Sustainability, Journal Year: 2025, Volume and Issue: 17(4), P. 1515 - 1515

Published: Feb. 12, 2025

Optimizing the habitat quality (HQ) assessment and revealing its nonlinear influence mechanisms, particularly by considering mountain micro-topographic characteristics, are critically important for promoting sustainable development safeguarding ecological environment of cities. Taking Chongqing main city (CMC) as study area, first, Geomorphons algorithm was used to identify positions. On this basis, HQ InVEST model optimized collecting multispectral data from UAV, spatiotemporal change trend analyzed least-squares method. Secondly, hotspot analysis explore differentiation on different land use geomorphological types. Finally, based generalized additive model, dominant influencing factors were determined, their effects analyzed. The results showed following: (1) average CMC an increasing 2000 2020. four mountains two rivers higher, while it lower in central urban area. (2) hotspots mainly distributed parallel areas composed forests, grasslands, waters. heterogeneity at scale manifested that summits always HQ. (3) influenced a range factors, including both natural environmental conditions socio-economic drivers, among which normalized difference vegetation index most factor.

How does mobility and urban environment affect the migrants’ settlement intention? A perspective from the intergenerational differences

Frontiers in Public Health, Journal Year: 2024, Volume and Issue: 12

Published: March 1, 2024

Introduction With China embracing a new people-centered urbanization stage, the problem of migrants “flowing without moving” has become increasingly prominent, and settlement intention gradually garnered attention. Methods Our research, based on questionnaire data from Labor Force Dynamic Survey 2016, uses multilevel linear regression model to explore influence mobility, social environment, built demographics characteristics in discusses differences between old generations their internal mechanism. Results The findings are as follows: (1) Compared generation, migrant generation generally higher intention. (2) migrants’ is influenced mainly by demographic characteristics. (3) For significantly (4) floating environment Discussion Finally, this paper argues that there mechanism same factors migrants. It proposes differentiated policy suggestions for promote city integration.

Ecological Security of Desert–Oasis Areas in the Yellow River Basin, China

Land, Journal Year: 2023, Volume and Issue: 12(11), P. 2080 - 2080

Published: Nov. 18, 2023

The desert–oasis interaction zone plays a crucial role in safeguarding oasis ecological security and maintaining stability within oases. This paper proposed framework of EN-DSS, based on long-term remote sensing data fundamental data, adopted morphological spatial pattern analysis (MSPA) Linkage Mapper among other methods, it took Lingwu City the Ningxia Hui Autonomous Region, which is located upper reaches Yellow River, as case study. results indicate following: since 1995, this system has exhibited characteristics whereby expanding eastward desert significantly receding. vegetation coverage improved overall, forming an characterized predominantly by shrub forests, referred to “one core, two corridors, three zones, multiple clusters” pattern. reduced risk wind sand erosion agricultural irrigation areas along River. However, construction still faces challenges, including high maintenance costs need enhance network’s quality. In future, will be necessary strengthen integrated network areas, urban regional system.

China's provincial optimum population sizes under SSP‐RCP scenarios

Population Space and Place, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 24, 2024

Abstract Climate change poses new challenges to achieving a balanced population distribution. Predicting the impact of development patterns using climate scenarios can offer more precise insights into environmental and social risks. By adopting possibility–satisfiability (P–S) model, this study investigates optimum sizes for 31 provincial districts China by 2035 2050 under seven shared socioeconomic pathway‐representative concentration pathway (SSP‐RCP) scenarios. Results indicate that SSP2‐4.5 scenario, which maintains current patterns, human (OHP) ranges from 985 million 717 in 902 623 at different P–S values, respectively. The SSP1‐1.9 SSP1‐2.6 promising prospects carrying largest size. Therefore, China's future depends on choosing sustainable path prioritizes growth OHP. provinces unbalanced routes SSP4‐3.4 SSP4‐6.0 are mainly limited economic development, while those regional competition route SSP3‐7.0 scenario both climatic pressures. Under fossil fuel SSP5‐8.5 deterioration imposes severe constraints scales eastern coastal area with high urbanization levels northwest harsh environments subject natural conditions. In addition, central western regions encounter size limitations due insufficient development. Notably, distribution remains concentrated east sparse west, flanking Hu Huanyong Line (Hu Line), minimal expected changes future. studying spatial SSP‐RCP scenarios, provides theoretical support government decision‐making context change.
