Unraveling the impacts of multiscale landscape patterns and socioeconomic development on water quality: A case study of the National Sustainable Development Agenda Innovation Demonstration Zone in Lincang City, Southwest China

Journal of Hydrology Regional Studies, Journal Year: 2024, Volume and Issue: 51, P. 101660 - 101660

Published: Jan. 19, 2024

National Sustainable Development Agenda Innovation Demonstration Zone in Lincang City, Southwest China Revealing the current water quality status rivers and reservoirs its drivers is crucial to achieving United Nations Goal 6 (SDG 6). We assessed spatial-temporal dynamics influence of natural socioeconomic factors on index (WQI) parameters using redundancy analysis (RDA) partial least squares path model (PLSPM). The results indicate following. (1) annual average values WQI City from 2018 2020 were 92.26, 92.06, 92.45, respectively. spring, summer, autumn, winter 92.48, 90.38, 92.68, 93.49, seasonal levels good or higher. However, spatial heterogeneity exists for some City. (2) highly complex. landscape composition, configuration, pollutant discharges are key affecting annually seasonally, a scale dependence observed. (3) Chemical physical directly affect WQI, particularly at small scales (100 m 500 buffer zones). have strong inhibitory effect (−0.79, −0.78) (−0.56, −0.72), whereas weak promoting (0.05–0.13). Landscape composition configuration indirectly WQI. In contrast, pollution discharge impact through their chemical factors. These findings demonstrate that social interact multiple ways, impacting reservoirs. This interaction depends scale. Therefore, it consider appropriate distance future land use planning, design planning Moreover, controlling wastewater industrial agricultural activities domestic usage vital ensuring high quality.

Estimating the water quality index based on interpretable machine learning models

Water Science & Technology, Journal Year: 2024, Volume and Issue: 89(5), P. 1340 - 1356

Published: March 1, 2024

Abstract The water quality index (WQI) is an important tool for evaluating the status of lakes. In this study, we used WQI to evaluate spatial characteristics Dianchi Lake. However, calculation time-consuming, and machine learning models exhibit significant advantages in terms timeliness nonlinear data fitting. We a model with optimized parameters predict WQI, light gradient boosting achieved good predictive performance. trained based on entire Lake coefficient determination (R2), mean square error, absolute error values 0.989, 0.228, 0.298, respectively. addition, Shapley additive explanations (SHAP) method interpret analyse identified main parameter that affects as NH4+-N. Within range Lake, SHAP NH4+-N varied from −9 3. Thus, future environmental governance, it necessary focus changes. These results can provide reference treatment lake environments.

Driving Factors and Variability of Cyanobacterial Blooms in Qionghai Lake, Yunnan–Guizhou Plateau, China

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 169 - 169

Published: Jan. 10, 2025

Qionghai Lake is an important freshwater source in the Yunnan–Guizhou Plateau. However, cyanobacterial blooms have been observed recently Lake, but their formation mechanism and control management are not well understood. Herein, phytoplankton, zooplankton, eutrophication, nutrients, biochemical indices were measured from May 2022 to April 2023. The results showed that predominated Anabaena sp. with a density of 1.11 × 107–18.87 107 cells/L. started northwestern area November then expanded entire lake until it peaked subsided February Protozoa dominated zooplankton while having no significant relationship Lake. trophic level index chlorophyll similar spatiotemporal trends density, water quality northwest was worse than other parts. Total nitrogen (TN) total phosphorus (TP) 0.41–0.54 0.021–0.045 mg/L TN TP positively correlated most environmental factor affecting bloom These findings might provide essential information for improving remediation
