| Summary: | 碩士 === 東海大學 === 景觀學系 === 101 === The process of real estate development, a highly-polluted industry, will be confronted with the nature unavoidably. Blowing dusts and gas emission by the construction vehicles and machines and tools during the process of urban building construction give rise to lots of dusts and aerosols in the air that cause serious air pollution, while poor environment for the surroundings of the construction base further makes construction fences look visually dull and dirty and lack affinity. The design of green fences will thus turn construction fences which are cold with blowing dusts into beautiful green landscape. On-site survey and evaluation method was used in this research to conduct on-site observation, record, and survey and analysis in evaluating plant coverage ratio, coverage homogeneity, growth activity, appreciation, and maintenance management of green fences installed on three construction sites located in Taichung City, integrating the appropriate module and technology for green construction fence. Three kinds of plants grown on green construction fences of Hsiang Chen Construction have shown poor growth and wilting. There are some problems about basic structure, water supply system and maintenance by Hsiang Chen for the green construction fences. In water supply method adopted by Lee Ming Construction, water supply at the front end differs from that at the rear end. As the excessive water at the front end caused the plants to die, insufficient water pressure and water impurities thus gave rise to water supply shortage at the rear end that clogged the drain holes. Despite the careful maintenance for green fences by Lien Jade Construction, water-storage groove in the bottom side should be an attention issue for regularly cleaning the lost medium to prevent clogged groove causing water overflow that gives rise to the factor which will ruin the quality. The suggestion is put forward that light screen is installed on the top of construction fence, and seedlings of the shelf should be closely connected with the gap to be not so large, and seedlings arranged side by side for a better growth. Hanging plants that are low maintenance, such as Sprengeri fern, Boston fern and Bird's-nest fern, will be the selection priority, especially drought-enduring plants. Most of water supply systems with no purifier installed will easily cause clogged opening that will lead to water overflow that gives rise to serious pollution and waste of water resource. Life cycle for plants grown in vessel modules is shorter, and lifecycle for plants on iron weld module is, on the contrary, longer. As being uneven in the appreciation of construction fence, manufacturers which value corporate image may pay more attention to maintenance that makes the green fence show more appreciation; no maintenance at some construction sites will result in the environmentally dirty source. After plants wilt or die, most of modules left in the site will turn into secondary pollutants. The design, construction and maintenance management of green construction fence should be carried out by experts and professionals; the designer and maintenance manager should be ones who have expertise in plants, or plentiful manpower and expenditure may not lead to greening and landscaping effects but urban uglification on the contrary.
