【摘要】：屋顶绿化是由传统地面绿化上升为空间立体绿化的综合性现代绿化新技术,它不仅可以更多的争取绿化空间,缓解用地矛盾,还可以改善城市生态环境、调节小气候、保温隔热、美化环境、陶冶人们情操等多重功能。兰州市作为甘肃省的省会城市,其生态环境脆弱、城市绿化用地紧张,面对当前城市绿化用地难以扩增的现实问题,实施屋顶绿化可有效增加绿化空间面积。本文以兰州市生态环境状况为现实依据,针对兰州市目前屋顶绿化现状,对屋顶绿化草坪种植基质、屋顶绿化种植植物的选择以及屋顶绿化施工设计新技术等内容进行了研究,并得出以下主要结论：(1)在不同处理的基质中,综合各基质中供试植物草坪草的生长状况可知处理3基质(基质配比为：炉渣、有机污泥堆肥40%；蘑菇废料、锯末、秸秆30%；壤土22%；保水剂3%；缓释肥5%；基质厚度为15cm)中草坪草生长表现最好,耗水量小且生长旺盛,基质层重量相对较轻,最适于干旱半干旱区屋顶绿化建植中草坪栽培基质的选用,且起到了废弃物转化利用的功效；(2)植物选择方面,从兰州市常用的园林绿化植物中选用备选植物33种,通过实地调查、大田观测、专家咨询、层次分析法等方法,综合选择出适宜于兰州市屋顶绿化种植的植物有：天人菊、黑心菊、蜀葵、红景天等10种综合性状表现最优的植物,及小丽花、鸡冠花、矮牵牛、八宝景天、草地早熟禾等20种综合性状表现次优的屋顶绿化植物,这些植物均可在兰州地区屋顶绿化中推广应用；(3)施工设计方面,结合兰州市屋顶绿化施工设计实例,分别对屋顶绿化施工技术中常见的防水、排水、屋顶承重、植物种植、景观设计等问题进行全面分析,并首次引入了屋顶绿化新技术——智能终端控制灌溉系统,以期为西北地区屋顶绿化技术探索研究开辟新模式。
[Abstract]:Roof greening is a new comprehensive modern greening technology from traditional ground greening to spatial stereoscopic greening. It can not only strive for more greening space, alleviate the contradiction of land use, but also improve the urban ecological environment and adjust the microclimate. Thermal insulation, beautification of the environment, edify people sentiment and other multiple functions. As the capital city of Gansu Province, Lanzhou has a fragile ecological environment and a shortage of urban greening land. In the face of the current problem that the urban greening land is difficult to expand, the implementation of roof greening can effectively increase the green space area. Based on the ecological environment of Lanzhou city and the present situation of roof greening in Lanzhou, this paper studies the planting matrix of roof greening lawn, the selection of planting plants for roof greening, and the new technology of roof greening construction design. The main conclusions are as follows: (1) according to the growth status of turfgrass in different substrates, the ratio of three substrates is as follows: cinder, organic sludge compost 40%, mushroom waste, sawdust, straw 30%; Loam 22m; water retaining agent 3; slow-release fertilizer 5; substrate thickness 15cm) the turf grass has the best growth performance, low water consumption and strong growth, and relatively light substrate weight, which is the most suitable for the selection of turf cultivation substrate in roof greening in arid and semi-arid areas. And played the role of waste conversion and utilization; (2) Plant selection, from the common garden plants in Lanzhou, select 33 alternative plants, through field investigation, field observation, expert consultation, analytic hierarchy process and other methods, The plants that are suitable for planting on the roof of Lanzhou City are: Tianren chrysanthemum, black heart chrysanthemum, hollyhock, Rhodiola, etc., which have the best comprehensive characters, as well as the small lily flower, the cockscomb flower, the petunia, the eight treasure Jingtian, and so on. There are 20 kinds of suboptimal roof greening plants, such as bluegrass, which can be popularized and applied in the roof greening of Lanzhou area. (3) in construction design, combined with the example of roof greening design in Lanzhou City, The common problems of waterproofing, drainage, roof bearing, plant planting and landscape design in the construction technology of roof greening are analyzed respectively, and the new technology of roof greening, intelligent terminal controlled irrigation system, is introduced for the first time. In order to open up a new model for the exploration and research of roof greening technology in Northwest China.
