Water Quality Evaluation and Prediction Analysis of Shiyang River Basin Based on Secondary Game Cloud Model
摘要
Abstract
[Objective]To verify the applicability of the secondary game cloud model method in Shiyang River Basin,based on in-depth analysis of water quality changes in Shiyang River Basin from 2018 to 2022,the main pollution factors of 8 monitoring sections are identified,and the main water quality indices of severely polluted sections are predicted in short term in order to provide decision basis for subsequent water quality research and water environment management in Shiyang River Basin.[Methods]Secondary game cloud model and single factor evaluation method were combined to analyze 8 main indices of W1~W8 water quality detection section in Shiyang River Basin,and the grey GM(1,1)prediction model was used to predict the main pollutant indices of heavily polluted section Result Resluts could be concluded as follows:(1)The upstream water quality of Shiyang River Basin remained good from 2018 to 2022,and the pollution was mainly concentrated in the middle and lower reaches near Wuwei City.Among the 8 selected sections,the W4 and W5 monitoring sections had more serious water pollution.The main pollutant indices were ammonia nitrogen,TP,COD and BOD5;(2)Through the grey GM(1,1)model prediction,ammonia nitrogen,COD and BOD5 concentrations of the W5 monitoring section in 2027 could meet the water quality requirements of class Ⅲ,class Ⅳ and class Ⅰ,respectively.The concentrations of ammonia nitrogen,COD and TP of W4 monitoring section could meet the water quality requirements of class Ⅳ,class Ⅳ and class Ⅱ,respectively.[Conclusion]From 2018 to 2022,the water quality of Shiyang River Basin improves year by year,and the pollution is mainly agricultural pollution.TP,dissolved oxygen,ammonia nitrogen,and sulfide are dominated in water quality evaluation of study area.The improved secondary game cloud model and grey GM(1,1)prediction model have good feasibility and applicability in Shiyang River Basin,and the evaluation result are in line with the reality.关键词
