屋顶绿化已经受到政府和市场各方的重视,将成为21世纪城市建设的新景观。目前屋顶绿化的轻型平屋顶绿化意义最大,难度最高。上海市农业科学院生态环境保护科学研究所经过多年试验研究出的一套适用于轻型平屋顶绿化的“屋顶绿化一次成坪技术”,较好地解决了轻型平屋顶绿化的技术难题。该技术建设的屋顶只需铺上3-5厘米的栽培层,再铺上佛甲草苗块,立即成坪,即可交付使用。以后无需浇水、修剪、施肥,也能具有常年景观效应。该技术在上海已有6万平方米以上的应用面积,北京试用基本成功。项目组又从国外引进和国内驯化10多个品种,通过近3年的跟踪考察和研究,从中挑选出适用于屋顶绿化的几个彩色品种,可以改变佛甲草颜色单调、品种单一、冬天绿色不艳以及生态群落弱等缺点。
Green roof has been the government and the market attention of all parties, will become the 21st century city landscape. At present, green roofs of light green roofs have the greatest significance and the highest degree of difficulty. After years of experiments, the Institute of Eco-Environmental Protection, Shanghai Academy of Agricultural Sciences has developed a set of “roof greening once-forming technology” suitable for light-weight flat roof greening, which has solved the technical problems of light green roof construction. The roof of the technology building only spread 3-5 cm of cultivation, and then covered with the Buddha grass seedlings, immediately Ping, you can deliver. After no need to watering, pruning, fertilization, but also can have perennial landscape effects. The technology in Shanghai has more than 60,000 square meters of application area, Beijing trial basic success. The project team also introduced and domesticated more than 10 varieties from abroad. After nearly 3 years of follow-up study and research, several color varieties suitable for roof greenery were selected, which could change the color of Monochoria monotonous, single variety and winter green Not bright and weak ecological community and other shortcomings.
