【摘要】 随着我国社会经济的持续快速发展、科学技术的大幅度提高和城市化步伐的不断加快,人们对人居环境提出了新的更高的要求,寻求建立安全、健康、舒适的城市环境已成为绝大多数城市居民的共识。城市的绿化环境质量已成为衡量一个城市发展状况的重要指标。城市生态系统中具有自净能力的城市绿地,在维护城市生态平衡、美化城市景观、提高城市品位、改善城市生态环境等多方面发挥着十分重要的作用,这是城市生态系统中其他基础设施所无法替代的。城市绿地被视为维系城市可持续发展的重要因素之一,它绝对不是可有可无的景观装饰物,也不是仅供满足人们休憩、娱乐、活动所需要的游憩场所,而是维护城市居民生存所必需的物质环境空间。然而,随着国民经济的发展和公民环境意识的提高,社会发展城市化和城市建设园林化的趋势日益明显,用于城市绿地灌溉用水量也在逐年增加,导致城市绿地养护成本越来越高。植物存活和生长离不开水,而我国许多地区的多次干旱、频繁的沙尘暴现象、严重的沙漠化、供水失调和地下水位下降等事实,已经尖锐地促使全世界来关注缺水问题。就在人类生存用水日益紧缺的情况下,城市绿地节水灌溉技术在园林中的应用得到重新的认识。目前我国园林用水管理中再生水的利用技术研究较为落后,普遍以自来水或地下水为主要水源,园林用水水资源利用率低,节水体系构建不完善,水资源浪费现象非常严重,加剧了城市用水的紧张程度。因此,研究城市绿地节水灌溉设计将进一步改善生态环境,可有效提高灌溉用水的利用率和利用效率,为城市绿地灌溉达到真正意义上的节水具有现实意义。本文将城市绿地灌溉技术作为切入点,运用SWOT分析法对目前城市绿地节水灌溉项目发展状况,城市绿地节水灌溉自身优势和劣势、发展机遇和面临的威胁进行分析,找出城市绿地灌溉现存的问题。并以此作为突破点,通过对原有技术的改进和新技术的引进对城市绿地节水灌溉设计进行研究,其主要包括灌溉方式的选择、灌溉设备的选择和喷灌景观化设计三个方面的内容。在理论分析与实践相结合的基础上,总结出目前城市绿地节水灌溉的一些技术、管理措施,探索性地归纳出城市绿地节水灌溉设计的原则,以期为今后更好地推广和发展城市绿地节水灌溉做出一点微薄之力。更多还原

【Abstract】 Along with our country social sustained rapid economic development, science and technology greatly improved and accelerating the pace of urbanization, people on the residential environment puts forward the new higher requirements, sought to establish safe, healthy and comfortable urban environment has become most of the city residents consensus. City’s green environmental quality has become the measure of a city development status of important indexes. Urban ecological system has the self-purification urban green space, in maintaining ecological balance, and beautify the city urban landscape, improve the urban grade and aspects of improving urban ecological environment plays very important role, this is of urban ecosystem, other infrastructure is unable to substitute. Urban green space sustaining urban sustainable development is regarded as one of the important factors, it absolutely is not an option, not the landscape decoration only for meet the people have a rest, entertainment, recreation activities need, but maintaining the city residents place necessary for survival to the physical environment space. However, with the development of national economy and the improvement of environmental awareness citizens of urbanization and social development trend of urban construction activities, used for urban greenbelt is more and more obvious in irrigation requirement increasing year by year, lead to more urban greenbelt maintenance cost is high.Plants survival and growth cannot leave the water in China, and many areas of many drought, frequent sandstorms phenomenon, severe desertification, water supply disorders and ground water levels fall facts and so on, has pointedly prompted the world to pay attention to the problem of water shortage. Human survival in case of increasing scarcity of water, water-saving irrigation of urban green space in the Landscape by re-understanding. At present ,our country garden water management in renewable water use technology research is comparatively backward, generally with water or ground water, garden water for main water utilization rate is low, water-saving system construction is not perfect, water resources waste phenomenon is very serious, intensifies the municipal water strain degree. Therefore, the research of urban greenbelt water-saving irrigation optimization design will effectively improve the ecological environment, which can effectively improve the utilization rate of irrigation water and use efficiency of urban greenbelt, the true sense of the irrigation water to be practical.This article will urban greenbelt irrigation technology as a starting point, SWOT analysis on current urban greenbelt development status of water-saving irrigation projects of urban greenbelt water-saving irrigation itself, the advantages and disadvantages, opportunities and the threat to the analysis, find out the existing problems of urban greenbelt irrigation. And so as a breakthrough, through to the original technology improvement and the introduction of new technology of urban greenbelt water-saving irrigation optimization design research, its main including irrigation modes of selection and sprinkler irrigation equipment selection and the design of landscape three aspects. Theoretical analysis and practice in the basis of the combination of the urban greenbelt, summarized the current water-saving irrigation some technology, management measures and exploratory induces urban greenbelt water-saving irrigation optimization design guideline for the future, in order to better promotion and development of urban greenbelt make razor-thin water-saving irrigation of the force.更多还原
