First, descriptive statistics and network theory are applied to identify the spatiotemporal evolution across different outbreak phases. The Prophet model is then introduced to evaluate short-term responses, and the copula theory to analyze behavioral preferences. Results indicate increased count and decreased duration during small outbreaks, contrasting with broader pandemic observations. Although DBS activity is most localized during the outbreaks, it expands eastwards into wider urban peripheries, showing community merger and growth. Notably, network communities reveal distinct spatiotemporal behaviors compared to grid-based analysis, offering new perspectives for targeted strategies. Travel behaviors vary with rising cases within a week: trip count initially increases, then declines in the urban core, while trip distance and duration shorten in over half of the region. Probabilistic modeling, however, suggests that greater distances are more likely on days following new cases in western Shenzhen, highlighting the need for comprehensive analysis.

Our findings reveal a significant eastward expansion of dryland boundaries beyond the Hu-Huanyong line, increasing the number of cities within dryland regions, particularly large urban agglomerations.

The approach distinguished urban and rural ecological sources (ESs) based on the “morphology-quality-scale” framework and simulated distinct urban-rural ecological corridors (ECs) using the minimum cumulative resistance model, incorporating both general and urban-rural specific resistance factors.

The method was applied to examine poverty reduction dynamics in Yunnan-Guizhou-Guangxi area (YGGA) of Southwest China. Across 328 county-level units, the average poverty incidence markedly decreased from 33.38% to 12.42% (2000–2019), characterized by three phases: widespread high poverty (2000–2005), uneven regional improvement (2006–2012), and transformative poverty reduction (2013–2019). Spatio-temporal analysis uncovered the transformation from highly clustered poverty to a more dispersed distribution. Through interpretable machine learning, the study analyzed 24 driving factors in three categories.

Empirically, our analysis utilizes survey data from 94,221 rural migrants across 172 prefecture-level cities, employing a multilevel logistic regression model. The findings indicate that neoclassical and structural perspectives provide limited explanatory power for the relationship between healthcare accessibility and rural migrants’ identity integration at the city level. Our analysis revealed that enhanced healthcare access significantly strengthens identity integration, particularly in cities with limited medical resources or challenging living conditions, such as severe air pollution and inadequate green spaces.

Unlike prior studies, it employs multidimensional indicators to examine urban form alongside inequality and population density, addressing both spatial and statistical dimensions. Using Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) models, this study evaluates socio-spatial inequalities across 111 neighborhoods. Results reveal that compact neighborhoods generally exhibit lower social and spatial inequality due to better access to urban services, while sprawling areas, particularly in the periphery, face significant inequities. For instance, a one-unit increase in compactness correlates with a 15.2% reduction in social inequality and a 40.5% reduction in spatial inequality. However, the effects of population density vary across neighborhoods; higher density in marginalized areas may exacerbate inequality, necessitating context-sensitive planning. The findings underline the importance of promoting compact urban forms while addressing socio-economic disparities. Recommendations include tailoring urban planning policies to local contexts, improving infrastructure in marginalized neighborhoods, and enhancing service distribution to achieve spatial equity. This research highlights how urban form interventions can mitigate inequalities, contributing to sustainable and resilient urban development in rapidly urbanizing regions like Ahvaz.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"176 ","pages":"Article 103532"},"PeriodicalIF":4.0,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143345504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
