Using Guangdong Province as a case study, we utilized expressway online toll collection data to create networks of passenger and freight flows, examining differences through network analysis and the Random Forest algorithm.The findings are summarized below. Passenger and freight flows largely adhere to a Pareto distribution. Passenger flow networks exhibit higher density and cohesion than freight networks. The lognormal function is the most suitable model for depicting the distance decay pattern of passenger flows, whereas the power function offers the best fit for freight flows. The range of passenger flows is concentrated within 0∼40 km, whereas the range for freight flows is 0∼100 km. From a spatial perspective, a notable spatial agglomeration effect is observed in passenger flows, which primarily concentrate along both sides of the Pearl River Estuary. Additionally, population factors exert a more substantial influence on passenger flows, whereas labor force and enterprise factors significantly impact freight flows. This study deepens our understanding of expressway transport and supports vehicle classification control and collaborative traffic governance.</div></div>","PeriodicalId":48396,"journal":{"name":"Applied Geography","volume":"179 ","pages":"Article 103615"},"PeriodicalIF":4.0,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143817715","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}

The network accuracy was verified with biodiversity data, and policy suggestions were proposed according to land use analysis and related adjustment costs. The results show that wilderness suitability decreases from southeast to northwest. Large core areas are in the southeast, whereas corridors traverse the northwest, connecting relatively small, scattered, and wide core areas. Although the spatial network covers 25.69 % of the total area, 56.4 % of the carnivore records and 69.88 % of the mammal records are in this area. Most land types within the network are forests and grasslands; however, certain artificial surfaces and crop lands must be adjusted to enhance connectivity. Considering the adjustment costs, nonecological lands within corridors should be prioritized for transformation.

Moreover, spatial heterogeneity could act as a moderating variable, strengthening the negative association between housing precarity and life satisfaction. This study advances the importance of considering the housing precarity concept in understanding the life satisfaction of migrant private renters.

This approach has faced criticism, primarily due to its ecological implications. In response, a niche market has developed around so-called ‘natural’ or ‘low-intervention’ wines, emphasizing environmentally conscious production methods, resulting in a distinctive product. In a qualitative research approach, we explore the alternative practices which reflect the winemaker's care for soil and plant health, support microorganisms in the must, and preserve the wine's ingrediencies. Through practices like no-till, soil fertilization, and spontaneous fermentation, low-intervention winemakers aspire to stop soil degradation, regenerate their plants' microbiome and respect the grape's indigenous fermentation capacity, allowing in-situ yeasts to do their job and craft an individual wine flavour.

The study identifies prevalent hospital clustering in China, characterized by specific morphology, land use, and institutional composition. Higher hospital clustering occurs in cities with low financial capacity, low per capita income, and advanced medical technologies. Land use and locational attributes are key factors in hospital clustering, while transport services play a lesser role.

Three major findings were derived from Difference-in-Difference modeling and behavior grouping: (1) Individual daily activity spatial fixity exhibit a U-shaped distribution with age, revealing the 30–34 age group with the lowest fixity. Consistent levels of spatial fixity are observed as time progresses and individuals transition into specific age stages. (2) The multi-scale behavior framework elucidates over 40 % of the variation in daily activity spatial fixity over one and four-year intervals, and the result highlights the significance of integrating higher-scale behavioral dynamics over extended period. (3) Distinct behavioral change trends before and after the age of 35 result in the U-shaped curve of spatial fixity evolution.
