To scientifically evaluate the eutrophication degree of water bodies, based on the comparison and analysis of various eutrophication evaluation methods, convolutional neural network (CNN) was introduced to establish the convolutional-eutrophication (CNN-E) model. Based on the monthly-scale water quality and algae monitoring data of Honghu Lake from 2014 to 2019, the comprehensive nutrient index method, BP neural network method and CNN-E model were used to evaluate its eutrophication degree. The mean absolute error, root mean square error, coefficient of determination and Nash-Sutcliffe efficiency coefficient were used to evaluate the performance of the neural network model. The results show that Hong Lake was in a mild eutrophic state for a long time, and the eutrophication level was increasing. In terms of model performance, the four evaluation indexes of CNN-E model are better than BP neural network 0.166, 0.098, 0.078 and 0.087, respectively. The CNN-E model can provide technical support for the prevention and comprehensive management of eutrophication in lake water bodies.

为科学评价水体富营养化程度,在对比分析各种富营养化评价方法基础上,引入卷积神经网络(CNN),建立卷积-富营养化(CNN-E)模型。根据洪湖2014~2019年月尺度水质及藻类监测数据,采用综合营养指数法、BP神经网络法与CNN-E模型评价其富营养化程度,并采用平均绝对误差、均方根误差、决定系数和纳什效率系数评价神经网络模型性能。结果表明,洪湖长期处于轻度富营养状态,富营养化程度不断加重。模型性能方面,CNN-E模型四种评价指标分别优于BP神经网络0.166、0.098、0.078与0.087。CNN-E模型可为湖泊水体富营养化预防及综合治理提供技术支持。

为科学评价水体富营养化程度,在对比分析各种富营养化评价方法基础上,引入卷积神经网络(CNN),建立卷积-富营养化(CNN-E)模型。根据洪湖2014~2019年月尺度水质及藻类监测数据,采用综合营养指数法、BP神经网络法与CNN-E模型评价其富营养化程度,并采用平均绝对误差、均方根误差、决定系数和纳什效率系数评价神经网络模型性能。结果表明,洪湖长期处于轻度富营养状态,富营养化程度不断加重。模型性能方面,CNN-E模型四种评价指标分别优于BP神经网络0.166、0.098、0.078与0.087。CNN-E模型可为湖泊水体富营养化预防及综合治理提供技术支持。

To scientifically evaluate the eutrophication degree of water bodies, based on the comparison and analysis of various eutrophication evaluation methods, convolutional neural network (CNN) was introduced to establish the convolutional-eutrophication (CNN-E) model. Based on the monthly-scale water quality and algae monitoring data of Honghu Lake from 2014 to 2019, the comprehensive nutrient index method, BP neural network method and CNN-E model were used to evaluate its eutrophication degree. The mean absolute error, root mean square error, coefficient of determination and Nash-Sutcliffe efficiency coefficient were used to evaluate the performance of the neural network model. The results show that Hong Lake was in a mild eutrophic state for a long time, and the eutrophication level was increasing. In terms of model performance, the four evaluation indexes of CNN-E model are better than BP neural network 0.166, 0.098, 0.078 and 0.087, respectively. The CNN-E model can provide technical support for the prevention and comprehensive management of eutrophication in lake water bodies.
