Abstract
The process of urbanization is a complex and dynamic process,and exploring the spatiotemporal changes in precipitation in areas with significant urbanization is of great significance for future flood control and water resource management in cities.This study analyzed the spatiotemporal evolution characteristics of urbanization process in Shenzhen based on remote sensing image data,and analyzed the spatiotemporal evolution characteristics of annual precipitation based on daily precipitation data.Finally,the impact of urbanization development on the precipitation characteristics of the city was studied through comparative analysis between urban and suburban areas.The results indicate that the number of annual precipitation days in the city has shown a significant downward trend,and urbanization has an enhancing effect on precipitation indicators in urban areas.The research results can provide a basis for local flood planning and urban development.关键词
