening distance to the road. Fourth, as a result of correlation analysis, positive(+) correlation is negative ions and ion index. These were measured to increase as the recording points closing to the center of the park from the road. The negative(-) correlation is temperature, solar radiation, and positive ions. These increased as getting closer to the road.

불투수포장면적의 증가는 도심지 내 열환경 악화, 물순환체계 단절 등의 문제점과 더불어 인간의 여러 가지 신체적·정신적 질병에 원인이 되기도 한다. 이에 도시공원 내 거리에 따른 공기이온 실태와 거리별 기상요소 및 공기이온과의 상관성을 분석하여, 향후 도심지 내 대규모 도시공원 조성 혹은 리모델링에 있어서 기후적 측면의 건강성을 고려한 도시공원 조성의 기초자료로 제시하고자 하였다. 연구대상지는 서울시 송파구 올림픽공원을 대상으로 거리에 따라 4개 유형으로 구분한 뒤, 구간을 A, B로 분류하였다. 측정지점은 80지점을 선정한 후 토지피복 및 식생현황을 조사한 후 기상요소, 공기이온을 측정하였다. 첫째, 구간별 녹지율은 A구간 Center(90%) > Inner(70%) > Outer-inner(10%) = Outer(10%), B구간 Center(100%) > Inner(60%) > Outer-inner(30%) > Outer(0%) 순이었다. 둘째, 기상요소의 경우 기온의 경우 Outer(24.18℃) > Outer-inner(22.90℃) > Inner(22.43℃) > Center(21.719℃)으로 분석되었으며, 상대습도의 경우 Center(46.49%) > Inner(43.36%) > Outer-inner(42.41%) > Outer(38.53%)으로 분석되었다. 셋째, 공기이온 중 양이온의 경우 Outer(435.71ea/㎤) > Outer-inner(415.16ea/㎤) > Inner(389.46ea/㎤) > Center(352.64ea/㎤)의 순이었으며, 음이온의 경우 Center(569.72ea/㎤) > Inner(499.83ea/㎤) > Outer-inner(410.58ea/㎤) > Outer(292.02ea/㎤) 순으로 Center로 갈수록 증가하는 것으로 분석되었으며, 도로와 가까워질수록 감소하는 것으로 분석되었다. 이온지수의 경우 Center(1.67) > Inner(1.31) > Outer-inner(1.08) > Outer(0.71)으로 분석되었다. 넷째, 상관성 분석결과 정(+)의 상관인 것은 음이온, 이온지수로 도로로부터 공원 Center로 갈수록 증가하는 것으로 분석되었으며, 부(-)의 상관인 것은 기온, 일사량, 양이온으로 도로와 가까워질수록 증가하는 것으로 분석되었다.
