“…The current construction of new cities seeks speed and quantity and does not invest enough in shaping the spatial hierarchy, resulting in a new city skyline with a single hierarchy, lacking rhythm and cultural connotation, and disconnected from the old city and the natural environment. A city's unique skyline can serve as a representative image of the city, and in the above context, the study of the city skyline has strong practical significance [19]. Puspitasari A W et al obtained that linear clusters have higher visibility by comparing different layouts of circular, rectangular, and linear geographic area organisations in high-rise complexes [20].…”

“…Puspitasari A W et al obtained that linear clusters have higher visibility by comparing different layouts of circular, rectangular, and linear geographic area organisations in high-rise complexes [20]. Mehrdad Karimimoshaver et al used respondents' judgments of colour images of the skyline on the three types of natural, traditional, and modern skylines and obtained that people preferred natural and traditional skylines [19]. Caner Guney et al considered Istanbul's skyline as a unique asset, and to maintain the original architectural composition of the skyline and to study the aesthetics of the city's skyline and its change as a result of tall structures, a study was conducted by using a GIS system for transformations that occur; this is achieved by customising the geographic model in a GIS environment [13].…”

The general population’s assessment and perception of a city can be influenced by its skyline, which is one of its representatives. This paper uses semantic segmentation and exploratory factor analysis to conduct a study from two different perspectives, aiming to analyse the development and current situation of the skyline of Hefei’s political and cultural new district. By collecting pictures of the skyline of the New Administrative and Cultural District, the New Administrative and Cultural District of Hefei’s skyline is being studied for overall changes using the semantic segmentation method, and to evaluate the quality of the skyline in various years, the entropy weight–TOPSIS is employed. Through the literature investigation and creation status of the new political and cultural district, the index system is scientifically formulated to conduct a questionnaire survey, and its reliability and validity are tested. This study is conducted with exploratory factor analysis of factors that are vital in the city skyline. The results of this study show that (1) after the semantic segmentation of the pictures, it is found that the proportion of buildings and the proportion of vegetation are both rising; the proportion of buildings tends to level off after 2018, and the proportion of vegetation shows a uniform increase. In the relative proximity ranking, the overall trend is increasing, and the skyline is ranked first in 2024. (2) Two variables were identified based on the findings of the exploratory factor analysis: ‘skyline value’ and ‘neighbourhood ecological quality’. The results of this study show that the skyline of Hefei’s New Administrative and Cultural District in 2024 is the best overall, and that the skyline of the New Administrative and Cultural District has developed into one of the city images of Hefei, and that its optimisation can be considered in terms of the “quality of the surrounding ecological environment”.

“…With respect to quantitative definitions, some progress was made since [59]. Several studies concentrate on one specific landscape element, e.g., walking path geometry [27] (having found that people tend to prefer curvy paths), oppressiveness due to building height [40], skyline impression [60], visual quality of urban water landscapes [61,62], and building exteriors [63]. Combined approaches include mostly landscape aesthetics indicators, e.g., [29], who developed beauty indexes and also distinguished landscape type; the morphologic scenic beauty estimation model of [64]; an aesthetic assessment approach [65]; and modelling of the aesthetics of urban-rural fringes [66].…”

Living in urban areas is the wish of many people. However, with population growth in those areas, quality of life has become a concerning element for achieving sustainable cities. Because quality of life is influenced by the built environment, the state of the latter is a fundamental issue for public policies. This research expands on previous research on the perceived pleasantness of built environments by presenting a large-scale case study of the urban layout pleasantness in the central area of Belo Horizonte, Brazil, a typical global south city, and correlating pleasantness scores with socioeconomic factors to understand whether people do in fact live where the urban layout is more pleasant and how pleasantness and socioeconomic factors relate and contribute to one’s choice of living location. A comparison with the city of Coimbra, Portugal, representative of the global north, was also carried out. The findings showed that pleasantness tended to correlate negatively with urban density and positively with income. Possible explanations for these results and their generality are advanced.

“…Of course, vegetation proportion and sky proportion cannot explain all the variations of visual effect scores. This means that, apart from the two main factors, the visual effect contains some more complex factors, such as the rhythm of the skyline [27,28], the color and style of buildings [29], and so on. With the Elo rating method, more detailed research on different factors of visual effect could be quantitatively discussed in the future.…”

The landscape visual effect of a city, which is generated by its long-term development, is an important index in city planning. In this study, we build a quantitative evaluation and remote sensing estimation scheme of landscape visual effect. The study contains two main steps. First, utilizing the Elo rating system and in situ sampled panoramic pictures, the quantitative assessment of the city landscape visual effect was carried out. Then, the landscape visual effect estimation model was built and applied to Landsat remote sensing image to generate the spatial distribution of landscape visual effect in Zhengzhou city, 2017. At last, the effect of different combination of land use and elevation to the landscape visual effect was discussed. The results showed the following: (1) the Elo rating system is an effective method to quantitatively evaluate the city landscape visual effect; (2) the landscape visual effect remote sensing estimation model had a good performance, with the mean absolute percentage error (MAPE) and root mean square error (RMSE) of the model are less than 0.05 and 80, respectively; (3) the landscape visual effect score of Zhengzhou city, 2017, was high in the southwest and low in the northeast; (4) different land use situation and average surface elevation had a complex influence on the landscape visual effect.
