Synergies and trade-offs among land use covers (LULCs) pose considerable uncertainties in achieving the dual carbon goals for China's Loess Plateau (CLP). In this context, we unraveled stock dynamics induced by cover change (LUCC) CLP over past 40 years using satellite-derived annual LULC maps InVEST model. Then, mixed measures were employed to quantify global local responses of both natural anthropogenic factors. We found that approximately a total 5.58 × 109 Mg was stored CLP's ecosystems 2019. Chronologically, showed slight decrease from 1980 2019 due extensive LUCCs linked socioeconomic activities. Specifically, density loss rate accelerated urban–rural-wild continuum (RUWC) types with higher human activity intensity, such as villages urban, while it decelerated woodlands, croplands, where intensity is lower. Moreover, gain wildlands accelerating. Finally, revealed primarily influenced variables have responded diversely drivers space.

Faced with increasingly severe climate change, assessing integrated effects of Land use and land cover (LULC) changes on carbon metabolism contributes to the understanding mechanism LULC‑carbon interactions is crucial enhance benefits anthropogenic emission reductions, increasing regional sinks formulating future mitigation policies. In this paper, we have developed a hybrid analytical framework that couples natural socioeconomic systems, used data, high-resolution remote sensing empirical coefficients analyze spatiotemporal dynamics applied ecological network analysis (ENA) evaluate LULC upon metabolism. We Gansu Province, an economically underdeveloped region, as example for case policy recommendations. The results showed that: (1) total emissions in increased 3.18 times between 1995 2020, transportation industrial being major contributors. balance status was severe, amount sequestration offset decreased from 22.45% 7.11% 2020. (2) ENA revealed competition relations types fluctuated up dominated mean value mutualism index 0.72, which suggested whole negative. Compared regions, relationships different were more competitive. (3) To address these issues, proposed comprehensive policies terms adjusting structure, reducing fossil energy use, saving construction, developing sink industries. study explored intricate changes, transition, its findings provide insights recommendations spatial planning management Province other regions may comparable challenges.

The ecological security pattern construction could effectively regulate processes and ensure functions, then rationally allocate natural resources green infrastructure, and, finally, realize security. In view of serious soil erosion, accelerated land desertification, pollution habitat degradation in Shanxi Province, the spatial distribution six key ecosystem services, including water conservation (WC), (SC), sand fixation (SF), carbon storage (CS), net primary productivity (NPP) quality (HQ), was analyzed by using multiple models. comprehensive ability services different regions quantified calculating landscape index (MESLI). Combined with hotspots, Province constructed minimum cumulative resistance model. results showed that differences were obvious, which low seven major basins Fen River valley, high mountains (especially Taihang Lvliang Mountains) for WC, SC, CS, NPP HQ, while SF only distributed northern Shanxi. MESLI to provide simultaneously medium grade accounting 58.61%, 18.07% regions. important protected areas sources concentrated Mountains, consistent services. corridors illustrated network as center, low-, medium- high-level buffers accounted 26.34%, 17.03% 16.35%, respectively. will implications economic transformation, high-quality development sustainable resource-based worldwide.

The alteration of land use and cover (LULC) the landscape ecological risk index (LERI) significantly impact carbon storage. Examining storage services in ecologically significant places is crucial for achieving a harmonious relationship between economic development region, conservation terrestrial ecosystems, mitigation sink depletion. This study aims to provide complete framework that integrates PLUS, Fragstats, InVEST models. will be utilized optimize LULC LERI, specifically maximizing analysis carried out over an extended duration from various viewpoints. results indicate MJRB ecosystem experienced three clearly defined phases: enhancement (1985–1995), degradation (1995–2010), subsequent (2010–2020). LERI high-level patterns showed similar trends. local ecosystems can primarily due widespread caused by socio-economic development. Ecological Preservation Scenario projected increase 41.97 Tg 115.18 In contrast, urban scenario substantial decrease rates, namely 0.89% 1.34%, evident Chengdu zone. An coupling coordination revealed negative high while positive connection was observed with low LERI. established rapidly assessing forecasting trajectory It aids optimizing patterns, conserving areas sequestration, ensuring establishment high-quality ecosystems. serves as guide regional “dual carbon” objectives.

Evaluation of Ecosystem Service Capacity Using the Integrated Ecosystem Services Index at Optimal Scale in Central Yunnan, China

Ecology and Evolution, Год журнала: 2025, Номер 15(4)

Опубликована: Апрель 1, 2025

Understanding and quantifying the dynamic features of local ecosystem services (ESs) integrating diverse assessment results form crucial foundations for regional ES management. However, existing methods objectively evaluating multiple ESs remain limited. Consequently, this research evaluates four key based on InVEST RUSLE models in Central Yunnan Province (CYP)-from 2000 to 2020: water yield (WY), carbon storage (CS), habitat quality (HQ), soil conservation (SC). It then constructs an Integrated Ecosystem Service Index (IESI) using principal component analysis (PCA). Additionally, study explores factors driving spatial divergence by employing optimal parameter-based geographical detector model (OPGD) at scale. The indicated that (1) IESI was effectively applied CYP could quantitatively comprehensively integrate ESs. (2) During period, showed increasing trends WY, HQ, SC, while CS a decreasing trend. (3) during period exhibited trend initially increasing. average values were 0.7338 2000, 0.6981 2005, 0.6947 2010, 0.6650 2015, 0.6992 2020. (4) A 4500 m × grid identified as scale detecting comprehensive service (CES) CYP, relief degree land surface (RDLS), slope, NDVI top three drivers q-values. This offers more scientific effective method CES. also provides analytical tool balancing use competition assessing effectiveness policy implementation.
