Analysis of Impervious Area Change in Shijiazhuang Urban Area

Abstract

In recent years, with the rapid development of the economy, China has attached more importance to the construction and development of cities. With the rapid increase in the number of cities, people have higher and higher requirements for modern facilities in cities. However, in the process of urbanization, we need to consider not only the facilities and planning of the city, but also more importantly, to achieve a harmonious coexistence between the city and the natural environment. At present, because the vast majority of urban ground area is used for construction, the misuse of cement and concrete has led to serious heat island effect and impermeable area problems. These two phenomena lead to urban water shortage and increasing incidence of flood disasters. This paper takes Shijiazhuang City as an example to analyze the change of impervious area and its impact on urban vegetation and water cycle through a series of data in order to promote the perfection of urbanization. It also reflects on the existing problems and defects, from the aspects of technology, material, production and life, then put forward relevant suggestions and ideas, hoping to provide certain enlightenment to solve the impervious area problems.
