摘要
Abstract
Based on the monitoring data from 2015 to 2023,the eutrophication status of three monitoring sections of Shifosi Reservoir in Shenyang City,Liaoning Province and its trend with time were evaluated by using the comprehensive nutritional status index method.After detailed analysis,the results show that during the observation period from 2015 to 2023,the nutritional status index of Shifosi Reservoir showed a relatively stable state,and did not show a significant trend.The comprehensive nutrition index changes in the range of 53.47～63.13,indicating that Shifosi Reservoir has reached a state of mild eutrophication to moderate eutrophication.Using a linear regression analysis method,the comprehensive nutritional status index values of each section within 5 years were scientifically predicted.After comparative analysis,the deviation between the prediction results and the actual monitoring data in 2023 is small,indicating that the prediction method has high reliability.On this basis,the cumulative probability density model was further used to predict the eutrophication risk of Shifosi Reservoir.The prediction results show that the probability of eutrophication risk in Shifosi Reservoir shows an increasing trend year by year.This trend should arouse our attention and take corresponding measures to deal with i.关键词
