Remote Sensing, Journal Year: 2025, Volume and Issue: 17(2), P. 211 - 211

Published: Jan. 8, 2025

The rapid construction of expressways in China has brought significant economic and social benefits, but it also imposed substantial ecological pressures, particularly sensitive regions. Landscape risk assessment, as an important means to predict measure the adverse effects human activities on environment, is being paid more attention. However, most studies focus static landscape mosaic pattern lack dynamic analysis. Moreover, they mainly effect road operation stage, ignoring monitoring analysis whole process. Based this, current study examines land use changes along Linghua Expressway Gansu Province using high-resolution GF-1 remote sensing imagery. A assessment (LERA) model was employed quantify assess risks before after expressway between 2018 2022. results revealed a decrease cropland forest land, accompanied by increase grassland areas. index decreased from 0.318 0.174 2022, indicating improvement resilience. high-risk zones remain near expressway, emphasizing need for continuous proactive management strategies.

Green Space Equality Is Better in Fast-Growing Cities: Evidence from 140 Cities in China

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 366 - 366

Published: Feb. 10, 2025

Given the critical role of urban green space (UGS) in fostering sustainable development, there is a growing focus on assessing levels and inequalities exposure. However, integration UGS with particularly context China’s unique national conditions, remains underexplored. This study evaluates adequacy equity provision 140 Chinese cities (with built-up areas exceeding 100 km2) using metrics such as percentage space, exposure, Gini coefficient. Additionally, investigates interplay between natural, economic, social factors variables, examining interrelation urbanization development within framework distinctive land finance policy. The findings reveal that most large suffer from inadequate inequitable provisions, clear connection these deficiencies. highlights favorable natural economic growth, urbanization, living transfer system China can enhance exposure equality. research offers valuable insights evidence for central local governments to devise effective greening strategies, aiming attain high-quality development.

Filling in the Spaces: Compactifying Cities towards Accessibility and Active Transport

ISPRS International Journal of Geo-Information, Journal Year: 2023, Volume and Issue: 12(3), P. 120 - 120

Published: March 9, 2023

Compactification of cities, i.e., the opposite urban sprawl, has been increasingly presented in literature as a possible solution to reduce carbon footprint and promote sustainability current environments. Compact environments have higher concentrations interaction opportunities, smaller distances them, potential for increased active mode shares, leading less transport-related energy consumption associated emissions. This article presents GIS-based quantitative methodology estimate on how much can be gained that respect if vacant spaces within city were urbanized, according municipal master plan, using four indicators: accessibility, modal share, transport consumption, 15-minute analysis. The is applied case study, which Coimbra, Portugal, compact version itself are compared. Results show layout improves all indicators, with averages per inhabitant improving by 20% 92%, depending scenario assumed cycling, more equitable.

Social Network Analysis Reveals Spatiotemporal Patterns of Green Space Recreational Walking Between Workdays and Rest Days

Urban Science, Journal Year: 2025, Volume and Issue: 9(4), P. 111 - 111

Published: April 4, 2025

Growing concerns about the negative impacts of high-density built environments on residents’ physical and mental health have made optimizing recreational walking networks in green spaces a crucial issue for improving urban public service efficiency. While previous studies largely focused static accessibility measures, these methods cannot capture actual human behaviors temporal variations space usage. Our research introduces novel social network analysis methodology using GPS trajectory data from Shanghai’s Inner Ring Area to construct compare during workdays rest days, revealing dynamic spatiotemporal patterns that traditional miss. Key findings include: (1) At node level, different sizes play differentiated roles network, with large-scale serving as destination hubs while pocket function critical connecting points; (2) regional workday show more dispersed spatial distribution higher modularity, day form clusters central area; (3) overall demonstrate density diversity, reflecting expanded activity range diverse preferences. Green management should focus value networks. These provide theoretical methodological support transitioning “static equity” “dynamic justice” system planning, contributing development inclusive resilient

Community-Level Urban Green Space Equity Evaluation Based on Spatial Design Network Analysis (sDNA): A Case Study of Central Wuhan, China

International Journal of Environmental Research and Public Health, Journal Year: 2021, Volume and Issue: 18(19), P. 10174 - 10174

Published: Sept. 28, 2021

Urban green spaces (UGSs) provide numerous irreplaceable environmental and social benefits to humankind, but the lack of baseline information makes it difficult propose a reasonable greening strategy so as achieve an equitable allocation community spaces. This paper divides UGSs into three classes using spatial design network analysis (sDNA) quantifies UGS accessibility communities in central Wuhan. Based on these results Gini coefficient, we analyze equity distribution at level, then future strategies both city levels. The show that railway station old Wuhan are core areas traffic strength (TNS). evenly distributed TNS, number non-core is small, their relatively uneven, with medium largest, carrying densest residential population. Most perform well terms equity, 163 communities, covering population more than one million, remains be improved. method conclusions this study will contribute policy making 965 Wuhan, thus promoting orderly planning high-quality construction living circles.

Urban sprawl in China presents unique characteristics that differ from those commonly studied Western contexts, an aspect not fully explored previous studies. Therefore, taking Wuhan, Hubei as example and integrating population data, remote sensing POI this research offers a perspective on development urban China. By incorporating population, land use, amenities, study measures their dynamics to classify spaces employs spatial regression models identify the of with effects controlled. It further applies geographically weighted examine underlying heterogeneity. The findings indicate growth expansion do align perfectly, exploration identifies various trends core periphery areas. On other hand, some suburban areas show compact trends, but local amenities may be limited due historical legacies. Regression results reveal specific development. Key include following: (1) shaped by triple process renewal, suburbanization, rural revitalization, Wuhan shows significant core-periphery structure trend polycentricity; (2) overcrowding central districts is primary driver development; (3) most traditional suburbs have emerged consequence rapid urbanization legacy (4) heterogeneity across highlights necessity for locally tailored approaches regulating
