摘　　要：在我国,水资源短缺已经成为制约城市可持续发展的重要因素。节约城市用水,提高园林用水的利用率是我国城市园林发展的必然趋势。保水剂是一种含强亲水性基团并经过适度交联的功能高分子材料,能吸收自身重量几百倍甚至上千倍的水分,且保水保肥能力显著,近年来在城市园林绿化中越来越受到重视。在简要介绍保水剂发展概况的基础上,重点综述了保水剂在城市园林绿化中的应用研究现状,并对保水剂在城市园林绿化应用中存在的问题和发展前景进行了探讨。Water shortage has become an important limitation factor of city sustainable development. Saving urban water and increasing garden water use efficiency is an inevitable trend in China＇s city landscaping development. Water retaining agent （WRA） is a kind of propor crosslinking functional polymer material which contains strong hydrophilic groups. It can absorb water as hundreds times as, or even more than a thousand times as its own weight and has a nice water and nutrient conservation capability. In recent years, WRA has been paid more and more attentions in city landscaping. Based on the introduction of the general situation of WRA, as an emphasis, its research and application status in city landscaping are reviewed. The existing problems and development prospect of WRA in city landscaping applications are also discussed.
