基于地理国情普查数据的郑州市海绵城市建设途径研究
|
摘要
海绵城市建设是城市建设的重要工作。近年来,郑州市积极推进海绵城市建设,为了从区域层面明确郑州市区各海绵体建设特征,定量的、科学的指导海绵城市建设途径,采用地理国情普查数据,借助地理信息系统、excel软件平台定量分析郑州市区海绵城市建设进程。2015年,郑州市区不透水面积占比为53.2%,综合雨量径流系数为0.54,年径流总量控制率为46%,金水区不透水面积占比最高,其次是管城区、中原区。到2030年,郑州市区80%以上面积达到海绵城市建设目标需综合雨水径流系数达到0.35左右,年径流总量控制率达到65%左右。结合相关政策法规,设定了特定的情景模拟,可实现郑州市区海绵城市建设目标。
Sponge city construction is an important work of urban construction. In recent years,Zhengzhou promotes the sponge city construction actively. In order to clarify the characteristics of Zhengzhou urban construction corpus from the regional level and guide the sponge city construction quantitatively.Construction process in Zhengzhou sponge city was analyzed with the geographic information system and the software platform of Excel using census data of geographical conditions in 2015. Zhengzhou urban impervious area accounted for 53.2%,comprehensive rainfall runoff coefficient was 0.54,and the annual runoff control rate was 46%. The impervious area in Jinshui district accounted for the highest,followed by Guangcheng district,Zhongyuan district. By 2030,the comprehensive runoff coefficient will reach about 0.35,and the total annual runoff control rate will be about 65% when more than 80% of the urban area in Zhengzhou reaches the goal of building a sponge City. Combined with relevant policies and regulations,specific scenario simulation is set up to achieve the goal of sponge city construction in Zhengzhou City.
