        방위에 따른 벽면녹화식물의 생육 비교

        김다윤,조용현,손인기,김윤호,Kim, Da-Yoon,Cho, Yong-Hyeon,Son, In-Ki,Kim, Yoon-Ho 한국조경학회 2021 韓國造景學會誌 Vol.49 No.5

        도시는 건축물의 과밀화로 지표면과 함께 녹지의 면적 또한 점차 줄어들고 있으며, 도시기후와 도시생태계에 악영향을 미치고 있다. 그러나 녹지의 중요성은 점차 증가하고 있으며, 지표면과 함께 수직면을 활용한 벽면녹화의 중요성도 커지고 있다. 하지만 방위와 관련된 국내 벽면녹화 지침과 제도에서 방위별로 식재를 제한하는 경우가 있음에도 불구하고, 연구를 통해 실제 8방위별로 식물의 생육 차이가 있는지 알아본 연구는 전무하였다. 따라서 본 연구는 실제 벽면녹화를 도시에 적용하기 위해 방위별 식물생장 특성을 비교분석하였다. 실험은 2020년 5월부터 9월까지 진행하였다. 우선, 8방위 벽체 3개를 제작하여 담쟁이덩굴(Parthenocissus tricuspidata), 송악(Hedera rhombea), 금빛줄사철(Euonymus radicans cv. Aueonmarinata Rehd) 식물3종을 각 벽체에 식재 후 주1회 온도, 조도, 식물의 길이를 측정하였다. 연구결과, 담쟁이의 경우 북향에서 생육이 왕성하였고, 송악과 금빛줄사철은 남향에서 생육이 왕성하였다. 식물 3종 모두 6-7월에 생육이 왕성하였으며, 담쟁이는 초장생육이 왕성하였고, 8월에 모든 벽면을 100% 피복하였다. 송악은 초장생육속도가 낮았으며, 피복률 또한 평균 45%로 낮게 나타났지만, 식물3종 중 지표면의 피복률은 송악이 가장 높았다. 금빛줄사철은 초장생육속도가 낮았으며, 최종적으로 북, 북서향을 제외한 벽면을 100% 피복하였다. 벽면녹화에 사용되는 모든 식물이 동일하게 생장하지 않으며, 방위로 인한 영향보다 식물 생육 특성에 따라 생장 차이가 있다는 것을 알 수 있었다. 따라서 식물생육의 특성을 파악하여 방위별 알맞은 식물을 식재하는 것이 좋을 것으로 판단된다. Green areas and the area of available horizontal surfaces are gradually decreasing due to the overcrowding of buildings. It is adversely affecting the urban climate and ecosystem. However, the recognition of the importance of green areas is gradually increasing. As a result, the importance of wall greening using vertical surfaces is growing. However, despite the fact that domestic wall greening guidelines and institutions related to orientations restrict planting. there was no study to determine whether there were actual differences in plant growth due to orientations. Therefore, this study compared and analyzed the plant growth characteristics by orientations to apply actual wall greening to cities. The experiment was conducted from May to September 2020. First of all, three octave walls were constructed to measure the temperature, the illumination, and the length of the plants once a week. The plants included Parthenocissus tricuspidata, Hedera rhombea, and Euonymus radicans cv. Aueonmarinata Rehd plants. As a result of the study, Parthenocissus tricuspidata was prolific in the north, and Hedera rhombea, and Euonymus radicans cv. Aueonmarinata Rehd plants were prolific in the south. All three types of plants were prolific in June-July, and the Parthenocissus tricuspidata was prolific in grass-growing, and in August, all the walls were 100% covered. Hedera rhombea had the lowest rate of herbaceous growth, and the vertical coverate was also lower at an average of 45%, but among the three plants, the sheath of the horizontal surface coverate was the highest. Euonymus radicans cv. Aueonmarinata Rehd was low in the speed of herbaceous growth, and finally, the walls were 100% covered except for the north and northwest directions. It was found that not all plants used for wall greening show the same growth, and the difference in growth varies more depending on plants than the effect of orientations. Therefore, it is better to identify the characteristics of plant growth and plant suitable plants for each directions.

        Maxent 모델을 이용한 호박벌과 양봉꿀벌의 수분 잠재환경 비교 분석 - 서울시를 중심으로 -

        The honey bee has a crucial ecological status for maintaining the natural ecology system. Pollination mediations by honey bees are recognized as an efficient way to enhance the quality of biological diversity and green areas in the nature and the urban ecological system. However, the population of bee around the world is decreasing and we do not know exactly how bees react to the physical environment in the urban area. This study is a basic research for the improvement of pollination services in the Korean urban ecological system. It aims to induce and review environmental variables which have high relations with the activities of pollination mediation insects in the urban area. The study estab lished a Maxent model using five urban environmental variables that reflect the ecology of Bombus ignitus and the place information where Bombus ignitus appears in 18 spots of Seoul city, and compared with previous research results on Apis millifera . Bombus ignitus preferred places with more natural environments such as mountain forest areas and vicinities of streams. They preferred Stratified Tree Area the most among the vegetation types existing in the urban area. Comparing chicken models, both species saw their response value drop as the building coverage rose. In the case of Apis millifera and Bombus ignitus variables, the response value of both species was high in 10 out of 20 types. The result of this study is expected to provide basic information for improving the pollination services in the Korean urban area and to be utilized as the basic materials for the future urban planning.
