Prediction of marine ecosystem health: a decision support tool for coastal management

加拿大有一个巨大的海岸带，正在进行各种用途，包括工业、渔业、水产养殖、旅游业、住宅和农业。在许多情况下，引入沿海河口和海湾的物质在其他方面是有毒的或有害的，例如刺激植物过度生长的营养物质。负面影响影响这些地区的完整性，损害所谓的生态系统健康。各个政府机构都有监督海岸带和维持生态系统健康的任务。这种保护的一个方面包括预先预测负面影响，以便可以将诸如鱼草排放等活动调节到不损害生态系统的水平。我们在拟议研究中的目标是开发简单的工具，为管理者提供预测能力。基于对不同过程如何引入和去除水和底层沉积物中各种物质的理解，我们将得出一系列生态系统健康指数。我们会

Canada has a huge coastal zone undergoing a variety of uses including industry, fisheries, aquaculture, tourism, residential, and agriculture. In many cases, substances introduced to coastal estuaries and bays are toxic or harmful in other ways, e.g. nutrients stimulating excess plant growth. Negative impacts affect the integrity of these areas, harming what is referred to as ecosystem health. Various government agencies have a mandate to oversee the coastal zone and maintain ecosystem health. One aspect of this protection involves prediction in advance of negative effects so that an activity such as fish plant discharge can be regulated to a level that does not harm the ecosystem. Our goal in the proposed research is to develop simple tools to provide managers with predictive capability. Based on an understanding of how different processes introduce and remove various materials in the water and bottom sediments, we will derive a series of indices of ecosystem health. We will
