【摘要】：隨著城市快速發(fā)展,人居環(huán)境已成關(guān)注重點,屋頂綠化的出現(xiàn)為城市環(huán)境的改善提供了新思路。酸雨已成為世界三大環(huán)境問題之一,研究通過對酸雨危害和防治方法的綜述,提出應(yīng)增加適宜屋頂綠化的植物和基質(zhì)在酸雨改善作用方面的研究,并指出推廣屋頂綠化是防治酸雨危害的有效措施。 針對現(xiàn)有的不足,選取適應(yīng)屋頂綠化的植物和基質(zhì),通過模擬酸雨淋溶實驗,提出陶粒和馬尼拉的植物基質(zhì)組合改善酸雨pH效果較好。 通過調(diào)查長沙市屋頂綠化發(fā)展現(xiàn)狀,深入探討屋頂綠化生態(tài)服務(wù)功能、植物景觀以及下界面等因素,對比國內(nèi)外案例,結(jié)合其發(fā)展經(jīng)驗,提出適合長沙的屋頂綠化推廣措施。 研究實例部分以調(diào)查結(jié)論和實驗數(shù)據(jù)為指導(dǎo),結(jié)合場地特殊性,經(jīng)植物配置、界面設(shè)計和細(xì)節(jié)設(shè)計等手法,將場地酸雨防治、休閑、教育三大功能有機(jī)糅合,為屋頂綠化設(shè)計提供新的方向。 根據(jù)調(diào)查、研究和實踐提出挖掘屋頂綠化在PM2.5、重金屬、霧霾等環(huán)境污染方面的積極作用,融入雨水收集和利用是屋頂綠化生態(tài)服務(wù)功能的拓展和延伸。
[Abstract]:With the rapid development of cities, human settlements have become the focus of attention. The emergence of roof greening has provided a new idea for the improvement of urban environment. Acid rain has become one of the three major environmental problems in the world. Based on the review of acid rain harm and control methods, it is suggested that the improvement of acid rain by plants and substrates suitable for roof greening should be increased. It is pointed out that popularizing roof greening is an effective measure to prevent and cure the harm of acid rain. In view of the existing deficiency, the plants and substrates adapted to roof greening were selected, and through simulated acid rain leaching experiments, it was suggested that the combination of ceramsite and Manila plant substrates could improve the pH of acid rain better. Through investigating the present situation of roof greening development in Changsha City, this paper probes into the ecological service function, plant landscape and lower interface of roof greening, and compares the domestic and foreign cases, and combines its development experience. The promotion measures of roof greening suitable for Changsha are put forward. The research example part is guided by the investigation conclusion and experimental data, combined with the site particularity, through plant configuration, interface design and detail design, the site acid rain prevention and control, leisure, education three major functions are organically combined. Provide a new direction for roof greening design. According to the investigation, research and practice, the active role of digging roof greening in PM2.5, heavy metal, haze and other environmental pollution was put forward. The integration of Rain Water collection and utilization is the expansion and extension of the ecological service function of roof greening.
