摘要
从应用乡土植物、耐旱植物,灌溉方式,再生水应用,雨水收集和利用几方面对北京市园林绿地节水情况进行调查。结果表明,很多绿地中应用耐旱植物,应用喷灌、滴灌等节水灌溉方式;应用雨水收集系统、下凹绿地、透水材料铺装等收集雨水和增加入渗量;有条件的绿地应用再生水等各种措施减少对自来水的消耗。但节水型园林绿地建设存在一些问题,设计中仍未采用节水灌溉方式,未考虑雨水收集利用;地面铺装过大并采用不透水砖,造成雨水的浪费等;使用再生水等的绿地所占比例少;养护工人在养护浇水过程中存在水资源浪费现象。针对存在的问题,提出建议,以利于加快节水型园林绿地的建设。
The investigations on the present status of watevsaving landscape gardens were carried out in Beijing, which included the application of native plants and drought resistance plants, irrigation mode, the application of reclaimed water and the collection and using of rainwater. The results indicated that drought resistance plants were cultivated in many landscape gardens, the water-saving modes including sprinkler irrigation and drop irrigation were also applied, all of rainwater collection system, low-lying landscape gardens and the spread of water-penetrating material were adopted to collect rainwater and increase the amount, additionally, reclaimed water was also used in some landscape gardens. But some problems were found in development of water-saving landscape gardens, for instance, there were no water-saving irrigation and rainwater collection system, the bricks spread on the road could not permeate rainwater, landscape gardens used reclaimed water were few, water waste phenomenon existed in irrigating landscape gardens, and so on. Aiming at the problems, some relevant suggestions were put forward in this paper to quicken the development of water-saving landscape garden.
