Our findings indicate that: (1) regional integration can significantly reduce air pollution at the county level; (2) the environmental impact of regional integration is heterogeneous, influenced by regional differences, administrative constraints, and industrial foundations; and (3) regional integration reduces air pollution through advancing industrial structure and technological innovation, along with spatial spillover impacts. Therefore, policymakers should attach importance to air quality governance in counties, deepen regional integration strategies, optimize industrial structures, enhance technological innovation, and strengthen collaborative environmental governance to continuously promote regional sustainable development.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"24 1","pages":"Pages 77-93"},"PeriodicalIF":4.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings show that stakeholders at the provincial level, as well as those from the Ali and Naqu prefectures and six counties, place greater emphasis on institutional and resource-related needs than on other categories (attention score: 7.0–9.3 vs. 5.0–7.0). In contrast, stakeholders from the 73 protection stations prioritize technological and capacity-building needs more strongly than other types (attention score: 8.0–9.0 vs. 4.0–8.0).

Most of the eight existing protection measures were found to indirectly support broader climate adaptation efforts. In particular, protective actions addressing fire, pests, and weather-related disasters can be classified as autonomous adaptation, while other measures generate outcomes that enhance adaptation capacity under specific conditions. Adaptation options, grouped into three main types and 13 subcategories, differ across stakeholder groups, although substantial overlap exists between these options and current protective actions, including ecosystem-based adaptation strategies, adaptation-related practices, autonomous adaptation measures, and emergency interventions.

Upstream development has intensified soil erosion, and industrial and agricultural pollution in the middle reaches has degraded water quality. Rapid urbanization has further caused habitat fragmentation and biodiversity loss. Collectively, these challenges threaten human well-being and hinder sustainable development, making the construction and optimization of an ecological security pattern (ESP) urgently necessary. However, existing studies often fail to systematically integrate future landscape ecological risk (LER) assessment with ESP optimization. This study evaluated regional LER using the “ecological patches–ecological resistance surface (ERS)–ecological corridor” framework, combined with land-use predictions under three development scenarios, and optimized the ESP by adjusting the ERS and extracting ecological corridors. The results indicate that the LER in the WRB follows an “inverted N” distribution, with low-risk areas concentrated in forested mountain regions and high-risk areas mainly in cultivated land subject to intensive human activity. Across future scenarios, ESPs showed fewer ecological breakpoints and improved landscape connectivity than the 2020 baseline. Scenario-based differences emerged in the spatial configuration of ERS adjustments, with the ecological protection scenario yielding the lowest LER and most favorable ESP. This study demonstrates the deep integration of multi-scenario simulation with LER assessment, providing a new framework for ESP optimization. The findings have guiding significance for ecological protection and coordinated development in the WRB and offer a novel paradigm for sustainable development in ecologically fragile basins worldwide.</div></div>","PeriodicalId":45743,"journal":{"name":"Chinese Journal of Population Resources and Environment","volume":"24 1","pages":"Pages 94-109"},"PeriodicalIF":4.8,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147636803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how standardization promotes IGG by coordinating economic growth, environmental performance, and social equity remains insufficiently explored in the existing literature.

The analysis further explores the mediating roles of technological innovation, green finance, and employment quality, and examines heterogeneity across geographic location, resource endowment, industrial base, and city hierarchy. It also evaluates the regional coordination effects of standardization. Results show that standardization significantly advances IGG, though its impact varies by regional and structural characteristics. Standardization enhances IGG by strengthening innovation, expanding green finance, and improving job quality. Moreover, it helps bridge geographic divides, narrow interregional disparities, and enhance coordination.

The results show separating household waste significantly enhances consumers’ water-saving efforts. Both self-efficacy and ego depletion partially mediate the relationship between household waste separation and efforts to reduce water consumption. Specifically, if consumers engage in pro-environmental behaviors based on their internal, rather than external sense of moral identity, their sense of self-efficacy increases after separating household, which motivates them to engage in subsequent water-saving behaviors. In addition, consumers’ sense of ego depletion declines when they engage in household waste separation, which increases subsequent water-saving behavior. Compared to low-level self-determination needs, high-level self-determination needs weaken the positive impact of household waste separation on consumers’ perceived self-efficacy, but strengthens the negative impact of household waste separation on consumers’ perceived ego depletion and promotes subsequent water-saving behavior.

It also proposes reduction pathways to help China achieve its 2060 carbon neutrality goal. Animal and plant foods are categorized into 14 groups based on the similarity of their emission coefficients. China’s total food-related GHG emissions rose tenfold, from 351.7 to 3 719.8 million tons CO₂-equivalent (CO₂e)/year, between 1961 and 2020. Per-capita emissions increased from 532.1 to 2 584.4 kg CO₂e/year. Emissions from plant-based foods grew from 435.0 to 824.6 kg CO₂e/year, while animal-based emissions surged from 97.1 to 1 759.8 kg CO₂e/year, with animal products contributing more owing to their higher emission coefficients. Key drivers include rising food intake, increasing demand for animal-based foods (especially red meat), and population growth. Scenario analyses predict that emissions will peak at 3 826.2 million tons CO₂e/year in 2031 (low economy-low population) and 3 971.0 million tons CO₂e/year in 2039 (high economy-medium population).
