This study utilizes bird observation data collected from a citizen science platform in Nanjing, China, to explore the spatial scales most appropriate for assessing urban bird diversity (species richness and functional diversity) and their non-linear associations with various landscape features. Advanced machine learning models, such as Boosted Regression Trees (BRT), eXtreme Gradient Boosting (XGBoost), and SHapley Additive exPlanations (SHAP), were employed to analyze these relationships. Key findings include: (1) A sum of 275 bird species were recorded in Nanjing's main urban area, with <em>Passeriformes</em> (77.06 %) being the dominant order. Both indices increased in average value as the scale size expanded (300 m, 500 m, 700 m, 900 m, 1100 m, 1300 m, and 1500 m). Statistical analysis indicated a more random spatial distribution of bird richness at smaller scales (300–700 m, Moran's <em>I</em> = 0.24), while functional diversity remained largely stable across scales. (2) The BRT results indicated that the relationship between bird diversity indices and landscape features peaked at the 900 m scale, which was thus identified as the optimal spatial scale. (3) Excessive nighttime lighting (values >62), high building density (> 0.15), and road density (> 5) were found to suppress bird diversity, while favorable terrain conditions, such as moderate elevation (50–150 m), aspect angles (100°–200°), and gentle slopes (< 5°), along with enhanced ecological conditions (RSEI >0.5) promoted it. Interaction analyses further demonstrated that the effects of terrain variables, building density, and road density attenuated the negative impacts of urban nighttime lighting. These findings offer practical implications for urban planning and design by identifying scale-sensitive and threshold-based strategies to support bird biodiversity and promote harmonious coexistence between humans and nature in metropolitan landscapes.</div></div>","PeriodicalId":309,"journal":{"name":"Environmental Impact Assessment Review","volume":"115 ","pages":"Article 108029"},"PeriodicalIF":9.8,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144205286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The QRF prediction model achieved acceptable accuracy, with an R<sup>2</sup> of 0.485. Spatially, the distribution pattern of the <em>K</em> factor from 1980 to 2100 remained relatively consistent, with higher values in the central-eastern, northeastern regions, and lower values in the northwestern, southern regions. Historically, a decreasing trend was observed in the <em>K</em> factor between the 1980s and 2010s.

It utilizes the stochastic impacts by regression on population, affluence, and technology (STIRPAT) model and planning models to develop the lowest-cost allocation scheme for pollution and carbon emission reduction based on the reduction targets for the YRD city cluster. The results indicate the following. (1) The integrated air pollutant emissions in the YRD city cluster exhibit a fluctuating upward trend, with population size having the greatest impact.

Although the use of the maturity indicator causes an allocation of more emission reduction tasks to cities in the high maturity group, most cities in the low maturity group require a larger proportion of emission reductions.

As the world's largest carbon emitter and a member of the Parties of the Paris Agreement, China plays a vital role in reducing and neutralizing greenhouse gases emissions. To demonstrate the determined attitude and progressive actions to confront global warming, in China, 17 pilot Policy EIA cases were initiated from 2021 to 2023, where CC considerations are required to be integrated into Policy EIA. Adapted from the best available international practices, 22 focusing and streamlined criteria covering CC mitigation and adaptation are assembled to prudentially scrutinize CC considerations in these pilot cases. In addition, direct content analysis is applied to identify and analyze text references related to the evaluation criteria, and correlation analysis is employed to refine and validate the research findings. Overall, the results indicate that while climatic factors are considered to some extent, the integration of CC considerations into Policy EIA is in an unsatisfactory manner, with dissimilar performance across different subjects and categories. Besides, much more effort was put into mitigation consideration than into adaptation consideration. Moreover, there is a lack of applicable quantitative methodologies to measure CC impacts, while the absence of accessible, robust, and quality-assured data has become a major obstacle to CC assessment. Correspondingly, some recommendations are proposed to further improve the integration of CC considerations into Policy EIA.
