The mechanisms driving changes in the stability of phosphorus (P) sediments under lake ecosystem degradation remain poorly understood. This study investigated P-binding forms from three plateau lakes with different trophic states Yunnan Province, China, aiming to elucidate responses sediment P compositions human activities, status, and dissolved organic matter (DOM) characteristics. results showed that activity directly contributed retention. type exerted a discernible effect on mobility sediments, as eutrophic algae-type had higher content mobile-P. Moreover, DOM promoted adsorption BD-P NH4Cl-P. Generally, exogenous pollution caused by leads eutrophication decline stability. variation was largely influenced water depth. A decrease increased which increases risk endogenous pollution. plays an important role P. These insights offer novel perspective for understanding how characteristics are related loads lakes.

Promoting positive emotional experiences for tourists is crucial sustaining development in rural areas. However, existing research has limited focus on the built environment, particularly developing a framework to evaluate environmental sentiment small medium scale with detailed indicators. This study addresses this gap by examining impact of environment tourists' emotions. Natural Language Processing (NLP) technologies are employed analyze web text data and determine average index traditional villages Fuzhou, China. Additionally, were acquired through HRnet segmentation model Matlab. To assess association between indicators index, we used eXtreme Gradient Boosting (XGBoost), SHapley Additive exPlanation (SHAP) model, ArcMap software. The demonstrated that (1) spatial distribution was significant. Houfu Village (9.91), Qianhu (9.88), Ximen (9.75) had highest scores, while Doukui (−0.85), Jiji (0.2), Qiaodong (0.55) lowest.

Exploring the spatiotemporal impacts of climate change and human activities on freshwater resources through concepts blue green water can effectively improve sustainability basin resource management. However, previous relevant studies have not considered specific different models land use changes future simultaneously. To mitigate this issue, study proposes a hydrological modeling framework by integrating geographic detectors, Future Land Use Simulation (FLUS) models, Soil Water Assessment Tool (SWAT) model. This was capable identifying major driving factors changes, predicting patterns, assessing characteristics under scenarios distributions. Applying to Wei River Basin (WRB) in northwest China, it identified primary drivers WRB quantitatively analyzed four scenarios. The results show that: 1) FLUS model SWAT simulate runoff process with high simulation accuracy; 2) Precipitation, temperature GDP are main change; 3) amount middle lower reaches is significantly higher than that tributaries upper reaches. Blue flow more affected use, while storage sensitive change. provide effective information for planning rational allocation resources.

Under climate change and human activities, ecosystem service (ES) research lacks systematic approaches scientific depth. This study develops a comprehensive framework integrating advanced models to predict ESs, analyze interactions, identify key drivers, assess spatial effects on the Zoigê Plateau. The results indicate following: (1) From 2000 2020 across three 2040 scenarios, water conservation (WC) improves, while carbon storage (CS) habitat quality (HQ) decline, leading overall ES degradation. Core areas face rising degradation risks from 9% 29% under increasing environmental stress (SSP119 SSP585). (2) importance follows HQ > CS SC WC, with bivariate interactions outperforming single-factor effects. Future scenarios show weakened correlating higher ecological stress, indicating stability risks. (3) Land use (>40% explanatory power) is primary driver, urban expansion, slope, evapotranspiration, precipitation contribute (6–12%). (4) drivers showed weak patterns but became more stable future suggesting stronger control. provides methodological paradigm for analysis supports planning in alpine wetland–grassland regions.
