Insights from 30 Years of Land Use/Land Cover Transitions in Jakarta, Indonesia, via Intensity Analysis

Land, Год журнала: 2024, Номер 13(4), С. 545 - 545

Опубликована: Апрель 19, 2024

Here, we assess land use/land cover (LULC) transitions over the last 30 years in Jakarta, Indonesia. Land maps were prepared for 1990, 1995, 2000, 2005, 2010, 2015, and 2020 using seven categories of Landsat satellite image: bare land, built-up, cropland, green area, mangrove, water body, pond. LULC changes assessed through intensity analyses at interval transition levels. initially rapid (1990–1995) then more gradual (1995–2000, 2000–2005, 2005–2010). Unlike previous intervals, annual uniformly distributed time 2010–2015 2015–2020. Driven by high population economic growth, built-up was identified as an active gainer all intervals except 2010–2015. Alongside areas, cropland main supplier other categories, including pond, areas. The largest area occurred pond areas during 2005–2010 High demand observed driven growth triggered necessity. Economic exhibited a positive correlation (R2 = 0.78, t 9.996). This study elucidates spatiotemporal patterns rapidly growing city.

Spatio−Temporal Changes and Key Driving Factors of Urban Green Space Configuration on Land Surface Temperature

Forests, Год журнала: 2024, Номер 15(5), С. 812 - 812

Опубликована: Май 4, 2024

Changes in land cover by rapid urbanization have diminished the cooling effect of urban green spaces (UGS), exacerbating upward trend surface temperature (LST). A thorough and precise understanding spatio-temporal characteristics UGS LST is essential for mitigating localized high temperatures cities. This study identified changes configuration Shanghai from 2003 to 2022. The correlation between was explored using spatial autocorrelation analysis causal inference. results show that (1) high-temperature space had grown 721 km2 3059 2022; (2) suburbs, largest area tended decrease, while number patches increase, indicating a distinct feature suburbanization; (3) more significant correlation, sprawl primarily impacts large UGSs; (4) compared shape UGS, are key factor influencing regional LST. These findings enrich knowledge spatio−temporal relationship its urbanization, offering valuable insights building cooler

Decoding the Role of Urban Green Space Morphology in Shaping Visual Perception: A Park-Based Study

Land, Год журнала: 2025, Номер 14(3), С. 495 - 495

Опубликована: Фев. 27, 2025

Urban green spaces, vital public infrastructure, have received limited research on how their morphology affects visual perception preferences. Using data from ten parks, we generated space maps high-resolution satellite imagery and calculated indicators, such as quantity, fragmentation, connectivity, shape complexity. By combining the Mask2Former image segmentation deep learning model with a multi-objective regression structural equation modeling, analyzed relationship between preferences, controlling for geographic demographic factors. The results showed that spaces tighter aggregation, continuity, complexity led to more distinct perceptions. This was mediated by proportion of landscape elements. distribution, shape, connectivity urban had an independent impact individual perception, far exceeding influence quantity alone. spatial should be incorporated into health-oriented design, exploring global interest in human well-being, providing valuable insights planning health-driven design.

System-based approaches are critical for addressing the complex and interconnected nature of urban ecological development restoration ecosystem services. This study adopts a system perspective to investigate spatiotemporal drivers key services, including carbon sequestration, water conservation, sediment reduction, pollution mitigation, stormwater regulation, within Yangtze River Delta Eco-Green Integrated Development Demonstration Area (YRDDA) from 2000 2020. We propose novel framework defining enhanced-efficiency service management regions (EESMR) guide targeted restoration. Our analysis revealed interplay 11, 9, 6, 10 driving factors selected highlighting heterogeneity these drivers. By overlaying factors, we identified high-efficiency priority areas EESMR that ensure high returns on investment efficient functions. system-oriented approach provided spatial guidance integrated restoration, green development, eco-planning. These findings offer valuable insights policymakers planners in other rapidly urbanizing regions, supporting formulation effective land-use policies balance environmental sustainability growth.

Forests, Год журнала: 2024, Номер 15(10), С. 1719 - 1719

Опубликована: Сен. 28, 2024

The effect of urban green spaces on traffic noise reduction has been extensively studied at the level single vegetation, hedges, etc., but there is a lack corresponding studies scale spatial patterns spaces. Therefore, this study aims to analyze relationship between pattern space and change in space’s capacity. Through morphology analysis method, divides Fuzhou high-tech zone into seven types elements with different ecological definitions simulates condition environment presence as well without by computer simulation, calculates distribution map produced space, analyzes correlation geographically weighted regression modeling analysis. finds that (1) Urban can significantly affect net space. Areas high coverage produce stronger effect. (2) More complex shapes more fragmented higher reduction. (3) close source exert process planning design, from perspective improving acoustic environment, configuration high-quality areas levels pollution should be given priority, which may have better effects.
