It also explores differentiation driving forces using Geodetector Geographically Weighted Regression. The results indicate that: 1) for area is 30 m × m, extent 200 m. 2) Compared 1990s, past two decades have seen an increased degree fragmentation, higher isolation, stronger human disturbance area, with significant differentiation. These changes are most pronounced semi-urbanized along river northern regions. 3) Digital Elevation Model land cover type critical factors. Over time, explanatory power factors shows overall increasing trend. 4) There a spatial heterogeneity forces. influence slope north south, weaker central region, while temperature increases south. impact periphery.

Introduction Ecosystem services (ESs) assessment plays a significant role in managing ecological resources. From the perspective of land use, this research aims to uncover complex interdependence between ESs and their key drivers clarify optimize function zoning region. Methods This focuses on Henan Province China, quantifying five ESs, namely, carbon storage (CS), habitat quality (HQ), soil conservation (SC), water (WC), yield (WY), assessing interactions from 2000 2020 2035. Moreover, study explores social - driving factors influencing these ESs. Finally, it classifies types ecosystem service bundles (ESBs). Results (1) 2020, use evolution was characterized by large expansion construction land, continuous decrease cultivated area, relatively stable changes other types. In protection (EP) scenario 2035, area decreased most, forest increased slightly. CS HQ showed trend degradation, while SC, WY, WC first fluctuated then increased. (2) The synergistic relationship each main one, among which WC-WY, CS-HQ HQ-SC relationships, CS-WC HQ-WC change trade-off relationship, were mainly relationships. Meanwhile, most B4 central part region dominated, rest volatility. (3) Elevation slope are dominant restricting spatiotemporal distribution CS, HQ, SC. Temperature precipitation primary conditions affecting differentiation WY WC. interaction topographic climatic has greater impact than single factor.

With the acceleration of urbanization, ecosystem around cities is facing severe challenges. The drastic changes in landscape pattern, especially urban–suburban areas, are usually regarded as one main drivers. However, spatiotemporal heterogeneous impacts patterns on services this region remain unclear. To address issue, we propose a novel framework integrating InVEST-based service assessment and weighted regression (STWR)-based analysis heterogeneity apply it to empirical study Fuzhou City from 2000 2020. It first utilized InVEST model build comprehensive index (CES) five aspects (i.e., habitat quality, carbon storage, water yield, soil retention, purification capacity). Then, four pattern indices (LPIs) patch density (PD), area-weighted mean fractal dimension (FRAC_AM), splitting (SPLIT), Shannon’s diversity (SHDI) index) were selected STWR model. We compared analyzed differences spatial coefficient surfaces significance tests generated by urban, urban–suburban, rural areas. Results show that following: (1) CES shows an upward trend urban area with significant gradient differences. (2) Compared other LPIs areas more fragmentation, discreteness, diversity, indicating socioeconomic activities. (3) Although LPIs’ change over time (increasing 2005 2010 2020 but decreasing 2015), their effects relatively low significantly lower than (4) Interestingly, LPI coefficients near boundary seem significant. (5) This can effectively reveal relationships between various CES, thus guiding concrete policies measures support decision-making for improving surrounding through shaping patterns.

Abstract The variations in soil erosion significantly impact regional ecological security. Under rapid urbanisation, extensive restoration and climate change, development the red region of southern China is ambiguous. Therefore, this study investigated current (1980s–2020) future (2050) characteristics a typical control catchment (Changting section catchment) by using Cellular Automata Markov model CMIP6 data to predict scenarios Revised Universal Soil Loss Equation estimate erosion. results showed significant changes vegetation coverage major land uses from 1980s 2020, which was mainly caused continuous water conservation (SWC). use subtypes that were obtained reclassifying based on threshold cover control, reflect transformation those with poor SWC effectiveness great effectiveness. estimated intensity continued decrease contribution use/land (LULC) impacts ranged 74%–195%. However, predictions indicated LULC may be stable after 2020; thus, changed little when almost unchanged 2050. change scenarios, increase 111%–121%, precipitation 63%–66%. driving factor shift 2020. future, potential for reducing limited, more engineering measures should applied address risk changes.

Maintaining a supply–demand balance of ecosystem services (ES) is essential for enhancing the effectiveness restoration. However, inappropriate land use and reforestation practices can negatively impact this balance. In study, ES Saihanba region in China was quantified by integrating use/cover change (LUCC) data, landscape metrics, indicators. The relationship between its driving factors analyzed using spatial panel models. spatiotemporal changes patterns from 2002 to 2020 were also explored. results indicated that overall supply capacity study region, especially southwestern area, increased during research period. determining exhibited significant heterogeneity spillover effects. Large–scale afforestation local provided economic benefits, but it led ecological issues, including declines wetland area fragmentation. Our emphasized importance considering planning decision–making ES, providing insight into multifunctional management sustainable development area.
