福寿沟建设理念对于现代海绵城市建设的启示

近年来,传统灰色基础设施带来的"城市病"越发凸显。突发罕见的暴雨所导致的城市内涝给我国多地造成了重大的人员伤亡和财产损失。海绵城市建设是防治城市内涝的主要技术措施之一,其核心理念是将排水功能归还于自然。福寿沟是我国宋代时期建成的地下排水系统,是世界上早期最杰出的排水系统之一。福寿沟通过利用自然本身进行雨洪调蓄,其精妙的设计思想、工作原理对于现代海绵城市建设具有极强的指导意义。从国内外海绵城市的研究现状入手,充分挖掘海绵城市的深层含义,探究海绵城市构建的哲学思想,再引入福寿沟的建设理念,通过剖析福寿沟结构、工作原理、建设思想,结合《海绵城市建设技术指南》中海绵城市建设的五大基本原则,最终得出福寿沟建设理念对于现代海绵城市建设的三大启示,即规划引领,因地制宜,核心是"天人合一";生态优先,统筹建设,关键是"以人为本";根除病根,城镇转型,方法是"绿色先行"。

Revelation of Fushougou ditch's conception for the construction of modern sponge city

In recent years,the"urban disease" brought by the traditional gray infrastructure has become more prominent. The urban waterlogging caused by rare rainstorm has caused significant casualties and property losses in many areas of China. Sponge city is one of the main technical measures to prevention and control of urban waterlogging and its core idea is to return the drain-age function to nature. The underground drainage system of Fushougou ditch was built in the Song Dynasty, it is one of the most outstanding drainage system at that time. Fushougou ditch stores and regulates storm water according to the law of nature. Its ex-quisite design thought and working principle has strong guidance significance for the construction of modern sponge city. Based on the research status at home and abroad, this paper fully extract the deep meaning of sponge city, explores the philosophic think-ing of sponge city′s construction, then according to the conception of Fushougou ditch′s construction, through the analysis of the Fushougou ditch′s structure, working principle and construction ideology, combining with the five basic principles of the Sponge City Development Technical Guide, finally, we give out enlightenment for the construction of modern sponge city, i. e, guided by plan and adapting to local conditions with integration of nature and human as the core;ecology as the priority, coordinated con-struction, human-oriented guideline;eliminating the root cause and implementing transformation of city and town with green as the priority .
