Evaluation of Spatial Pressure in High Density Residential Areas

It is important to understand how landscape elements affect the spatial oppression of people as high-density areas are increasing due to the limited space availability in cities. Therefore, we carried out a statistical analysis of the questionnaire survey result which was obtained from residents of the high-density areas in Xuzhou, China. From the literature review, we defined 9 landscape elements including the density of buildings in residential areas, duration of sunshine acceptable to residents, the skyline of sight opening, the proportion of the sky in the picture, a sense of closeness between buildings, the sense of distance between buildings, open area, area proportion of green vegetation, and types of green vegetation analysis. We analyzed the correlation and linear relationship of the elements with the spatial oppression of the respondents. The results show that there is no significant positive correlation between the proportion of the sky in the picture and space oppression, but the other 8 elements are significantly correlated with spatial oppression. Especially, the density of buildings in the residential area, the time that residents can accept sunshine, the openness of the skyline of sight, the sense of closure between buildings, the sense of distance between buildings, the open area, the area ratio of green vegetation, the types of green vegetation and spatial oppression are more significant factors to affect spatial oppression.
