Spatial Characteristics of Multidimensional Urban Vitality and Its Impact Mechanisms by the Built Environment

Land, Journal Year: 2024, Volume and Issue: 13(7), P. 991 - 991

Published: July 5, 2024

Urban vitality, intricately connected to urban morphology, has long been a cornerstone of planning and design. The accelerated pace urbanization created abundant living working spaces, but it also brought about series issues such as traffic congestion, environmental pollution, insufficient public uneven development, leading decline in vitality. spatial distribution patterns vitality their influencing factors are diverse vary across different cities, necessitating multidimensional exploration the relationship between built environment. Utilizing central area Beijing case study, this research leverages multi-source data delineate characteristics social, economic, cultural, comprehensive Furthermore, set built-environment indicators is developed five dimensions analyze correlation with results indicate: (1) There significant clustering various types Beijing, pronounced high-density population aggregation vigorous economic activities. (2) Subdistricts exhibiting high social display an “n”-shaped around Second Ring Road. In contrast, those concentrated along Chang’an Street district commercial centers. High cultural subdistricts distributed northwest–southeast trajectory from Fourth Road Road, exhibit concentric radiating outwards center. (3) Social most closely related Beijing’s develop relatively evenly. (4) environment significantly affects all Factors floor ratio, POI density, mixing degree, intersection density fundamental enhancing whereas greening rate somewhat inhibits it. (5) Future should utilize effect high-vitality optimize distribution, enhance mixing, increase metro station strengthen critical structures for synergistic development.

Influencing Factors of Street Vitality in Historic Districts Based on Multisource Data: Evidence from China

ISPRS International Journal of Geo-Information, Journal Year: 2024, Volume and Issue: 13(8), P. 277 - 277

Published: Aug. 5, 2024

Amid urban expansion, historic districts face challenges such as declining vitality and deteriorating spatial quality. Using the streets of Xi’an’s historical cultural district examples, this research utilizes multisource data, including points interest (POIs), street view images, Baidu heatmaps, alongside analytical techniques machine learning. This study explores determinants from dual perspectives its external manifestation carriers. A quantitative framework for measuring in is established, thoroughly examining driving factors behind vitality. Additionally, relationship between built environment indicators elucidated through statistical analysis methods. The findings reveal significant, time-varying influences these carriers on human vitality, with distinct distribution patterns activity across different times, significance influence representations various types varies over time. Based insights, paper proposes strategies enhancing streets, aiming to rejuvenate sustain diverse dynamic energy districts. It provides a foundation revitalizing vigor heritage zones offers applicable similar contexts.

Comparative Spatial Vitality Evaluation of Traditional Settlements Based on SUF: Taking Anren Ancient Town’s Urban Design as an Example

Sustainability, Journal Year: 2023, Volume and Issue: 15(10), P. 8178 - 8178

Published: May 17, 2023

Sustainable urban forms (SUF) guide spatial creation, significantly revitalise the development of traditional settlements, and are an essential theoretical support for design. At same time, emergence quantitative analysis technology further promotes visualised evaluation performance vitality in However, current research rarely studies settlements with from SUF perspective. Therefore, this takes Anren Ancient Town Chengdu, Western China, as example to propose a design based on sustainable form theory raise local vitality. Then, it introduces system index (UFI) three measurement methods: Space Syntax, Spacemate, MXI, conducts comparative Town’s status quo explain process how scheme came about. The results found that proposals principles compactness, mixed land use diversity guidelines can effectively improve settlements. high settlement could be achieved by combining SUF-based UFI-based systems. assist optimise decision-making act paradigm or regeneration towns.

Uncovering the factors influencing the vitality of traditional villages using POI (point of interest) data: a study of 148 villages in Lishui, China

Heritage Science, Journal Year: 2023, Volume and Issue: 11(1)

Published: June 9, 2023

Abstract Improving vitality has been a major bottleneck in the revitalization of traditional village heritage worldwide. The (VTV) varies greatly depending on socioeconomic factors and natural conditions. Significant spatial variation exists VTV, even within same urban jurisdictions China; however, main determinants for this have not yet quantified owing to difficulty obtaining data from large rural samples, making targeted invigoration difficult. Thus, we applied point interest data, which are easily accessible big bridge source gap. To assess VTV’s influencing analyze variations among factors’ impacting intensity, used Ordinary Least Squares Geographically Weighted Regression models conducted empirical studies involving 148 villages Lishui, China. Seven influenced study area, with most significant being topographic relief, elevation, scenic spots commercial industry. Moreover, intensity varied by region. Topographic relief elevation had greatest impact north south whereas primary education, transportation facility agricultural bases north, industry middle Lishui. Taken together, method makes sample factor analysis feasible, global implications, can provide foundation scientific precise regional promotion is beneficial revitalization.

Transformations in Urban Human Settlements Within China’s Sustainable Development Innovation Demonstration Zones: A Case Study of Chenzhou City, Hunan Province, During Rapid Urbanization

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 431 - 431

Published: Feb. 19, 2025

The quality of urban human settlements (UHSs) directly affects the city’s livability and well-being its residents. Scientific monitoring assessment UHSs, their progress toward sustainable development, impacts they experience from rapid urbanization can accelerate implementation United Nations development goals (SDGs) in field settlements. This study focuses on Chenzhou City, an innovation demonstration zone for China’s Sustainable Development Agenda. It develops a evaluation index based SDG 11 (Sustainable Cities Communities), 6 (Clean Water Sanitation), other relevant SDGs, with objectives residential stability, facilitated mobility, safety residents, comfortable environment, low-carbon development. Solutions Network (SDSN) methodology was utilized to assess City 2015 2022, focusing UHS indicators, targets, (SDI) scores. geographic detector techniques were employed investigate impact new UHSs. analysis found following: (1) After established (2019–2022), scores five SDI increased by over 50% compared pre-establishment period (2015–2018), highly significant difference between two periods. (2) Among 35 indicators measured, proportion those that reached or nearly targets 57.1% 2018 71.4% 2022. As there has been positive goal while efforts four have made some but require further acceleration.
