However, most traditional studies either fail to incorporate ecosystem service flows or lack a systematic model that captures the entire process of ecosystem service supply, transmission, and response. This limitation reduces the spatial accuracy of identification and weakens the coordination of ecological functions. Therefore, taking the middle reaches of the Yangtze River as a case, this study constructs a dynamic supply‒demand balance framework on the basis of service flows. By integrating a process‒oriented flow allocation model and a coupled coordination model, the framework evaluates the dynamic supply‒demand relationship and establishes a comprehensive importance index for ecological protection, combining service supply capacity, supply‒demand matching, and coordination level. Priority areas are identified under different scenarios, and their scientific validity and applicability are verified through cost‒benefit ratio analysis. The results revealed that: (1) flood regulation services are dominated by inter‒city flows, with 72.58 % of paths and 75.71 % of volume, while outdoor recreation and thermal environment regulation services mainly flow within cities, with paths reaching 89.45 % and 97.63 % and flows 93.14 % and 98.9 %. Except for thermal environment regulation service, capital cities show demand spillovers. Additionally, all services display a supply pattern characterized by high values in peripheral regions and low values in central areas. (2) Under the dynamic perspective, the above‒mentioned demand spillovers help narrow spatial supply‒demand gaps and mitigate mismatch levels. Nevertheless, imbalances remain pronounced: flood regulation exhibits the highest mismatch at 83.30 %, followed by thermal regulation at 76.70 %, and recreation at 34.27 %. (3) Under the dynamic supply‒demand balance scenario, 46.81 % of priority areas are green space and 3.56 % blue, covering key ecological areas such as Wuyi and Nanling mountains and Poyang and Dongting lakes. The proposed method integrates spatial flow analysis with supply‒demand matching, correcting approximately 17.78 % of ecological protection priority area delineations and thereby achieving the most favorable cost‒benefit trade‒off. By quantifying mismatches and explicitly identifying responsible entities for ecological protection, the approach enhances the operational feasibility of ecological space planning. It also provides a scalable toolset for implementing adaptive, region‒specific coordination strategies under the broader context of integrated regional development.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"520 ","pages":"Article 146023"},"PeriodicalIF":9.7,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144523348","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}

The proposed methodology integrates multi-scale characteristics of geological structures with spatially varied parameter weighting schemes, achieving comprehensive simulation of groundwater flow field variations induced by coal mining activities through systematic coupling of numerical modeling and decision support systems.

Hydrogeological analysis reveals the marked superiority of coarse-grained sandstones in enhancing aquifer water storage capacity and hydraulic conductivity, with their permeability-enhancing effects progressively diminishing as particle size reduces. The established variable weight set pair-connection cloud model significantly enhances analytical accuracy in multi-scale coupled zoning, enabling effective parameter partitioning for both Zhiluo and Yan'an Formations. The constructed simulation model successfully replicates aquifer flow field evolution during mining disturbances, achieving over 90 % consistency between simulated and measured water levels across monitoring points.

The strain PSB-1 significantly increased the content of solubilized phosphorus (P) to promote the degradation of oil pollutants.

The production of organic acids, such as oxalic and lactic acids, peaked at 263.52 mg·L⁻¹ and 282.99 mg·L⁻¹, respectively, indicating a potential enhancement of P availability due to the crucial role of organic acids in the process of P solubilization. The analysis of the degradation pathway of hydrocarbons and the content of alkaline phosphatase (AKP) under organic P deficiency indicated that pyruvate served as an intermediate product connecting P solubilization and hydrocarbons degradation.

In this study we modeled the impact of three surface water abstraction rates in the epilimnion for drinking water purposes in combination with climate change on the ecological quality and the recreational potential of a quarry lake in The Netherlands. Our results show that the highest surface water abstraction rate (1.36 m³/s) - related to the estimated abstraction rate for 2040 - would substantially change the ecological quality of the lake. Specifically, this surface water abstraction rate caused a threefold extension of the period of hypoxia in the hypolimnion and a reduction of the phytoplankton summer bloom as compared to the baseline. Simultaneously, the reduction of cyanobacteria in the lake due to the surface water abstraction would improve the lake's suitability for recreation, as the risk of harmful blooms becomes negligible. The two lower surface water abstraction rates showed results in between the no-abstraction and the high abstraction rate results. When considering only the changes in the climate between 2010 and 2050, we found that the lake's ecological quality would decrease, mainly due to prolonged hypoxic conditions. However, the recreational potential remained relatively unchanged due to climate change. Overall, our findings indicate that surface water abstraction, in particular at the highest rate, would have a more profound impact on the lake than the projected climate change.

This review finds that modified or combined NMs (called M/C NMs) can improve the photodegradation efficiency and maximum cycles of use of organic pollutants compared to Simple NMs through meta-analysis. Furthermore, this review also provides a comparison of Simple NMs and M/C NMs through meta-analysis to discuss their specific targets, effects of combinations or modifications, and the current challenges faced in the degradation of organic pollutants. This review highlights that M/C NMs can promote the absorption of organic pollutants and the excitation of photoelectrons due to improved band gaps, particle size, and structure, while requiring less stringent reaction conditions than Simple NMs. Even under visible light, M/C NMs can maintain higher degradation efficiency, achieving a 32.87 % reduction, compared to a 42.00 % reduction by Simple NMs. All NMs can achieve efficient photodegradation without the demand for an extreme pH environment or other common auxiliary substances, for example, H₂O₂.
