Abstract Watershed ecosystems play a pivotal role in maintaining the global carbon cycle and reducing warming by serving as vital reservoirs for sustainable ecosystem management. In this study, we based on "quantity-mechanism-scenario" frameworks to evaluate stocks mid high latitudes alpine watersheds China explored mechanisms of climate change land use influence ability watershed store carbon. The results showed that stock increased about 15.9 Tg from 1980 2020. Vegetation, precipitation, land-use change, economic production have strongest explanatory power stocks. Under different scenarios, it was found SSP2-4.5 scenario had significant rise 2020 2050, roughly 24.1 Tg. This increase primarily observed southeastern region basin, with forest grassland effectively protected. Conversely, according SSP5-8.5 scenario, would decrease 50.53 expansion cultivated construction basin's southwest part. Therefore, given vulnerability mountain watersheds, trends continue pose greater threat sequestration watersheds. Our findings carry important implications tackling potential ecological threats Northern Hemisphere assisting policymakers creating plans, well change.

Accurately and timely quantifying the dynamics of urban sprawl is essential for improving land use efficiency planning. However, existing research mainly focused on a single city or agglomerations in China, while national scale studies used short-term remote sensing data to quantify sprawl. Therefore, we still lack long term most up-to-date understanding especially different regions, cities sizes. Here, quantified spatiotemporal using index (USI) based latest population census, analyzed its driving force China during 2000 ~ 2020 optimal parameters-based geographical detector. The results showed that past two decades, Chinese were experiencing sprawl, with an average USI 3.04, indicating annual growth rate lands was 3.04% higher than population. Overall, slowdown, dropping from 3.55 2010 2.53 2020. Among more severe western region, where 5.33 89.3% exceeded speed. Recently, transportation substantially increased. In future, Territorial Spatial Planning should pay attention confining excessive small- medium-sized region China.

Introduction Karst regions are integral to the global carbon cycle. However, land use changes of karst driven by urbanization and desertification contribute instability storage, leading uncertainties in future. Understanding these instabilities is crucial for formulating sequestration management strategies. Methods This study employed Patch-generating Land Use Simulation (PLUS) Integrated Valuation Ecosystem Services Trade-offs (InVEST) estimate introduced Coefficient Variation (CV) assess uncertainty. Multiscale Geographically Weighted Regression (MGWR) was applied explore mechanisms, while Polynomial (PR) identified stable intervals factors, informing land-use policies. Results Discussion (1) From 2000 2020, Guiyang’s storage rose from 136.62 Tg 142.13 Tg. By 2035, projections under natural development, urban expansion, ecological protection scenarios increases 147.50 Tg, 147.40 147.82 respectively.

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.

Karst topography comprises a fragile ecological environment with significant potential for carbon sequestration. It is characterized by severe rocky desertification, particularly in China’s karst fault basin. Therefore, there crucial need to scientifically evaluate the variations storage over time and space this area ensure effective land planning regional security, especially considering dual target. Using use data (1985–2020) from basin Southwest China, study employed InVEST model temporal spatial storage. A span of 35 years was examined, predictions regarding 2050 were formulated under three different conditions: natural evolution, protection, cultivated protection. These based on natural, social, economic driving factors. The results revealed fluctuating downward trend regards 1985 2020, total decrease 2.1 × 106 t. After 2000, has been improvement dynamic degree forest land, grassland, construction compared levels before 2000. Additionally, many types high density transitioned into those lower density. Spatially, higher north central southern basins. At county scale, except northern parts area, remaining counties. By 2050, protection scenario, projected increase approximately 6 t, whereas evolution scenarios, it expected 2 t 3 respectively. Specifically, only five counties will experience an storage, while other witness decrease. findings offer scientific basis enhancing ecosystem services through management practices control desertification They can inform decision-making processes sequestration, restoration, sustainable region.
