However, to what extent do the results depend on the methodological assumptions, and could a less stringent metric, allowing trade-offs between indicators, improve these outcomes? Preserving the core of Raworth’s theoretical framework, we address these questions by constructing two separate sets of composite indicators for the social and environmental dimensions. Following an uncertainty-based approach, we obtain the two sets by combining alternative normalisation, weighting, and aggregation techniques. This approach yields a new, easily communicable, and robust metric for the ‘safe and just space’.

Overall, ozone concentrations peaked at 50 ppb in summer, followed by spring (20 ppb) and autumn (21 ppb), with the lowest concentrations of 11 ppb observed in winter. The power sector was found to contribute the most to yearly ozone concentrations was about −12 to 9 ppb, followed by the residential sector, while the transportation and industrial sectors made the least contributions.

Ecological Water Conveyance (EWC) projects, by altering land use patterns, have become a key approach to addressing this issue. Therefore, the critical question this study aims to solve is how to enhance regional CS by optimizing EWC measures, based on understanding the relationship between land use changes and CS. To address this, we propose an integrated framework that couples the PLUS-InVEST-OPGD models, adopting a ’past-future’ perspective to explore the relationship between CS and land use changes in the context of EWC. The study found that during the historical period (2000–2020), CS in the Tarim River (TR) area exhibited a pattern of ’ first increasing, then stabilizing.’ Between 2000 and 2010, the total CS increased by 3.5 × 10^6 Mg, accompanied by an expansion of forested areas along the riverbanks and within national parks. However, from 2010 to 2020, the total CS increased by only 0.3 × 10^6 Mg, with forested areas along the riverbanks and within national parks remaining relatively stable. Under three future development scenarios—Natural Increase (NIS), Farmland Protection (FPS), and Ecological Protection (EPS)—CS differences between NIS and FPS are minimal at 0.01 × 10^6 Mg, as both continue existing EWC policies without optimization, with NIS following natural growth and FPS prioritizing farmland preservation. In contrast, the EPS, which introduces optimized EWC strategies to limit urban expansion and enhance ecological sustainability, results in a significant CS increase of approximately 1.1 × 10^6 Mg, with farmland areas also expanding. Through single factor and interactive detection analyses, we found that potential evapotranspiration and annual average groundwater depth play crucial roles in vegetation restoration in arid regions, as EWC helps maintain groundwater levels, reducing plant water stress and supporting vegetation growth, while managing evapotranspiration ensures that the water provided through EWC is efficiently utilized for ecosystem recovery and CS. Under the current EWC model and prevailing climate and human activity conditions, the CS capacity of ecosystems appears to stabilize. To further enhance the region’s CS potential, optimizing EWC strategies is essential. It is recommended to construct a ’surface’ water conveyance network through engineering measures, in addition to the existing ’linear conveyance’ model, to improve water resource utilization efficiency. The findings of this study offer valuable insights not only for the TR region but also for other arid inland river basins worldwide, providing a replicable framework for ecological restoration and water management.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"169 ","pages":"Article 112861"},"PeriodicalIF":7.0,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142706414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the first time, the SHI structure was investigated separately in the urban and non-urban areas and the permanent and seasonally specific SHIs were delineated. Seasonal variability was a significant feature of SHI structure, particularly in its non-urban part, which was driven mainly by the vegetation annual cycle and altitude-dependent snow cover distribution in winter. In the majority of seasons, the intense urban SHI was conventionally compacted in the central most urbanized part of the metropolis, and its area was changing in a pulse-wise manner throughout the year from the maximum in summer to the minimum in autumn. The extent of permanent urban SHI indicating areas risky for human health was larger than the extent of seasonally specific urban SHIs. It covered 3% of GZM and was mostly composed of industrial and commercial units. Permanent non-urban SHI was scattered throughout the GZM without any clear pattern and covered only 0.4% of the entire GZM, and 75% of its area was covered by non-irrigated arable land and pastures.

The challenge requires the urban spatial planning more sophisticated for developing eco-city models in the perspective of urban land multifunctionality. The Production-Living-Ecological(PLE) spatial pattern is proposed for effective eco-city planning in Chinese urban cases. Given the differing climatic and cultural contexts, are the PLE spatial patterns comparable between cities from different continents? This study aims to compare the characteristics of PLE spatial patterns and the trade-offs &amp; synergies of PLE spaces between Fuzhou city, China and Saskatoon, Canada for developing the eco-city models. First, the paper identified the PLE spaces by integrating multi-source data, then analyzed the PLE spatial agglomeration characteristics by using the average nearest neighbor and kernel density analysis, finally detected the trade-offs and synergies between functional spaces by Spearman correlation and bivariate spatial autocorrelation. The results showed the distinctly different PLE spatial patterns and the trade-offs &amp; synergies of PLE spaces between the two eco-cities in Fuzhou, China and Saskatoon, Canada in 2022. (1) For the PLE space composition, the percentages of ecological space in Fuzhou and Saskatoon were 64.6% and 36.4%, respectively, while the proportions of the most suitable residential space in two cities from POI data were 2.4% and 4.1%, respectively. (2) For PLE spatial agglomeration, ecological space in Fuzhou was characterized with a random distribution with the average nearest neighbor index of 1.19, and scattered as small patches in urban hilly area covered with ever-green broadleaf trees, while in Saskatoon the index was less than 1.00 with a clustered distribution in numerous city parks covered with grass and shrubs; Fuzhou’s multifunctional spaces were clustered in the central urban area surrounded by ring roads and in Changle District, while Saskatoon’s were dispersed with large patches. (3) For the trade-offs &amp; synergies of PLE space, the ecological spaces in two cities were suppressed. In Fuzhou, the trade-off area ratio of the ecological space to other fuctional spaces was ranged 50% to 58%, while in Saskatoon, it was 40% to 47%.

Spectral variability was positively correlated with fish diversity for all sensors, though the area in which the variability was computed (window size) was important. The strongest relationship between spectral variability and fish biodiversity (R = 0.48) was returned using UAV imagery corrected for surface artifacts via fluid lensing. Splitting fish into herbivores, corallivores, and piscivores revealed that different feeding strategies correlate to spectral variability at different scales.
