基于海绵城市理论的泸州市道路景观优化策略探究

Research on Luzhou Road Landscape Optimizing Strategy Based on Sponge City Theory

随着城市化进程不断加快,不透水地表日益增加,雨水无法遵循自然规律渗入以补给地下水,短时间内排走,造成大部分城市出现"不雨则旱、雨则涝"尴尬窘境,城市雨洪问题已经变成当下我们需要面对的一个巨大挑战。本文以泸州地区道路景观为研究对象,通过对实地进行调研,找出现有道路景观在排水方面的问题所在,以"问题导向"为基础提出泸州市道路景观在海绵城市指导下的开发改造模式,寻找海绵城市理论及技术在道路景观中运用的切入点,旨在为城市健康发展提供一些思路。

With the acceleration of urbanization and the increasing of impervious surfaces,rainwater can no longer infiltrate into groundwater to recharge it as before.A large number of drainage in a short period of time leads to an embarrassing situation of"drought without rain while flooding with rain"in many cities.Urban rains and floods have become a big challenge at present.This paper takes the road landscape in Luzhou as the research object,finds out the existing problems in drainage of road landscape through field investigate,and puts forward the development and transformation mode of road landscape in Luzhou under the guidance of sponge city based on"problem-oriented",so as to seek for the theory and technology of sponge city to be transported in road landscape.The purpose of this paper is also to provide some ideas for the healthy development of cities.
