This work proposes a water quality model based on the pooled effects of nitrate, nitrite, ammonium, and orthophosphate concentration as the main causatives of environmental water quality changes. One of the main characteristics of the model is assigning an environmental weight for each variable (zeta(i)) according to threshold concentrations of nutrients capable of inducing water changes condition. The model validation demonstrated adequate sensitivity to different data arrangements; as observed in an arid climate bay, showing annual stratification resulting in a variable content in nitrogen-forms and phosphorous. The model can be continuously calibrated over time by adding more N and P data to specific nutrient functions, and tested on sites with high NO(3), NO(2) or NH(4) concentrations.
这项工作提出了一种水质模型，该模型基于硝酸盐、亚硝酸盐、铵和正磷酸盐浓度的综合影响，这些是环境水质变化的主要成因。该模型的一个主要特点是根据能够引发水质变化状况的营养物质阈值浓度，为每个变量（ζ(i)）赋予一个环境权重。模型验证表明，该模型对不同的数据排列具有足够的敏感性；如在一个干旱气候海湾中观察到的那样，显示出年度分层导致氮形态和磷含量的变化。通过向特定营养物质函数中添加更多的氮和磷数据，该模型可以随时间不断校准，并在硝酸盐、亚硝酸盐或铵浓度较高的地点进行测试。
