However, limited data are available regarding the relationship between landscape metrics and soil ecological functions. In this study, using 99 National Forest Villages (NFVs) in the middle and lower reaches of the Yellow River Basin as study objects, landscape metrics were computed for circular areas of ten extents in FRAGSTATS. Differences in soil carbon (C), nitrogen (N), phosphorus (P), physicochemical properties, and landscape metrics between the middle and lower reaches were compared using a one-way ANOVA. Multiscale performance of 14 forest landscape metrics as indicators of 10 soil parameters was explored using several methods: partial correlation, linear mixed model, linear mixed-effects model, and threshold model. The results showed that NFVs in the middle reaches had higher soil C and N and better physicochemical properties, but lower soil P than the lower reaches. The landscape pattern showed large variations between the middle and lower reaches. Soil C and N were positively correlated with patch number and shape metrics, respectively, before the threshold. Soil P and physicochemical properties were negatively correlated with forest area metrics before and after the threshold. The correlation between landscape metrics and soil parameters depended on kilometer scale. Our findings highlight that soil characteristics and forest landscape patterns of National Forest Villages are linked, and landscape regulation can improve forest soil C and N, as well as the physicochemical properties. The insights from this study are vital for informing land management decisions aimed at enhancing carbon sequestration, mitigating climate change, and maintaining soil fertility. Ultimately, this research provides a reference for other river basins and landscapes, and future research should consider human activities at larger kilometer scales to predict soil properties.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"173 ","pages":"Article 113391"},"PeriodicalIF":7.0,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715072","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}

To construct the river integrated ecosystem health index (R-IEHI), we first selected multiple biological group indicators, including commonly used evaluation groups such as fish, macrobenthos, and phytoplankton.

We then combined this with several other group-specific indices to create a simplified comprehensive evaluation index. The calculation of the R-IEHI score involves first normalizing each individual index, followed by a weighted summation. Both the sample-based and river segment-based indices can significantly distinguish different levels of disturbance intensity. However, since rivers are continuous systems, the river segment-based evaluation index is better suited for assessing the health of small watersheds.

By integrating remote sensing inversion, GIS spatial analysis, and the constraint line model, the following key findings were obtained: (1) Spatiotemporal Evolution Characteristics: From 2000 to 2023, the FVC in the study area exhibited a fluctuating upward trend (annual growth rate of 0.26 %, <em>R</em><sup>2</sup> = 0.5654, <em>p</em> &lt; 0.001), forming a significant longitudinal gradient pattern. A sharp contrast was observed between the high-coverage areas (FVC &gt; 60 %) in the southeast and the lowcoverage areas in the northwest, where bare land and extremely low to low-coverage regions accounted for 56.25 %. Notably, 54.84 % of the region experienced significant vegetation improvement, with the “greening” effect particularly pronounced in the central and western regions. (2) Topographic Vertical Constraint Mechanism: The altitudinal gradient shaped a four-stage response pattern: in the 2000–2900 m range, vegetation cover increased at a rate of + 1.56 %/100 m, mainly driven by water-heat synergy; in the 2900–4000 m range, accumulated environmental stress reversed the growth trend, leading to a decline of −1.32 %/100 m; in the 4000–4800 m range, thermal constraints intensified sharply, accelerating the decline to −8.01 %/100 m; in the 4800–5800 m range, vegetation approached its survival limit, with the decline rate slowing to −0.57 %/100 m. (3) Climatic Regulation Threshold Effects: Temperature control exhibited a biphasic hump-shaped pattern (<em>R</em><sup>2</sup> = 0.9449). In the −15 °C to −7°C range, the FVC gain rate reached 14.22 %/°C; between −7°C and 0 °C, the gain rate decreased to 3.07 %/°C, with 0 °C identified as a critical threshold. Above 0 °C, increasing competition pressure led to a decline in FVC (−0.68 %/°C). Moisture regulation showed a diminishing marginal effect: in the 20–300 mm range, each additional 10 mm of precipitation increased FVC by 2.97 %; in the 300–450 mm range, the marginal gain decreased to 0.88 %; above 450 mm, moisture constraints were lifted, and light-heat conditions became the primary limiting factors. This study identifies critical ecological thresholds of 4000 m altitude, an annual mean temperature of 0 °C, and 300 mm annual precipitation, elucidating the nonlinear response mechanisms of mountain ecosystems. Furthermore, it establishes a multidimensional “topography-climate-management” adaptive regulation framework, providing a scientific paradigm for transitioning ecological restoration from “maximum greenness” to “optimal resilience.”</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"173 ","pages":"Article 113328"},"PeriodicalIF":7.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705350","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}

Using the Carnegie-Ames Stanford Approach (CASA) model and the carbon emission coefficient method, the supply and demand of carbon sequestration services from 2000 to 2020 were quantitatively assessed. The supply–demand ratio index (SDI) and Local Indicators of Spatial Association (LISA) were employed to analyze the spatial distribution and intensity of the supply–demand relationship. The results reveal that while the supply of carbon sequestration services exhibited an overall increasing trend, demand steadily grew, leading to a widening mismatch, particularly in the economically developed eastern regions and urban agglomerations. The supply was primarily influenced by the Normalized Difference Vegetation Index (NDVI) and land use/land cover change (LUCC), while demand was closely linked to population density (POP) and Gross Domestic Product (GDP). To further analyze the factors driving this mismatch, the Structural Equation Model (SEM) and Random Forest (RF) model were applied to identify the impact of both natural and human activity factors. SEM highlighted complex causal relationships, while RF captured nonlinear interactions between these variables. The findings emphasize the growing tension between insufficient supply and rising demand for carbon sequestration services in key regions. To mitigate this spatial mismatch and support the “dual carbon” goals, several policy recommendations are proposed, including strengthening ecosystem protection, promoting sustainable land management practices, establishing carbon markets, and encouraging broader participation in carbon trading.

However, existing research has paid limited attention to the long-term spatiotemporal evolution of carbon budgets at fine scales, often overlooking comparative differences in natural resource endowments and socio-economic conditions across regions. To address this gap, we developed a “carbon source- carbon sequestration ” quantification model using multi-source data and employed a hierarchical analysis approach to examine carbon budget inequities in the Yangtze River Delta (YRD) region at both grid and county scales. A multidimensional evaluation system was constructed to elucidate the interactions among key indicators, and compensation zoning types were refined based on functional zone positioning. The results reveal that: (1) At the grid scale, carbon emissions transitioned from point-like to patchy agglomeration, while carbon sequestration expanded outward from major mountain ranges, forming multi-scale sequestration surfaces. At the county scale, carbon emissions exhibited a “core-periphery” structure, with carbon sequestration showing a “high in the south, low in the north” spatial heterogeneity. (2) The carbon budget characteristics of functional zones aligned with their designated roles, with greater variability in the concentration index of carbon emissions compared to sequestration. (3) Scale background attributes (SBA) and socio-economic attributes (SEA) exhibited a nonlinear negative correlation, while spatial structure attributes (SSA) positively influenced ecological environment attributes (EEA), particularly in Optimized Development Zones (ODZ). (4) Based on the spatial comparative advantages of attribute indicators, 120 payment zones, 95 balancing zones, and 90 compensation zones were identified, further refined into 10 distinct carbon compensation zoning types integrated with major functional zones. This study provides a more equitable framework for cross-regional carbon compensation through fine-scale analysis and functional zone perspectives, offering scientific support for collaborative emission reduction efforts.</div></div>","PeriodicalId":11459,"journal":{"name":"Ecological Indicators","volume":"173 ","pages":"Article 113383"},"PeriodicalIF":7.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705356","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}
