The Middle Route of the South-to-North Water Diversion Project is a critical infrastructure that ensures optimal water resource distribution across river basins and safeguards livelihood people in China. This study investigated its effects on land surface temperature (LST) fractional vegetation coverage (FVC) Danjiang River Basin. Moreover, it examined spatial temporal patterns this project, providing scientific basis for safe supply ecological preservation. We used improved interpolation mean anomaly (IMA) method based digital elevation model (DEM) to reconstruct LST while FVC was estimated using image element dichotomous model. Our findings indicated general increase average Basin post-project implementation. During both wet dry seasons, cooling effect primarily observed south-central region during daytime, with extreme values 6.1 °C 5.9 °C. Conversely, nighttime, more prevalent northern region, 3.0 2.3 In contrast, warming seasons predominantly located 5.3 5.5 At night, chiefly 5.8 displayed seasonal trend, higher season overall improvement over time. Statistical analysis revealed negative correlation between change daytime variations periods (r = −0.184, r −0.195). Furthermore, significant positive existed nighttime changes 0.315, 0.328). Overall, project contributed regulating LST, fostering development, enhancing stability

Net primary productivity (NPP) is a core ecological indicator within terrestrial ecosystems, representing the potential of vegetation growth to offset anthropogenic carbon emissions. Thus, assessing NPP in given region crucial for promoting regional restoration and sustainable development. This study utilized CASA model GEE calculate annual average Shandong Province (2001–2020). Through trend analysis, Moran’s Index, PLS−SEM, spatiotemporal evolution driving factors were explored. The results show that: (1) From 2001 2020, showed an overall increasing trend, rising from 254.96 322.49 g C·m⁻2/year. shift was accompanied by gradual eastward movement centroid, indicating significant spatial changes productivity. (2) Regionally, 47.9% experienced improvement, 27.6% saw slight 20.1% exhibited degradation, highlighting notable heterogeneity. (3) Driver analysis that climatic positively influenced across all four periods (2005, 2010, 2015, 2020), with strongest impact 2015 (coefficient = 0.643). Topographic such as elevation slope also had positive effects, peaking at 0.304 2015. In contrast, human activities, especially GDP nighttime light intensity, negatively impacted NPP, negative effect 2010 −0.567). These findings provide valuable scientific evidence ecosystem management offer key insights development strategies national level.

Abstract Assessing the effectiveness of vegetation restoration along Yangtze River shoreline and exploring its relationship with land use changes are imperative for providing recommendations sustainable management environmental protection. However, impact post-implementation Conservation Project remains uncertain. In this study, utilizing Sentinel-2 satellite imagery Dynamic World data from pre- (2016) post- (2022) periods, pixel-based binary models, transition matrices, geographically weighted regression models were employed to analyze status evolution coverage shoreline. The results indicated that there had been an increase in area covered by high high-medium levels. proportion cover shifting better was 4201.87 km 2 (35.68%). Hotspots improvement predominantly located River. Moreover, areas witnessing enhanced experienced notable changes, notably conversion water crops (126.93 , 22.79%), trees (59.93 10.76%), built 10.76%). Notably, between emerged as a significant factor influencing improvement, average coefficients 0.68 0.50, respectively. These outcomes underscore significance study guiding ecological protection

Grasslands are important terrestrial ecosystems and key sources of primary productivity for livestock on Earth. It is very to clarify the trend balance between grassland sustainable development. Focusing unique alpine ecosystem that widely distributed in Tibetan Plateau (TP), we assessed carrying capacity (GCC) overgrazing 2000, 2010 2020 considering productivity, forage utilization different types, loss from diseases pests actual grazing intensity. Structural equation modelling was used analyse multifactor interactive driving mechanism changes GCC overgrazing. The results showed 1) From 2000 2020, although total area decreased slightly, amounts edible forage, utilization, pests, increased by 21.29%, 21.08%, 22.25% 15.90%, respectively. 2) first intensified then alleviated TP, but there a serious grass-livestock imbalance (overgrazing ratio 119% 2020), with 80% its counties being overgrazed 2020. 3) climate change ecological protection created synergistic effects TP.

Nevertheless, cumulative and lagged effects WUE across different grassland types China remain unclear. This study investigates from 1982 to 2018. We employed Sen-MK trend test correlation analysis identify primary factors influencing temporal WUE. The results indicated that Chinese grasslands, various types, exhibited an upward over time, with most rapid increase observed meadow. Drought had both WUE, lasting average 5.2 months 6.1 months. Specifically, lasted 5.6 alpine subalpine meadow, slope, desert grassland, whereas 9 plain grassland. Furthermore, influence varied intensified increasing altitude. trends impacts aridity index (AI) zones were consistent those as a whole. Our findings underscore response their distinct primarily characterized by effects. research provides important reference value enhancing stability ecosystems.
