【摘要】：隨著我國經(jīng)濟(jì)的迅猛發(fā)展、城市化進(jìn)程的加快,城市人口越來越密集,道路、建筑占據(jù)大量的城市空間,城市的可用土地越來越少,城市綠化的壓力越來越大。園林綠化發(fā)展與用地的矛盾是當(dāng)前城市園林綠化發(fā)展的重點(diǎn)問題,綠化覆蓋率和人均綠地指標(biāo)在城市中心地區(qū)嚴(yán)重不足。為解決惡劣的環(huán)境問題,促進(jìn)生態(tài)園林建設(shè),在保證現(xiàn)有平面綠化的基礎(chǔ)上,綠化還需要向垂直綠化、空中花園等多種方式發(fā)展。目前,國內(nèi)屋頂綠化上還存在各方面的問題,如:缺乏對本土氣候和文化風(fēng)情的考慮、沒有明確的設(shè)計(jì)定位、養(yǎng)護(hù)困難且成本高等。因此急需一種簡便高效的屋頂綠化方式,以解決需求巨大和發(fā)展緩慢之間的矛盾。本文第一步分析了國內(nèi)外屋頂綠化的發(fā)展歷史和趨勢。第二步通過對傳統(tǒng)屋頂綠化景觀類型及存在的問題的分析,對屋頂綠化的人群行為特征與屋頂綠化設(shè)計(jì)的聯(lián)系、景觀要素進(jìn)行分析與探索。然后通過國內(nèi)外不同區(qū)域案例的分析,并結(jié)合低維護(hù)簡易型屋頂綠化的特點(diǎn),對不同區(qū)域的低維護(hù)簡易型屋頂綠化設(shè)計(jì)進(jìn)行探索。第三步,主要從荷載、灌溉、防水、植物選擇、圍護(hù)等方面論述低維護(hù)簡易型屋頂綠化的工程技術(shù),并對圍護(hù)結(jié)構(gòu)進(jìn)行了試驗(yàn),并得出其圍護(hù)結(jié)構(gòu)具有可行性。第四步,對低維護(hù)簡易型屋頂綠化主要使用植物華南鋪地錦竹草的適用基質(zhì)進(jìn)行試驗(yàn),以到達(dá)提高經(jīng)濟(jì)效益的目的,也是推廣低維護(hù)簡易型屋頂綠化技術(shù)的重要因素之一,得出當(dāng)田園土、椰糠、泥炭土比例為4:3:3時(shí)最適合華南鋪地錦竹草生長。最后,基于以上研究,總結(jié)出低維護(hù)簡易型屋頂綠化景觀形式具有投入和管理成本低,重量輕、易推廣,經(jīng)濟(jì)實(shí)用等特點(diǎn),并對低維護(hù)簡易型屋頂綠化景觀形式與工程技術(shù)的適用、觀賞和推廣價(jià)值做嘗試性探討。
[Abstract]:With the rapid development of China's economy and the acceleration of urbanization, the urban population is becoming more and more dense, roads and buildings occupy a large amount of urban space, and the available land in cities is becoming less and less. The pressure of urban greening is increasing. The contradiction between the development of landscaping and land use is the key problem in the development of urban landscaping. The greening coverage rate and the per capita green space index are seriously insufficient in the urban center area. In order to solve the bad environmental problems, To promote the construction of ecological gardens, on the basis of ensuring the existing planar greening, greening still needs to be developed to vertical greening, aerial gardens, and so on. At present, there are still various problems in domestic roof greening. For example, lack of consideration of local climate and cultural customs, lack of clear design orientation, difficult maintenance and high cost, etc. Therefore, a simple and efficient method of roof greening is urgently needed. In order to solve the contradiction between huge demand and slow development, the first step of this paper is to analyze the development history and trend of roof greening at home and abroad. The second step is to analyze the traditional landscape types and existing problems of roof greening. This paper analyzes and explores the relationship between the crowd behavior characteristics of roof greening and the design of roof greening, analyzes and explores the landscape elements. Then through the analysis of different regional cases at home and abroad, it combines the characteristics of low maintenance simple roof greening. This paper probes into the design of low maintenance and simple roof greening in different areas. The third step mainly discusses the engineering technology of low maintenance simple roof greening from the aspects of load, irrigation, waterproofing, plant selection, enclosure, etc. The experiment on the enclosure structure was carried out, and the feasibility of the enclosure structure was obtained. 4th steps were obtained. The suitable substrate for the low maintenance and simple roof greening was tested, which mainly used the plant South China to improve the economic benefit. It is also one of the important factors in popularizing low-maintenance and easy-type roof greening technology. When the ratio of pastoral soil, coconut chaff and peat soil is 4: 3: 3, it is most suitable for the growth of bamboo and bamboo grass in South China. Finally, based on the above research, It is concluded that the low maintenance simple roof greening landscape form has the characteristics of low input and management cost, light weight, easy to be popularized, economical and practical, and is suitable for the low maintenance simple roof greening landscape form and engineering technology. To explore the value of appreciation and promotion.
