Intensive anthropogenic disturbances have driven significant spatial disparities and progressive fragmentation of forest-based green infrastructure (GI) that delivers vital ecosystem services across river basins. To address these challenges, delineating ecological management zones developing spatially targeted GI optimization measures are imperative for safeguarding regional security advancing nature-based solutions in coupled human–water–forest systems. Focused on the mainstream area Jialing River Basin, we establish an zoning system reconciles forest resilience with development equity. By using morphological pattern analysis, landscape analysis In-VEST model, supply capacity was assessed from three dimensions: element composition, structural configuration, services. The demand intensity evaluated based environmental governance pressure, urban expansion social needs counties. Supply–demand matching analyzed quadrant-based mismatch typology coupling coordination degree model. results reveal following: (1) supply-deficit counties predominantly located middle lower reaches basin, characterized by high urbanization economic development; (2) supply-surplus high-level balanced cluster ecologically conserved upper reaches; (3) low-level concentrated agricultural zones; (4) overall show a preliminary state coordination. Based findings, basin classified into five at county level: restoration, management, rehabilitation, enhancement, conservation. Tailored policies were formulated each zone to advance sustainable development.

Urban parks, as major components of green infrastructure, have contributed to natural landscape preservation, ecosystem service provision, residents’ physical and mental health enhancement, social cohesion intensification, under the emphasis on need for sustainable urban development. However, parks been insufficiently inappropriately created in process space expansion population density increase, necessitating their equitable distribution access. This study aimed analyze characteristics a total 354 Seoul, South Korea, utilizing estimates floating derived from big data park catchment areas, context 15-minute city. Its 25 districts were classified into following four types based relationship between area ratios 600 m 900 areas: Type 1 equitably distributed with well-matched supply demand; 2 had an uneven due insufficient excessive 3 inadequately both demand below average; 4 mismatch sufficient unfulfilled demand. suggested strategies improve spatial equity each type, including qualitative improvement, quantitative redistribution, accessibility optimization tactics.

Planners need to fully understand the quantity of land supply and its matching relationship with population demand, as these are prerequisites for urban greenspace planning. Most papers have focused on single cities parks, little attention paid comparative analysis between multiple a macro scale, ignoring influence spatial effects leading lack basis regional green infrastructure This paper selected 102 in Hunan province case studies comprehensively conduct empirical research using mismatch model geographically weighted regression method. The parkland characterized by significant heterogeneity correlation, demand should not be ignored, oversupply undersupply co-existing. influenced number factors, each factor has stronger latter than former. Different factors vary widely nature intensity their effects, dynamics more complex. Economic development, financial capacity, air quality key former having negative impact opposite (positive) effects. We suggest that when government allocates resources targets it formulate differentiated allocation plan based conditions city; besides, also place emphasis integration coordination support mutual cooperation.

Assessing the Spatial Equity of Urban Park Green Space Layout from the Perspective of Resident Heterogeneity

Sustainability, Год журнала: 2024, Номер 16(13), С. 5631 - 5631

Urban park green spaces (UPGS) are essential resources for improving the urban ecological environment and meeting residents’ recreational needs. However, during rapid urbanization, layout of UPGS often exhibits spatial inequity, with significant differences in enjoyed by resident groups different socioeconomic attributes. Accurately assessing equity (the equal accessibility UPGS) is crucial optimizing resource allocation promoting social equity. This study takes main area Nanjing as an example utilizes location-based service (LBS) data multi-source geographic to conduct in-depth characterization attributes, behaviors, space at street scale. By constructing indicators heterogeneity supply–demand matching degree, it reveals among locations explores correlation between The finds that generally poor central low-income communities. higher degree diversification attributes leads a lower level their streets. results big analysis verify impact on layout. issues from perspective heterogeneity, providing new ideas evidence resources. Future planning should pay more attention diversity needs, focus areas communities, balance interests demands stakeholders through public participation mechanisms.

Assessing the spatial equity of the aged care institutions based on the improved potential model: a case study in Shanghai, China

Frontiers in Public Health, Год журнала: 2024, Номер 12

Опубликована: Авг. 29, 2024

With the spread of an aging society, demand for aged care institutions among older adults is increasing. The inadequate supply and distribution have led to increasing concern about spatial equity in institutions. Most studies utilized accessibility assess from perspective, while perspective has received little attention. In addition, few evaluated at grid resolution. Therefore, this study takes Shanghai as example analyze both perspectives. By proposing improved potential model, a network resolution 500 × 500, more refined. results show that population are predominantly concentrated downtown area surrounding regions. However, obtained Lorenz curve Gini coefficient indicate allocation pension beds based on size proportional across different districts Shanghai. When considering quality indicators introducing energy model calculate accessibility, imbalance between regions still exists needs further optimization.

Demand-Led Optimization of Urban Park Services

Forests, Год журнала: 2023, Номер 14(12), С. 2371 - 2371

Опубликована: Дек. 4, 2023

As the demand for cultural and recreational services grows, mismatch between supply of park significantly affects residents’ well-being. Optimizing spatial layout is a focal point urban green space research. Taking Hangzhou, Zhejiang Province, as case study, this research analyzes patterns balance service demand. Utilizing Grey Wolf Optimization Model optimized by K-Nearest Neighbor (GWO-KNN), study proposes construction objectives optimizing services. The results indicate following: (1) significant differences exist in demands residents different residential environments; (2) there noticeable disparity among various areas with an overall positive correlation levels resident demands, yet imbalance exists; (3) categorizes types into low-service coordination, high-service imbalance, imbalance; (4) GWO-KNN applied optimization being innovative aspect study. Strategies each category are proposed: emphasizing suburban utilizing surrounding resources adding diverse facilities; introducing facilities friendly to vulnerable groups meet needs populations; enhancing complementary advantages “new” “old” cities moderately increasing sizes improving facility development levels; structure limited land construct network system. This aims provide theoretical technical support systems.
