Prediction marine ecosystem health decision

项目摘要

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 willuse statistical techniques to avoid arbitrary construction of indices and produce a software system to select the relative importance of different indices in contributing to an overall indicator of ecosystem health. Working with Fisheries and Oceans Canada, Environment Canada, and several provincial agencies, we intend to deliver a decision support tool that will enable further capability to manage the coastal zone.

加拿大拥有广阔的沿海地带，从事各种用途，包括工业、渔业、水产养殖、旅游、住宅和农业。在许多情况下，进入沿海河口和海湾的物质在其他方面是有毒或有害的，例如刺激植物过度生长的营养物质。负面影响影响了这些地区的完整性，损害了所谓的生态系统健康。各个政府机构都有监督沿海地区和维持生态系统健康的任务。这种保护的一个方面包括提前预测负面影响，以便将鱼类植物排放等活动调节到不损害生态系统的水平。我们提出的研究目标是开发简单的工具，为管理者提供预测能力。在了解不同的过程如何引入和去除水中和底部沉积物中的各种物质的基础上，我们将推导出一系列生态系统健康指数。我们将使用统计技术来避免指数的任意构建，并开发一个软件系统来选择不同指数在生态系统健康总体指标中的相对重要性。我们打算与加拿大渔业和海洋部、加拿大环境部和几个省级机构合作，提供一种决策支持工具，使管理沿海地区的能力得到进一步提高。
