Spatial and quantitative assessments of water yield services in watershed ecosystems are necessary for resource management improved ecological protection. In this study, we used the InVEST model to estimate regional Dongjiang Lake Basin China. Moreover, designed six scenarios explore impacts climate land use/land cover (LULC) changes on quantitatively determined dominant mechanisms services. The results expected provide an important theoretical reference future spatial planning improvements service functions at source site. We found that (1) under time series analysis, showed initial decrease followed by increase. Spatially, also decreased from lake area surrounding region. (2) Climate change exerted a more significant impact changes, contributing than 98.26% variability basin. contrast, LULC had much smaller influence, only 1.74 %. (3) distribution pattern was vulnerable changes. particular, expansion built-up is increase depth alter its distribution, but it increases risk waterlogging. Therefore, development basin must consider protection spaces maintain stability function.

The biophysical modeling of water ecosystem services is crucial to understanding their availability, vulnerabilities, and fluxes. Among the most popular models, Integrated Valuation Ecosystem Services Trade-offs (InVEST) models stand out. While many studies have used them, few assessed performance. This study evaluates performance InVEST’s Seasonal Water Yield, Nutrient Delivery Ratio, Sediment Ratio in a subtropical basin southeastern Brazil on temporal spatial scales, using 39 years streamflow data, 29 for total phosphorus nitrogen, 19 suspended solids. Statistical indicators R2, PBIAS, NSE, were also calculated. varied according type simulated WES analysis scales used, with Yield model demonstrating best effectively representing variability average annual streamflow. All performed well simulating long-term mean values when compared observed data. one should bear mind study’s limitations, results indicate that perform terms relative magnitude, although application involving water-resource management decision making limited.

Understanding the relationship between water conservation service (WCS) and landscape patterns is important for ecosystem management resources regulation. However, existing studies on services pattern mainly focus impact of composition WCS, but ignore spatial effects configuration. Taking Erhai Lake Basin as an example, this study quantified temporal distribution WCS analyzed changes in configuration from 1990 to 2020. Subsequently, non-stationarity was discussed by using a geographically weighted regression model. The results showed that urban forest landscapes increased 3189.96% 18.34%, while grassland, shrub, cropland decreased 21.30%, 20.65%, 16.23%, respectively, fragmentation degree increased, other decreased. heterogeneity overall decreased, aggregation increased. 15.82% 2020, it derived landscape, which contributes more than 91% WCS. were spatially heterogeneous. mean patch density largest index positively affected 66.80%–82.88% 64.35%–72.42% regions, whereas area negatively impacted 66.64%–82.41% regions.

ABSTRACT Understanding the link between landscape pattern and water conservation service (WCS) is crucial for effective resource planning. However, impact of configuration on WCS remains unclear. This study explored spatiotemporal relationships in Zoige Plateau (ZP), a vital waterhead yellow river, from 1990 to 2020. The results showed that woodland high‐coverage grassland exhibited highest capacity contributed greatest total WCS, suggesting importance protecting coverage area grassland. From 2020, areas high‐ medium‐coverage grasslands significantly decreased, implying adverse effects composition changes ZP's during past few decades. metrics significant variability across years, climate scenarios regions, highlighting role climatic underlying surface. Under realistic scenarios, greater most parts western northern ZP, which negatively correlated with aggregation index, patch density, mean fractal dimension index but positively shannon's diversity it better increase proportion large patches, reduce fragmentation, maintain diverse types. Conversely, southeastern part central where an opposite correlation aforementioned metrics, maintaining simpler type higher connectivity may be useful. These findings provided important insights identifying sensitive affect optimizing landscapes sustain WCS.
