RETRACTED ARTICLE: Environmental change of rainfall erosivity based on GIS system and architectural design of sponge city

Abstract

With the continuous development of society and the continuous improvement of scientific and technological level, it has greatly promoted the development of many fields. Especially civil engineering, civil engineering plays an important role in the development of China. Civil engineering survey is an indispensable part of civil engineering work. The application of GIS system technology in engineering survey helps to improve the accuracy and efficiency of survey, ensure the orderly development of the project, and improve the construction quality. However, rainfall erosivity reflects the potential ability of rainfall to cause soil erosion. Many scientists use R value of rainfall erosion rate to calculate soil erosion coefficient and draw curve equation. Therefore, it is an important guideline to study the spatial and temporal distribution characteristics of R value, establish simple regression function, quantitative prediction of soil and water loss, and soil and water conservation plan. With the continuous changes of economy and society, the global environment is also changing, which inevitably affects human beings. With the accelerating process of new urbanization, urban planning and architectural design are also deepening. On the one hand, it is necessary to improve the urban living environment and seriously implement the construction of sponge city. On the other hand, the green roof design of urban rainwater drainage and storage must be coordinated with it. The sustainable development of economy and society promotes the strong rise of construction industry. Architectural design is an important part of construction engineering, which can represent the construction standard of construction engineering. Based on the research of GIS system and rainfall erosivity environment change, this paper applies it to the architectural design of sponge City, and then promotes the vigorous development of urban construction.
