As US-China rivalry shifts focus to the "Indo-Pacific," the US's "Indo-Pacific Arc" disrupts regional stability. This paper applies "territorial trap" theory to develop a geopolitical influence model integrated with the wedge strategy. Analyzing spatiotemporal changesin US and Chinese influence within the "Indo-Pacific Strategy" region provides recommendations for China. Findings: 1) Overall US-China influence evolved through "low volatility" (2011—2015), "medium convergence" (2016—2018), and "high stability" (2019—2021) phases, with China's influence growing 11.2% annually; 2) Country-level analysis shows three power evolution types: stable, reversal, fluctuation; 3) Geopolitical categorization reveals US advantage (Australia, Philippines, Japan, New Zealand), China advantage (Indonesia, Malaysia, Vietnam, Brunei), and balanced influence (India, South Korea, Thailand, Singapore); 4) Influence model factors align with wedge strategy methods. Strategically, China should prioritize reward wedges in advantage zones and mixed coercive/reward strategies elsewhere.

Traditional geography has long focused on spatial heterogeneity characteristics and the mechanisms of geographic environmental effects in subjective well-being research. However, the research paradigm based on static neighborhood effects has significant limitations, particularly in neglecting the dynamic impact of individual spatial mobility on geographic environmental exposure. This paper first systematically reviews the concepts and measurement methods of subjective well-being, elucidates the theoretical origins of geography's involvement in subjective well-being research from the perspective of disciplinary development history, and critiques studies on the relationship between geographic environments and subjective well-being. Secondly, based on philosophical and methodological innovations, it proposes a shift in the paradigm of geographic subjective well-being research towards spatiotemporal behavior. That is, from static locational analysis to dynamic behavioral tracking, from environmental determinism to human-environment interaction theory, and from cross-sectional studies to process research. Thirdly, the paper constructs a geographic research framework for subjective well-being based on the coupling of time, space, and human behavior. It also outlines future research directions from three dimensions of theoretical construction, pattern and mechanism mining, and innovative application scenarios. This provides theoretical support for building a perceptible and quantifiable evaluation system for happy cities, aiming to offer references for the formulation of happy city policies and refined urban governance.

Farmers are vital for preserving traditional villages and promoting tourism, and their livelihoods deserve priority in sustainable development. This study, based on two villages in Suzhou's Wuzhong District, assesses livelihood capital and stability, applies a coupling coordination model to evaluate their relationship, and uses regression to identify key factors. Findings show: 1)Tourism-related livelihood strategies enhance livelihood capital. Tourism-exclusive households rank highest in livelihood capital, followed by tourismoriented, labor-oriented, balanced-income, and agriculture-oriented ones. 2) Livelihood stability and coupling coordination have an inverted U-shaped link with tourism involvement. 3) Different livelihood capitals affect coordination differently but generally have positive impacts. 4) Strengthening financial and social capital is vital for enhancing farmers' sustainable capacity.

In recent years, the phenomenon of city walking has emerged in several Chinese cities, reflecting the lifestyle pursuits of urban youth. This provides a new context for exploring the relationship between the individual self and place in everyday life. Inspired by a humanistic geographical perspective, this study uses participatory observation and semi-structured interviews to gather data. The findings are as follows: First, through interaction with the locale, the everyday life spaces of city walkers become objectified. Secondly, the process of urban objectification brought about by city walking is accompanied by a process of self-objectification, where the "emergingself" and the "obscured self" coexist and transform into each other.Lastly, as both the self and the city are objectified, they enter a dynamic state of being simultaneously connected and detached, and city walking provides a way to potentially bridge these elements in daily life. These findings reveal interactions between the self and the world, bridging theoretical perspectives such as David Seamon's"Triad of Environmental Experience" and Yi-Fu Tuan's "Urban-Self" concepts, and also contribute to theoretical scope of domestic everyday life geography.

"Local revitalization" refers to emphasizing the importance of "local" based on the regional characteristics of traditional villages, highlighting regional differences, and integrating the local reality to achieve protection and development tailored to the specific context of the village. To enhance the local relevance and suitability of traditional village protection and development, local revitalization is an important approach for promoting the dynamic development of traditional villages, as well as a significant initiative in response to the rural revitalization call. Based on grounded theory and in-depth field surveys, this study uses three different types of traditional villages in the Loess Plateau hilly region of central Gansu as examples to explore the local relevance and adaptability in the protection, development, and revitalization practices of traditional villages, aiming to provide guidance on the revitalization direction for villages in the region. The research findings indicate that: 1) The five practical paths—culture, industry, population, landscape, and mechanisms—align with the actual development needs of traditional villages in the Loess Plateau hilly region and reflect the basic demands of the local population. Among them, population and industry are the core factors for promoting the dynamic development of traditional villages in the Loess Plateau hilly region, while culture and landscape are key to revitalization, and mechanisms ensure the success of the revitalization process. 2) By constructing five local revitalization paths—"culture-industry-population-landscape-mechanisms"—the goal is to promote the dynamic development of traditional villages in the Loess Plateau hilly region. These include: local culture responding to the revitalization of Loess cultural characteristics; local industry responding to the revitalization of village economic development; local population responding to the revitalization of villagers as the main agents; local landscape responding to the revitalization of settlements and ecological environments; and local mechanisms responding to the revitalization of governance mechanisms. (3) Through empirical analysis of different types of villages, five local revitalization paths centered on "culture-industry-population-landscape-mechanism" were formed. These five paths not only align with the real-world context of protecting and developing three different types of traditional villages but also represent the future development direction of traditional villages in the region. The aim is to enhance the local relevance and suitability of traditional village protection and development in the Loess Plateau hilly region, jointly promoting the dynamic development of traditional villages.
