Investigating the influence of land use and socio-economic indicators on these emissions is crucial for achieving sustainable development goals. Existing research faces challenges such as focusing on specific regions, mixing variables that may exhibit multicollinearity, and lacking sufficient land use information. This study takes China, the largest emitting country, as a case study, utilizing geospatial big data to subdivide land use into 11 categories based on emission sectors. The impacts of land use and socio-economic indicators on different emission sectors are discussed from the perspectives of bivariate and spatial statistical analysis, with spatial hotspots identified. Hierarchical regression is used to evaluate the explanatory power of the indicators and to establish models, and potential carbon reduction strategies are further explored. Key findings reveal: (1) Significant multicollinearity between land use and socio-economic indicators was demonstrated, with land use explaining 57.1 % of emissions compared to 37.4 % explained by socio-economic indicators. The spatial consistency between land use and emissions exceeds 80 %, and the spatiotemporal variability is relatively low, making land use a more advantageous factor in explaining point source carbon emissions. (2) Agricultural mechanization increases emission intensity, but this efficient farming method helps convert surplus plowland, the largest influencing factor (Coefficient = 0.717), into carbon sinks, thereby controlling agricultural emissions. (3) Land intensification helps control the area of industrial land, the main factor influencing industrial emissions (Coefficient = 0.392). It also contributes to the efficient use of carbon reduction technologies and industrial supporting land. (4) Mixed commercial and residential land has the greatest impact on commercial, service, and household emissions. However, its relationship with the economy (Correlation = 0.479) is stronger than its relationship with emissions (Correlation = 0.182), making it more applicable to cities that serve as economic growth hubs.</p>","PeriodicalId":422,"journal":{"name":"Science of the Total Environment","volume":" ","pages":"176500"},"PeriodicalIF":8.2,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142338580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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, exogenous acids (HNO₃ and H₂SO₄) are also involved in carbonate weathering, complicating the overestimation of the formation of carbon sinks and fluxes. In this study, we analyzed the Hongjiadu karst underground river basin in Guizhou using isotopes (δ¹³C-DIC, δ³⁴S-SO₄, δ¹⁸O-SO₄, δ¹⁸O-H₂O, and δ²H-H₂O) and hydrochemical methods to investigate carbon cycling characteristics and its influencing factors, and quantitatively evaluate the effects of HNO₃ + H₂SO₄ on CO₂ sink fluxes in the basin. The following results were obtained: (1) The nitrate in the watershed mainly comes from fertilizers, and the sulfate mainly comes from local coal seams. (2) The relationship between isotopes (δ¹³C-DIC, δ³⁴S-SO₄, δ¹⁸O-SO₄, δ¹⁸O-H₂O, and δ²H-H₂O) and hydrochemicals (Ca²⁺, Mg²⁺, NO₃^-, HCO₃^-, and SO₄^2-) indicates that H₂CO₃, HNO₃, and H₂SO₄ are involved in carbonate rock dissolution. Most of the samples in the watershed, particularly the acid mine drainage water, were affected by acid rain and sulfide oxidation, resulting in increased δ¹³C-DIC values. Another portion of the springs was affected by soil CO₂, resulting in decreased δ¹³C-DIC values.

Rainfall enhances the weathering of carbonate rocks. In the process, CO₂ is released, increasing the carbon source.

OPEs are released from many sources, particularly, from the breakdown and weathering of plastic wastes, as OPEs are commonly used plastic additives.

While natural minerals often contain metal impurities, it is unclear how metal heteroatoms affect the efficiency of mineral nanoparticles in mediating hydrolysis reactions. Herein, we show that transition metal-doped anatase titanium dioxide (TiO₂) nanomaterials are more effective in catalyzing the hydrolysis of 4-nitrophenyl phosphate (pNPP), a model OPE compound, with the relative effects of the heteroatoms following the order of Fe > Cr > Mn ≈ Ni > Co > Cu. With multiple lines of evidence based on spectroscopic analysis, kinetics modeling, and theoretical calculations, we show that metal doping increases the Lewis acidity of the TiO₂ nanomaterials by increasing the oxidation state of surface Ti atoms, inducing oxygen vacancies, and creating additional Lewis acid sites with stronger acidities. Moreover, the increased amounts of surface hydroxyl groups due to metal doping enhance inner-sphere complexation of pNPP through ligand exchange.

However, accurately quantifying the sources of NO₃^- in aerosols remained questionable. In this study, we coupled dual isotopic composition of NO₃^- with multiple emission inventories during winter 2018 and summer 2019 to accurately identify the sources of NO₃^-. Source apportionment revealed that mobile sources (including road traffic and shipping) contributed 36.7 % to NO₃^-, followed by coal combustion (18.6 %), lightning (10.1 %), biomass burning (9.8 %), industry oil (8.8 %), natural gas (8.6 %), and soil (7.4 %) during summer.

However, we still have a limited understanding on how temporal variations of environmental factors (e.g., hydrological conditions) affect these flows. To address this gap, we investigated the effects drying has on cross-habitat subsidy flows and meta-ecosystem food webs by integrating both aquatic and terrestrial communities across the different hydrological phases (wet, contraction, and dry) in temporary saline lotic and lentic ecosystems. We analyzed the δ¹⁵N and δ¹³C signatures of aquatic and terrestrial basal subsidies, aquatic and terrestrial invertebrates, distinguishing between aquatic, riparian, shoreline and dry bed habitats. In the two temporary inland waters studied, drying of aquatic habitat and the subsequent expansion of the terrestrial habitat, significantly influenced cross-habitat subsidies and the meta-ecosystem food webs. In the wet and contraction phases, we found that the importance of aquatic subsidies in terrestrial food webs was constrained to terrestrial invertebrates near the aquatic habitat. Also, the contraction phase led to higher consumption of aquatic subsidies by aquatic and shoreline invertebrates, through a higher predation between aquatic invertebrates, and an enhanced accessibility of terrestrial invertebrates to aquatic subsidies. Whereas, riparian invertebrates showed prevalence for terrestrial subsidies throughout drying. Biofilm emerged as an important subsidy for both riparian and shoreline terrestrial invertebrates in the dry phase. In addition, the complexity of meta-ecosystem food web increased during drying, led by invertebrate diversity, omnivory and the type of temporary inland water. Our findings emphasize the significant impact drying has on cross-habitat subsidies and meta-ecosystem food webs, and the importance of integrating both aquatic and terrestrial communities in food web studies in temporary inland waters.

S1 radiometric data helped delineate water extents, while S2-Top of Atmosphere (TOA) multispectral data, corrected using the Modified Atmospheric correction for INland waters (MAIN), used to estimate turbidity levels. To ensure a comprehensive time series of RS data, we utilized S2-TOA data corrected with the MAIN algorithm rather than S2-Bottom Of Atmosphere (BOA) data. We validated the MAIN algorithm's accuracy against GLORIA (Global Observatory of Lake Responses to Interventions and Drivers) observations of surface water reflectance in lakes, globally. Subsequently, the corrected S2 data is used to calculate turbidity using the Novoa and Nechad retrieval algorithms and compared with GLORIA turbidity observations. Findings indicate that the MAIN algorithm adequately estimates water-leaving surface reflectance (Pearson correlation > 0.7 for wavelengths between 490 and 705 nm) and turbidity (Pearson correlation > 0.6 for both algorithms), determining Nechad as the more effective algorithm. In this regard, we used S2 corrected images with MIAN to estimate turbidity in the study area and evaluated with local gauge data and observational reports. Results indicate that the proposed framework effectively captures trends and patterns of turbidity variation in the study area.
