主 题：water quality criteria nutrient Yellow River Estuary frequency distribution classification and regression tree eutro-phication
摘 要：Ecological protection and high-quality development of the Yellow River basin are becoming part of the national strategy in recent *** Yellow River Estuary has been seriously affected by human ***,it has been severely polluted by the nitrogen and phosphorus from land sources,which have caused serious eutrophication and harmful algal *** criteria,however,was not developed for the Yellow River Estuary,which hindered nutrient management measures and eutrophication risk assessment in this key ecological function zone of *** on field data during 2004-2019,we adopted the frequency distribution method,correlation analysis,Linear Regression Model(LRM),Classification and Regression Tree(CART)and Nonparametric Changepoint Analysis(nCPA)methods to establish the nutrient criteria for the adjacent waters of Yellow River *** water quality criteria of dissolved inorganic nitrogen(DIN)and soluble reactive phosphorus(SRP)are recommended as 244.0μg L^(−1) and 22.4μg L^(−1),*** is hoped that the results will provide scientific basis for the formulation of nutrient standards in this important estuary of China.
