- Title:
- Growth Rate of Stormwater Intensity and Effect of Urbanization in Some Cities of China
- 摘要:
- 研究城市化效应对暴雨强度的影响,对改进城市排水管渠系统的设计有重大意义。为此,利用北京、赣州、杭州、南宁、深圳、武汉、西安共7个城市的年最大值降雨数据,编制各年代的暴雨强度公式,分析各城市暴雨强度的年代际变化,探讨城市化程度及气候变化对城市降雨的影响。另外,根据全国126 个城市在20世纪中后期以及21世纪发布的新旧暴雨强度公式,计算各重现期下城市暴雨强度的增长率,分析变化趋势的空间分布,发现暴雨强度呈增长趋势的城市大部分位于沿海地区或属于发达地区,部分地区有必要对暴雨强度公式进行更新以应对如今的降雨情况。
- Abstract:
- To improve the design of urban drainage system, it is of great significance to investigate the effect of urbanization on stormwater intensity. Based on the annual maximum precipitation data of seven cities (Beijing, Ganzhou, Hangzhou, Nanning, Shenzhen, Wuhan and Xi’an), the formula of stormwater intensity in each decade was compiled to analyze the interdecadal variation trend of stormwater intensity in each city, and the effects of urbanization degree and climate change on urban precipitation were explored. In addition, according to the old and new stormwater intensity formulas published by 126 cities in the middle and late 20th century and the 21st century, the growth rate of urban stormwater intensity in each return period was calculated, and the spatial distribution of the trend was analyzed. It was found that most of the cities with increasing stormwater intensities were located in coastal or developed areas. It is necessary to update the stormwater intensity formula in some areas to cope with the current precipitation situation.
