浅议雨水利用的植物配置——以杭州花圃和杭州CBD公园为例

随着我国城市化进程的不断加快,环境问题日益严重,城市稳步快速的推进导致城市的下垫面改变。不透水的硬质表面阻碍雨水入渗地下补给水源,同时增加了地表径流速度,雨水被快速地排入地下管网,造成雨水资源的流失。城市公园的建设对于完善城市水文发展过程具有重要的作用,针对杭州的部分城市公园雨水利用现状与问题,从植被过滤带和生态草沟等方面考虑如何在乔木、灌木,地被的植物配置上更加完善雨水收集利用,从而合理的科学配置能够为人们提供一个整体的生态良性循环环境。

With the rapid development of urbanization in China,the environmental problems are becoming more and more serious.The steady and rapid development of the city leads to the change of the underlying surface.The impervious hard surface prevents the rainwater infiltration and recharging groundwater,and increases the speed of surface runoff.The rainwater is quickly discharged into the underground pipe network,causing the loss of rainwater resources.The construction of urban parks plays an important role in improving the urban hydrological development.In view of the current situation and problems of rainwater utilization in some urban parks in Hangzhou,this paper considers how to improve the rainwater collection and utilization in the allocation of trees,shrubs and ground cover plants from the aspects of vegetative filter strips and bio-swale,so as to make a ecosystems well-cycling for people through reasonable and scientific allocation.
