碩士 === 東海大學 === 景觀學系 === 101 === Recent years, to have green walls in urban Taiwan are in vogue. Together with holding 2010 Taipei International Flora Exposition and the promotion of green landscaping on fences of construction sites; green walls not only help to cut down carbon dioxide emission in urban area, but also make cities greenery. Although there are numerous green walls in Taiwan, the overall landscape varies greatly. With various factors, some plants grow poorly thus green walls have poor overall appearance. The effects of green landscaping are therefore below expectation. The aim of this study is to investigate the factors affecting green wall landscapes with the hope to set guidelines in plant selection, configuration and design of more aesthetics green walls. The research uses landscape preference assessment. Pictures are taken from various green walls throughout Taiwan and rating by preference. In this study seven factors affect the preference of green walls are investigated ― number of plant species, colors and color blocks, plants coverage, integrity of plant types, maintenance and management of plants and color of pots. Moreover, influences of subjective opinions on preference of green walls are investigated. The prediction model about preference of green walls is written as 1.366+.168X2 + .345X5, where X2 equals to number of plant colors and X5 equals to maintenance and management of plants. The model explains total variance equals to 68.4%. All of the investigated factors show a positive linear impact. Moreover, when there are more colors among plants and the more the plants are maintained and managed the rating of preference is higher. Green walls with single color or green plants are monotonous and the rating of preference is lower. The rating enhances when green walls have colorful leaves or flowering plants. Furthermore, the rating also enhances when green walls get more maintenance and management. This study suggests choosing plants apt to branch in order to cover the base of green walls promptly. Moreover, plants need low maintenance are suggested. Even if maintenance is inadequate, plants can still grow well. The study result can be a reference to outdoor green walls and for the enhancement of their ornamental.
