摘要: Abstract Current ecological risk assessment and controlling element identification methods of harmful algal blooms (HABs) are not connected. Here, we identified the elements by correlation principal component analyses, analytic hierarchy process. A compound eutrophication index ( CEI ) integrating with was constructed verified using data collected from Jiaozhou Bay, China. The results agreed chlorophyll-a concentration main results. HAB more efficient than that nutrient quality Assessment Estuarine Trophic Status. contribution ratio loads concentrations nutrients (nitrogen, phosphorus, chemical oxygen demand) to HABs in Bay 70%. In high-risk areas, 77%. Therefore, terrestrial inputs must be reduced prevent control north-eastern areas Bay.
