Understanding and mitigating the effects of phosphorus (P) overenrichment of waters globally, including the evaluation of the global Sustainability Development Goals, requires the use of global models. Such models quantitatively link land use, global population growth and climate to aquatic nutrient loading and biogeochemical cycling. Here we describe, compare, and contrast the existing global models capable of predicting P transport by rivers at a global scale. We highlight important insights gained from the development and application of these models, and identify important near-term opportunities for model improvements as well as additional insight to be gained through new model analysis.

要了解和缓解全球水体中磷（P）过度富集的影响，包括对全球可持续发展目标的评估，就需要使用全球模型。这些模型将土地利用，全球人口增长和气候与水生养分含量和生物地球化学循环定量联系起来。在这里，我们描述，比较和对比了能够预测全球范围内河流中磷运移的现有全球模型。我们重点介绍了从这些模型的开发和应用中获得的重要见解，并确定了近期改进模型的重要机会，以及通过新模型分析将获得的其他见解。
