中文摘要 | 薄層綠化屋頂為減輕載重,多採用淺薄介質,卻因而提高介質溫度,造成植物生長的高溫逆境。故本研究目的是探討台灣地區薄層綠化屋頂介質深度對於介質溫度變動之影響。採用花盆模擬薄層綠化屋頂結構,以5 cm、10 cm、15 cm三種介質深度作為本研究之處理,以熱耦線測量介質溫度。研究發現在日間,深度15 cm的介質溫度顯著低於10及5 cm的介質;深度15 cm介質的蓄水板水溫亦顯著低於深度10及5 cm介質的水溫。介質溫幅由小而大依序是15、10 及5 cm介質。未來極端氣候日益明顯,建議台灣薄層綠化屋頂的介質宜採用15 cm深度,將可提供較穩定的介質環境供植物生長。 |
英文摘要 | The extensive green roofs usually use thick substrate to reduce the weight load of building. However, the thick substrate causes height temperature stress in substrate. It results in the temperature stress of plant. The purpose of this study is to discuss how the substrate depth influent on substrate temperature on extensive green roof. The flowerpots are used to simulate the extensive green roof. Three substrate depth (5, 10 and 15 cm) are regard as treatment of this study. The temperature is measured by the thermocouple. It reveals that on daytime, the substrate temperature of 15 cm is significant lower than that of 10 and 5 cm. As well as the water temperature of 15 cm in water retention plate is also significant lower than that of other two treatments. The sequence of the temperature range from small to large is 15 cm, 10 cm and 5 cm depth of substrate. In the future, the extreme temperature will happen frequently, it is proposed that using 15 cm depth substrate on the extensive green roof to maintain a stable habitat for plant growth in Taiwan. |
