耦合物理-生物模型能够将环境因素和物理流体动力学之间复杂的相互作用联系起来，模拟感染性病原体和有害藻华的生长、毒性和运输。这种模拟可用于评估和预测病原体和有害藻华对人类健康的影响。鉴于沿海社区在饮用水、海产品和娱乐方面对水生系统的广泛依赖和日益依赖，这种预测对于做出明智的资源管理决策至关重要。在这里，我们确定了在病原体/有害藻华与人类健康之间建立这种联系的三个挑战：预测浓度和毒性；确定人口与生态系统相互作用的时空尺度；并将对病原体/有害藻华种群动态的理解应用于管理策略。我们详细说明了满足这些挑战的需要，描述了如何使用建模方法，并讨论了在解决这些挑战方面向前推进的策略。
Coupled physical-biological models are capable of linking the complex interactions between environmental factors and physical hydrodynamics to simulate the growth, toxicity and transport of infectious pathogens and harmful algal blooms (HABs). Such simulations can be used to assess and predict the impact of pathogens and HABs on human health. Given the widespread and increasing reliance of coastal communities on aquatic systems for drinking water, seafood and recreation, such predictions are critical for making informed resource management decisions. Here we identify three challenges to making this connection between pathogens/HABs and human health: predicting concentrations and toxicity; identifying the spatial and temporal scales of population and ecosystem interactions; and applying the understanding of population dynamics of pathogens/HABs to management strategies. We elaborate on the need to meet each of these challenges, describe how modeling approaches can be used and discuss strategies for moving forward in addressing these challenges.
