随着城市化的快速发展,不透水地表面积不断递增,原始的河流、植被等自然生态面积骤减。不合理的规划建设破坏了场地原有的自然水文循环,降低了城市对暴雨水的处理能力、净化能力和储蓄能力,从而致使城市内涝加剧、水体污染和水资源缺乏等城市水问题频发。

With the rapid expansion of urbanization, the area of water-proofing surface keeps increasing while the area of natural ecologies such as primordial rivers and vegetation is decreasing dramatically. Improper urban planning and construction destroyed the primordial hydrological cycle of an area, further weakening abilities of a city to withstand, purify and reserve rainstorm. As a consequence, not only does the waterlogging phenomenon become severe but also lead to the frequent occurrence of problems such as water pollution and water shortage.

基于城市水问题背景下,我国提出了海绵城市建设的目标,要求将生态环境与雨水处理措施有效结合,充分利用场地内的水体、绿地系统等自然空间对雨水进行渗透、调蓄、净化,在不破坏场地原有生态水文特征情况下改善城市内涝、水污染、水资源缺乏等问题,优化城市生态水环境。

Considering serious urban water conditions, Chinese government put forward a mission to establish “sponge cities”, which urges a effective combination of biological environment and treatments of rainwater so that local natural spaces including body of water as well as green space system can be exploited to foster the permeation, regulation and storage and purification of rainwater. Therefore, waterlogging, pollution and shortage issues within a city can be neutralized without damaging primordial biological hydrological characteristics, contributing to an optimized water eco-environment.

本研究基于海绵城市背景下对城市绿地系统的规划响应提出规划策略,并以南充市为例进行具体调查和规划分析,研究表明海绵城市背景下城市绿地系统规划的作用与必要性。研究情况如下:
From such a standpoint, this research provides planning strategies responding to the call of sponge cities and further conducts empirical investigation and analysis taking Nanchong city as an example. The results indicate that it is fundamental and imperative to organize urban green space system under sponge cities social setting. Research details include:

(1)总结国内外海绵城市研究进展及实践,对比国外先进的雨洪管理理念、技术措施及规范等,进一步对对我国海绵城市概念进行梳理,探究了我国海绵城市建设基本原则和途径、技术分类。

(1) Summarize the conception of Chinese sponge cities through reviewing the progress and implementation of both domestic and international research and comparing international advanced stormwater management idea, techniques and regulations. Explore fundamental principles, methods and technical classification of establishing sponge cities.

(2)针对南充市调查现状存在的问题和不足,基于南充市的整体规划,以海绵城市建设为背景,提出对南充市排水情况、水污染情况、内涝情况、绿地情况、主城区景观格局变化情况的响应的规划分析。

(2) Based on social setting to build up sponge cities and existing integrated planning of Nanchong city, we propose analysis and strategies for Nanchong city of water drain-off, pollution, waterlogging, green space and urban landscape pattern in order to respond to current issues and weaknesses of Nanchong city.
