Analysis of the impact of high-density urban design on regional ecological environment and evaluation in eastern China

As the world's largest developing country, China's rapid economic development has caused more serious damage to the environment, and environmental pollution has become the number one problem in China's development. How to correctly deal with the coexistence of economy and environment is very important for the construction of our country. This paper analyzes the impact of urban design on regional ecology and how these influences can be evaluated, using a high-density city in eastern China as an example. This study takes the layout structure, spatial structure, facility support, flow organization and environmental ecology of the urban space as the direct carrier, and the cultural integration and technical response as the indirect carrier, and carries out the corresponding urban design in the above-mentioned space through the corresponding principles, strategies and methods. The impact of these elements on the urban ecological environment was also analyzed. The results of the study show that the ranking of ecological environment quality score in Anhui Province has been rising, and the number of the top five regions has increased from 20% to 80%.
