节水抗旱技术在城市园林绿化中的开发与应用——以北方城市沈阳为例

Development and Application of Water-saving Technology in Urban Landscaping:A Case Study of Shenyang as a North City

随着城市园林绿地面积的增加,城市水资源出现短缺,再加上极端气候的影响,节水抗旱技术的开发和应用是城市园林发展的必然趋势。文章讨论有机覆盖基质技术、节水灌溉技术、保水剂、抑制蒸腾剂4种节水抗旱技术的应用,以期为以后城市绿化节水抗旱提供对策。

With the increase of urban landscapes and green spaces,the shortage of water resources in cities,and the impact of extreme weather,the development and application of water-saving and drought-resistance technology is the inevitable trend for the development of urban landscape. This paper discussed four kinds of water-saving technology,including the organic mulch substrate technology,water-saving irrigation technology,water retaining agent,transpiration inhibiting agent,which are aimed to provide the countermeasures of water-saving and drought resistance oriented urban landscaping.
