방위에 따른 벽면녹화식물의 생육 비교†

Abstract

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, <italic>Parthenocissus tricuspidata</italic> was prolific in the north, and <italic>Hedera rhombea</italic>, and <italic>Euonymus radicans cv. Aueonmarinata Rehd</italic> plants were prolific in the south. All three types of plants were prolific in June-July, and the <italic>Parthenocissus tricuspidata</italic> was prolific in grass-growing, and in August, all the walls were 100% covered. <italic>Hedera rhombea</italic> 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. <italic>Euonymus radicans cv. Aueonmarinata Rehd</italic> 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.
