Exploring Suitable Urban Plant Structures for Carbon-Sink Capacities

Land, Journal Year: 2025, Volume and Issue: 14(4), P. 849 - 849

Published: April 13, 2025

Urban parks, a type of urban green space, help mitigate environmental pollution and climate change by absorbing storing atmospheric carbon. Optimizing their carbon-sink capacity requires thoughtful plant community design considering multiple factors. This study analyzed South Korean parks using QGIS i-Tree Eco, integrating satellite imagery with field surveys at both spatial tree scales. Park spaces were classified into six types based on the biotope criteria established in this study. Random forest regression was applied to each identify key variables influencing annual carbon sequestration storage. The relationship between maturity examined for ten dominant species, offering insights selection. Higher coverage more deciduous species linked efficiency While variable importance varied slightly across types, density most influential sequestration, diameter breast height age These findings provide integrated short-term long-term storage, as well strategic directions structuring communities ecosystems. offers empirical evidence designing carbon-efficient contributing sustainable landscape strategies.

The global climate crisis is escalating, and urban living Space (ULS) a significant contributor to carbon emissions. How improve the suitability of ULS while promoting social economic development issue. This study aims develop an evaluation system for comparing analyzing inequality spatial differences in different areas. To achieve this goal, space index (ULS-CSI) based on organizational (SOI) has been proposed. ULS-CSI was calculated at area scale Tianjin using information from Land Use Database 2021. emissions coefficient method used calculate (ULSCE). Moran’I LISA analysis were quantify ULS-CSI. results showed that residential (RLA) highest scale, with 1.14 × 10 11 kg, accounting 33.74%. green leisure (GLA) absorption 5.76 5 32.33%. SOI areas have heterogeneity as such building area, road network density land use characteristics are significantly Areas superior CSI primarily situated Heping, Hexi, Nankai, Beichen, 83.90%. Conversely, under basic threshold included Xiqing, Jinnan, Dongli, 16.10%. Spatial portrayed positive correlation, indicating autocorrelation degree 500 m, Moran ’I value 0.1733.

Analyzing the Supply and Demand Dynamics of Urban Green Spaces Across Diverse Transportation Modes: A Case Study of Hefei City’s Built-Up Area

Land, Journal Year: 2024, Volume and Issue: 13(11), P. 1937 - 1937

Published: Nov. 17, 2024

With the increasing demands of urban populations, achieving a balance between supply and demand in spatial allocation green park spaces (UGSs) is essential for effective planning improving residents’ quality life. The study UGS has become research hotspot. However, existing studies rarely simultaneously improve side, transportation methods that connect two, nor do they conduct comprehensive, multi-dimensional evaluation. Therefore, this evaluates accessibility within Hefei’s built-up areas, focusing on age-specific incorporating various travel modes, including walking, cycling, driving, public transportation. An improved two-step floating-catchment area (2SFCA) method applied to evaluate areas. This evaluation combines assessments using Gini coefficient, Lorenz curve, location entropy, local autocorrelation analysis, utilizing ArcGIS 10.8 GeoDa 2.1 platforms. Together, these enable supply–demand analysis UGSs identify areas needing improvement propose corresponding strategies. results indicate following: (1) from regional perspective, there are significant disparities center, with old city showing more imbalance than new city. Areas high low primarily concentrated city, which require future improvement; (2) terms higher-speed (such as driving) offers better equitable compared slower modes walking), highlighting critical factor influencing accessibility; (3) regarding population demand, an overall UGS, imbalances observed needs residents across different age groups. Due specific among older people children, levels two groups consistent. valuable insights balanced, efficient, sustainable development social benefits UGS.
