Evaluation of the Environmental Quality of Human Settlements in Fuzhou Based on Multi-Source Data

Evaluating the living environment within the city helps to find the problems exposed in the urban development, make the adjustment and improve the urban environment. However, most current studies focus on macroscale. This paper takes the downtown area of Fuzhou as the research area, the microscale residential area as the research unit, using multisource data such as meteorological monitoring data, remote sensing images, points of interest data (POI), population-kilometer data, land planning data, to construct the urban livability evaluation system from five aspects: environmental health, economic prosperity, traffic convenience, urban safety and public service facilities. The TOPSIS method was used to conduct a comprehensive evaluation of livability. The result shows that the overall quality of the residential environment is generally high in the central area and low in the marginal areas. More concretely, the areas with high level of human settlement are mainly distributed in most area of Taijiang District, the central and eastern part of Gulou District, the junction of Jin'an, Gulou and Taijiang Districts, Nantai Island in Cangshan District; the areas with low level of human settlement equality are mainly distributed in the marginal area of downtown.
