abstract = "The ecological security of the water environment is a key element in evaluating the dynamic balance and ecological service functions in the construction of urban ecological civilizations. Through the regional study of water resources in Huizhou, we selected 24 indicators in five dimensions of the DPSIR theory, such as “driving force-pressure-state-impact-response”, and constructed an ecological evaluation index system of the water environment. Combined with the entropy weight TOPSIS model, the analysis was carried out for spatial differentiation features and spatio-temporal deduction features, and the results showed that the weight coefficients of the spatial differentiation features for the guideline layer exhibited significant stratification characteristics. The overall spatial and temporal interpretation characteristics of the water{\textquoteright}s environmental ecology in the Huizhou region from 2016 to 2021 showed a pull-up enhancement effect. The relative proximity value showed a 63.43% increase from 0.361 in 2016 to 0.590 in 2021 over the six-year period. The region is characterized by regional differences in the ecological carrying capacity of the water environment, which is high in the south-east and low in the north-west. The top three areas in the quantitative calculation of the ecological carrying capacity of the water environment are Shexian County, Jixi County, and Qimen County, in that order.",

N2 - The ecological security of the water environment is a key element in evaluating the dynamic balance and ecological service functions in the construction of urban ecological civilizations. Through the regional study of water resources in Huizhou, we selected 24 indicators in five dimensions of the DPSIR theory, such as “driving force-pressure-state-impact-response”, and constructed an ecological evaluation index system of the water environment. Combined with the entropy weight TOPSIS model, the analysis was carried out for spatial differentiation features and spatio-temporal deduction features, and the results showed that the weight coefficients of the spatial differentiation features for the guideline layer exhibited significant stratification characteristics.
