Distribución espacial de las áreas verdes urbanas presentes en la ciudad de Quito

Abstract

Abstract: This study analyzes the spatial distribution of urban green areas in the Metropolitan District of Quito (DMQ) and its relationship with socioeconomic and demographic variables. Sentinel-2A Level-2A satellite images were used to obtain surface reflectance, and a shapefile from the Municipality of Quito was employed to classify green areas by typology. Vegetation indices (NDVI and SAVI) were calculated, and a spatial distribution analysis was performed using the "nearest neighbor" tool in QGIS. Accessibility to green areas was evaluated using the distance to nearest feature method with a point grid. Furthermore, population and socioeconomic data from INEC were integrated to analyze their relationship with green area distribution through zonal statistics and an ANOVA. Finally, the potential demand for green areas was modeled using multiple linear regression. The results show an uneven distribution of green areas in the DMQ, influenced by socioeconomic factors, and a potential demand that varies according to population density. This study provides relevant information for urban planning and green area management in Quitox.
