To tackle these issues, this study introduces a novel two-step SI model that enhances travel flow predictions. This study utilises a k-means clustering algorithm to group areas based on residents' socioeconomic characteristics, then calibrates the localised distance-decay parameter in the origin-specific gravity model for each group and predicts the travel flows. Demonstrated by a case study of the Greater London Area (GLA), we uncovered local distance decay patterns in commuting trips and explained their associations with spatial structure and non-spatial factors using census data.

The results show that from 1990 to 2020, the population security level in border areas first increased and then declined, with an overall low level. There are significant variations in population security development types across different border areas, with growth rates gradually slowing and regional disparities narrowing. The population security level in border areas is influenced by various factors and exhibits significant spatial heterogeneity. To promote the coordinated development of border areas and safeguard national security, this paper proposes specific policy recommendations addressing population security issues and their underlying causes.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"179 ","pages":"Article 103643"},"PeriodicalIF":4.0,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899096","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}

As major contributors to China's economy and its carbon emissions, urban agglomerations play a critical role in reducing carbon emissions, and government interventions have attracted considerable attention. In this context, this study focuses on the spatiotemporal nonstationary characteristics of factors influencing carbon emissions in 19 urban agglomerations in China. Using the geographically weighted regression (GWR) model and its extensions, we analyzed the impacts of two government intervention factors—fiscal expenditure and green cover—on carbon emissions. A comparison of multiple models revealed that the geographically and temporally neural network weighted regression (GTNNWR) model best captures the spatiotemporal nonstationary relationships. Our findings indicate that increased government fiscal expenditure generally reduces carbon emissions, with stronger effects in the northern cities we studied. Urban green cover has significant negative impacts in the core cities of most urban agglomerations. However, these impacts may reverse in a very small portion of cities, possibly due to differences in development stages.

Our findings reveal that over the past two decades, built-up land expansion had significantly degraded habitat quality, and rural settlement expansion had a substantially greater negative impact on habitat quality compared to urban growth, particularly in areas with high rural population densities. The difference in impact is mainly attributed to the lack of unified planning in rural development, while urban follows strict, intensive, and green planning, with increasing emphasis on mitigating human activities’ impact on the eco-environment. Further projections indicate that the expansion rate of built-up land in China would slow down over the next 30 years, leading to a reduced impact on habitat quality. This study highlights the critical need for targeted policy measures to mitigate the ecological risks associated with rural expansion and provides valuable insights for more effective land-use planning and ecological conservation strategies.

This paper examines this phenomenon through optimal matching of patient population to healthcare facilities in two approaches representing top-down planning and bottom-up individual choice. More specifically, planning matching spatially assigns the patients to the closest facilities and choice matching, including multinomial logit matching or game theoretic matching, optimally selects facilities based on patient choices. Using Hangzhou, China as a test bed with 194 healthcare facilities and 588 residential communities, this research has found that: (1) the inconsistency between planning and individual choice leads to population bypassing certain facilities; (2) the trade-offs between healthcare service level and community-facility distance are consistent across matchings; (3) systemic planning outperforms individual choice concerning distance and actual utility while the reverse holds true for service level and indirect utility; (4) certain thresholds exist beyond which neither approach excels, suggesting a mix of the two approaches.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"179 ","pages":"Article 103641"},"PeriodicalIF":4.0,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143855445","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}
