The quantitative evaluation and prediction of ecosystem service value (ESV) in the Lhasa River Basin can provide a basis for ecological environment assessment land-use optimization adjustment future. Previous studies on ESV have focused mainly static evolution analysis based historical data, not considered future development trends. Moreover, most current driving factors selected land use are homogeneous, do reflect geographical cultural characteristics study area well. With as research focus, 20 were according to plateau alpine area, changes under three developmental orientations, namely, natural evolution, protection, agricultural development, predicted year 2030 with FLUS-Markov model. Based these predictions, values services calculated, their spatiotemporal dynamic analyzed. results show that model has high accuracy simulating change Basin, kappa coefficient 0.989 an overall 99.33%, indicating applicability. types basin dominated by existence grassland, unused land, forest, combined proportion 94.3%. trends each type scenarios differ significantly, cropland, building showing significant changes. cropland increased only scenario; areas forest grassland protection expansion was effectively controlled scenario. all scenarios, spatial distribution per unit middle lower reaches greater than upper reaches. greatest scenario, grasslands, forests, water bodies contributing more basin. This provides decision-making references effective utilization resources, environmental planning, urban construction

Abstract Rapid global urbanization has perturbed ecosystem structures and functions, resulting in ecological risk threatening sustainable human well‐being socioeconomic development. However, scientific indicators to analyze service (ES) patterns need be explored detail. In addition, studies on ES supply are stagnating historical or status explorations, especially from the view of disturbance land‐use changes. This study seeks develop a framework for modeling past‐future pattern evaluation probing into under different future scenarios. To achieve this objective, integrates Future Land Use Simulation (FLUS) model, Intelligent Urban Ecosystem Management System (IUEMS) an established indicator system incorporating trend, hotspots coldspots, trade‐offs, synergies. The results show that: (1) 2050, climate regulation Xi'an Metropolitan Area (XMA) will increase, while that carbon sequestration recreation decrease. is highest protection (EP) scenario, cropland (CP) scenario.

The Qinghai-Xizang Plateau (QXP) in China is a geological treasure trove known for its complex structures and rich mineral resources. Among these, copper stands out as critical metal economic development. However, the exploitation of these resources not without challenges, particularly balancing need growth with preservation plateau's delicate ecosystem. In this study, we take into account intricate interplay between human activities, environmental conditions, strategies. By applying pressure-state-response (PSR) framework innovatively establishing comprehensive potential evaluation index, are able to quantify development deposits on QXP identify key factors influencing potential. results indicate varied landscape deposit across QXP. state layer PSR model represents most significant obstacle Certain areas, specifically central Xizang, eastern northwestern Yunnan, show high due favorable conditions policy environments, strong infrastructure.

The alpine steppe has an important place in ecosystems, and its distribution pattern is strongly influenced by climate change. In this study, we used “biomod2” “FragStats 4.2” to calculate the migration trends habitat fragmentation of three S. purpurea steppes on western Tibetan Plateau. results study show that Stipa purpurea-Ceratoides compacta steppe, purpurea-Carex moorcroftii montis-everestii are climate, while other variables have less impact. Their main influence factors annual precipitation (Bio12), warmest quarter (Bio18), coldest (Bio19), respectively. effects carbon emissions suitable habitats all significant future scenarios. Continued increases will lead a continuous reduction their areas. These communities bounded 33° N. South boundary, mountain ranges tendency migrate higher elevations southward direction. North northward Climate change reduces community aggregation, leading gradual fragmentation. findings provide scientific basis for conservation Plateau, thereby contributing improvement ecosystem stability species diversity.

Quantifying the spatiotemporal patterns of coordination between ecosystem service supply and demand is vital for regional sustainable development. To reveal dynamic pattern (ES) in Lhasa River Basin, we quantified following four ESs using InVEST model from 2000 to 2018: carbon sequestration (CS), water conservation (WC), habitat quality (HQ), soil (SC). Using socio-economic data, including land development degree, GDP, population density, ES was quantified. The supply–demand ratio (ESDR) coupling degree (CCD) were used evaluate relationship demand. spatial autocorrelation analysis determine correlation changes degree. results indicate that distribution ESDR exhibited significant heterogeneity. area with far greater than always upstream River, while Chengguan District exceeded supply. Grasslands forests main contributors ESDRs, providing positive ESDRs three services, SC, HQ, WC, a total proportion above 80%. From 2018, mismatch gradually spreading upstream, areas had relatively high CCD. correlations CCD basin all showed statistically differences (p < 0.01). high–high aggregation concentrated northeast basin, low–low centered around District. This study provides reference values optimizing use ecologically vulnerable goal

ABSTRACT Global warming is exhibiting a seasonal trend, while different seasons have variations. However, the impact of on plants remains unclear. This study employed Open Top Chambers (OTCs) to simulate future scenarios in alpine meadow. The examined plant community dynamics following long‐term warming. transcriptional and physiological responses two dominant species ( Kobresia pygmaea Stipa purpurea ) were examined. Results suggest that effects are correlated with both duration season which occurs. A long annual duration, especially growing warming, made confront various stresses. K. adopted stress‐avoidance strategy, showing negative response, leading population decline or disappearance. kind dieback had also been observed other Cyperaceae species. Meanwhile, due positive responses, S. stress‐tolerance strategy overcame partially gained dominance over Overall vegetation coverage diversity decreased years. These results reveal plants, explaining reasons for changes communities under providing new insights conservation
