干旱区城市雨水花园建设探析

Discussion on the construction of rainwater garden in cities in arid regions

为了使干旱区雨水花园的设计更加科学,有必要针对干旱气候特征深入探讨雨水花园的植物选择及内部构造。基于生态学原理,讨论了干旱区城市雨水花园建设中植物的选择原则及合理配置;设计了内部构造中有关覆盖层、种植层、人工填料层的物质选用和深度;介绍了雨水花园建设的面积计算及后期的维护管理。旨在建设能够适应干旱气候,同时也能有效处理雨水径流的雨水花园系统。

In order to make the design of the rainwater garden more scientific in the arid area,it is necessary to discuss the plant selection and internal structure of the rainwater garden in detail according to the characteristics of the arid climate.Based on ecological principles,the selection principles and reasonable configuration of plants in the construction of rainwater garden in arid areas were discussed.The material selection and thickness of the covering layer,planting layer and artificial filler layer in the internal structure were designed.The area calculation of rainwater garden construction and subsequent maintenance management were introduced.The aim is to build a rainwater garden system that can adapt to arid climates and can effectively handle rainwater runoff.
