我国是世界公认的13个淡水资源最贫乏的国家之一，而北方又是我国缺水严重的地区，且随着我国城市化发展进程的加快，人均拥有量将更加减少。为此，在我国北方推进节水节能型园林建设很有必要。推进节水节能型园林建设，须淘汰现有的、落后的灌溉方式，采用滴灌、渗灌等先进灌溉方式。且要大力发展集雨工程建设，将集雨工程建设作为现代园林建设的一项标准，需有专项资金扶持。通过对我国城市园林绿地用水来源和节水技术进行分析，列举我国城市园林节水的途径，为我国节水型园林绿地建设提供指导。%Water scarcity is significant in the northern China, which requires us to vigorously promote water-saving garden construction. Advanced water-saving facilities such as drip irrigation, subsurface irrigation and other equipment should be used to promote various water-saving technologies, eliminate the outdated irrigation, vigorous develop rainwater-garden. Through the analysis of water problems of landscaping, it explored the ways of urban garden rainwater utilization, described the practical significance of the construction of water-saving landscaping. This article analyzed water sources and water saving technologies of city landscape, listed several ways of water-saving of city garden, and would provide a significant guidance to domestic water-saving landscape construction.
