    Study on Water Environmental Characteristics Based on Comprehensive Pollution Assessment Method with Entropy Weight Optimization by HUANG Wen

    Published 2024-07-01
    “…At the same time, the comprehensive pollution assessment method, enhanced by entropy weight optimization, indicates that the water quality of Sand Lake in August is classified as category V, exceeding the standard, and the pollution level in summer and autumn in August is significantly higher than that in winter and spring, especially the monitoring point L05, indicating that the lake environment is significantly affected by wildlife such as birds and fish. Finally, the water environmental pollution index values of Sand Lake in 2020 are lower than those monitored in the same period of 2019, suggesting that the water quality of the lake shows an upward trend of change. …”
