Workshop on "Terrestrial and Aquatic Phosphorus Cycles in the Amazon Basin;" Caracas, Venezuela; December 1989

该项目将支持美国科学家参加由SCOPE赞助的研讨会，该研讨会将讨论南美洲亚马逊盆地陆地和水生磷循环的整合问题。讲习班的目标是收集和整合关于亚马逊流域磷循环的数据。讲习班将讨论磷的来源、汇和通量、生物活性磷的供应机制，并就碳、氮和硫的生物地球化学循环评价目前和预计的磷使用对环境的影响。这些资料将纳入一项区域分析。讲习班将汇集来自几个学科的公认专家，以评估目前对亚马逊流域磷循环的了解。讲习班的成果将是：1)发表所提出的立场和数据文件；2)确定需要仔细管理磷资源的领域，以优化粮食和纤维生产并尽量减少各种环境中的危害；3)开发概念模型和扩展模拟模型，以整合现有知识，更好地了解亚马逊流域碳、氮和硫的P循环。

This project will support U.S. scientists to participate in a SCOPE sponsored workshop that will address integration of terrestrial and aquatic phosphorus cycles in the Amazon Basin of South America. The goal of the workshop is to assemble and integrate data on the phosphorus cycle for the Amazon Basin. The workshop will address sources, sinks and fluxes of P, mechanisms of supply of biologically active P, and evaluate the environmental effects of current and projected use of phosphorus in relation to biogeochemical cycles of carbon, nitrogen, and sulphur. This information will be integrated in a regional analysis. The workshop will bring together recognized experts from several disciplines to evaluate current understanding of phosphorus cycling in the Amazon Basin. The products of the workshop will be 1) a publication of the position and data papers presented, 2) identification of areas where careful management of phosphorus resources will be required to optimize food and fiber production and minimize hazard in various environments, and 3) development of a conceptual model and extension of a simulation model to integrate existing knowledge and develop a better understanding of P cycling in relation to carbon, nitrogen and sulphur in the Amazon Basin.
