生态水文学视角下的山地海绵城市规划方法研究——以重庆都市区为例

摘要

Facing a conflict between the frequently occurring disasters of urban water-logging and a rapid development of new urbanization & ecological civilization construction,the urgency and importance of research on Sponge City is concerned,especially for solving the problems caused by rainstorm and urban flood,and rebuilding urban hydrology system.As one of the main regions,the constraints and difficulties in construction of sponge city in mountain areas are characterized by the features including natural topography,climate and hydrology,urban construction,and etc.By selecting Chongqing downtown area as a case study,this paper,based on systematic analysis on mountainous hydrology features,introduced a theoretical and technical coupling of eco-hydrology system and sponge city planning.It also put forward to general ways of Chongqing sponge city planning,including the methods of target,eco-pattern,stormwater management unit,site plan.This was done with the aim of making sponge city construction methods practicable and fulfilling the value of theoretical innovation and practical guidance of mountainous sponge city.%海绵城市是我国新型城镇化和生态文明建设的重要内容,在城市内涝灾害频发的背景下,具有缓解雨洪灾害和水资源短缺问题、构建城市水文安全体系的重要意义.山地作为海绵城市建设的主体区域之一,其海绵城市建设受到自然地形、气象水文和城市建设等多方面因素的制约.本文以重庆都市区为研究对象,在系统梳理山地水文过程特征的基础上,将生态水文体系与海绵城市规划两者间的理论性和技术性耦合,提出重庆都市区海绵城市规划建设的一般途径,从建设目标、生态空间、雨水单元、场地规划等角度制定规划管控措施,落实海绵城市建设要点,实现山地海绵城市规划的理论创新和实践指导价值.
