宜兴市某警训基地海绵城市设计方案探讨

Discussion on Sponge City Design Scheme of a Police Training Base in Yixing

摘要:

纵观当下中国的发展情况，国内的城镇化发展速度在持续提升，而在此背景下，城市建设工作也在有条不紊地进行，其间出现了硬质铺装、开发强度高等一系列问题，尤其是在道路、屋面以及地面等设施建设过程中出现下垫面过度硬化这样的情况，使得城市先前的水文特征以及自然生态本底受到严重影响。基于此，海绵城市的理念应运而生。海绵城市，是新一代城市雨洪管理概念，是指城市能够像海绵一样，在适应环境变化和应对雨水带来的自然灾害等方面具有良好的弹性，能对雨水径流进行科学管控。宜兴市作为江苏省首批省级海绵城市试点城市，积极推进海绵城市建设。以宜兴市某警训基地作为海绵城市研究分析对象，主要从目标指标、汇水分区划分、海绵设施布局、调蓄容积计算等方面进行分析探讨，以期为类似场区的海绵城市设计提供思路和借鉴。

Abstract:

Looking at the current development situation in China, it can be understood that the development speed of urbanization in China is continuously increasing. Under this background, the urban construction work is also proceeding in an orderly manner. During this process, a series of problems emerge, such as hard paving and high development intensity. Especially during the construction of facilities such as roads, roofs and ground surfaces, there is a situation where the underlying surface is overly hardened, which has severely affected the previous hydrological characteristics and natural ecological background of a city. Therefore, the concept of a sponge city is born. A sponge city is a new generation of urban rainwater and flood management concept, which means that the city can function like a sponge to have the good resilience in adapting to environmental changes and responding to natural disasters caused by rainwater, thereby scientifically managing and controlling the rainwater runoff. Yixing City, as the first batch of pilot provincial sponge cities in Jiangsu Province, actively promotes the construction of sponge cities. Taking a police training base in Yixing City as the object of sponge city research and analysis, the analysis and discussion are conducted mainly from the aspects of target index, catchment zoning, sponge facility layout and storage volume calculation in order to provide the ideas and methods for sponge city design in similar fields.
