Establishing effective ecological restoration strategies to enhance soil anti-erodibility on these exposed steep slopes represents a critical challenge in semi-arid environments. This study investigates the restoration benefit and anti-erodibility of Gramineae-Legumes mixed planting through spray-seeding techniques on artificial substrates, using natural slopes as controls. Results showed that the Gramineae-Legumes mixed grassland reduced the temperature and humidity of the steep slopes, but quickly reconstructed the area's vegetation, decreased the soil porosity and saturated hydraulic conductivity, and increased the soil density and compactness. Compared with the natural slope, the soil anti-erodibility of sunny slopes and shady slopes increased by 31.29 % and 47.44 % after restoration, respectively. The spray-seeding of Gramineae-Legumes mixtures effectively improves soil structure and accelerates vegetation community reconstruction on loess steep slopes. This approach reduces soil pore connectivity and water permeability while enhancing anti-erodibility and ecological benefits, particularly in semi-arid environments. The integrated approach of spray-seeding Gramineae-Legumes mixtures combines vegetation restoration and slope stabilization technologies, demonstrating a dual-benefit solution for addressing geological safety and ecological sustainability in fragile semi-arid environment.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"126489"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Green credit policy (GCP) is considered an important financial policy tool to promote green and sustainable development, but government intervention may also bring about resource misallocation. By constructing a theoretical model of enterprise production function from the perspective of excess capacity, combined with the data of listed enterprises from 2008 to 2023 and the empirical test of the difference in difference (DID) model, this paper studies whether GCP will lead to non-green behaviors in ECIs. The results show that: (1) The GCP will cause enterprises to increase their holdings of speculative financial assets and the degree of greenwashing. (2) GCP increases financing constraints, guides financing methods from traditional credit to financial loans, and promotes capital liquidity risk and debt repayment pressure as the main channels. (3) Strengthening financial supervision and popularizing the application of blockchain technology are important measures to alleviate enterprises' non-green behaviors. (4) The impact of GCP is more significant in the metal industry, the chemical industry, growing enterprises, and regions with low marketization degrees. The research in this paper has enriched the investigation of non-green behaviors of enterprises under GCP, filled the gap of existing studies, provided new evidence for curbing enterprises from real to virtual and alleviating greenwashing behaviors, and policy reference for promoting the development of GCP and promoting the low-carbon transformation of ECIs.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"126534"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

It summarizes the results of more than a decade of research conducted in a lowland river (the Upa River) basin heavily contaminated after the Chernobyl accident. The overbank deposition of sediment-associated ¹³⁷Cs on floodplains is determined by several factors, which must be considered when interpreting the observed contamination patterns, the most important being topography and hydrological regime, which control frequency of floodplain inundation during high water periods. Frequent floodings are conducive to a better record of ¹³⁷Cs variations in sediment load. The ¹³⁷Cs vertical distribution in floodplain sediments can be altered by certain disturbances, which makes its interpretation more difficult. The contribution of local sources to sediment load should be considered to avoid misinterpretation of ¹³⁷Cs redistribution in upstream catchment. Downstream overbank deposition is impacted by management of river flow through artificial reservoirs, and therefore such floodplain sediments do not represent migration of ¹³⁷Cs in upstream catchment. Nevertheless, investigation of floodplains downstream can provide valuable data about transport of clay and silt particles carrying pollutants.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"126558"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144641405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Efficient hydrolysis of lignocellulose, as well as complete oxidation of hydrolysis products is critical for heat production during aerobic fermentation of lignocellulosic biomass. This study systematically demonstrates that Fe₂O₃ nanoparticles (NPs) enhance heat production in lignocellulose bio-oxidation during corn stover fermentation through synergistic effects between reactive oxygen species (ROS) generation and microbial community restructuring, thereby optimizing fermentation efficiency and shortening fermentation cycles. Specifically, Fe₂O₃ NPs facilitated Fenton-like redox cycling to generate ROS, thereby creating accessible enzymatic reaction sites and accelerating lignocellulose degradation. Additionally, ROS-induced oxidative stress triggered microbial metabolic flux redistribution, directing more glucose toward catabolic pathways to sustain cellular metabolism, thereby improving glucose oxidation efficiency and associated heat output. Results showed that Fe₂O₃ NPs enhanced organic matter degradation by maintaining a high abundance of Bacillota, thereby optimizing the functionality of microbial community. In presence of Fe₂O₃ NPs, cellulose degradation rate reached 42.53 % within 30 days, representing a 13.60 % increase compared to the control group (CK). Furthermore, Fe₂O₃ NPs treatment achieved a peak heat production rate of 2.25 W/kg, which was 15.38 % higher than CK. Compared with Fe₂O₃ NPs, Fe₂O₃ submicron particles were less efficient in synergizing with microorganisms due to their restricted specific surface area, which resulted in a lower heat production rate. These findings highlight the potential of incorporating Fe₂O₃ NPs into agricultural waste aerobic fermentation systems as a viable strategy to enhance resource utilization efficiency.</p>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"391 ","pages":"126577"},"PeriodicalIF":8.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Consequently, a variety of management approaches, such as the provision of winter feeding, have been deployed to keep deer from foraging in undesired areas in an attempt to mitigate conflicts. However, as large ungulates play a key role in nutrient recycling and redistribution, management actions that affect their space use and introduce additional nutrients into a system may translate into changes in the biogeochemistry of protected areas. Yet, little is known about the implications of such deer-management strategies on nutrient patterns. Here, we tested the effects of intensive supplementary feeding in combination with winter enclosures on nutrient distribution in a strictly protected area in Central Europe, the Bavarian Forest National Park. We found significant effects of the current management approach on plant nutrients with elevated nutrient concentrations not only within, but, importantly, extending up to several hundred meters around the enclosures/feeding stations. The increased nutrient concentrations could have cascading consequences for soil microbial activity, plant community composition and other herbivores.

However, accounting for biodiversity, particularly at smaller site-specific scales, is underdeveloped in the SEEA-EA.
