Analysis of the impact of urban landscape ecological planning on haze based on GIS: a case study of Anshan city center

Abstract

With the further acceleration of China's urbanization process, atmospheric pollution is increasing, and haze occurs frequently throughout the country, exposing a series of urban planning problems in China's urban development, which pose new challenges and requirements for the future development of urban planning. In view of the direct causal relationship between haze and urban planning and management, we can put forward new planning ideas by exploring the relationship between the spatial distribution of urban planning and haze, so as to clarify the focus and development strategy of urban planning in the haze era. The application of modern geographic information technology can optimize the level of urban planning management, thus realizing the goal of modern urban planning. Based on the remote sensing data of Anshan City in 2016, this study divided the functional areas of the city, analyzed the air quality data of the study area for four consecutive months from November 2016 to March 2017, and analyzed the impact of the landscape ecological planning pattern of Anshan City on the spatial distribution of haze through GIS spatial analysis technology. The research shows that the urban landscape pattern of Anshan has a very important impact on the formation of haze. Future urban planning should be based on the implementation and management of urban spatial layout planning, energy planning, road system planning, green space system planning, transportation planning and wind corridor planning. This study provides a scientific basis for urban haze governance.
