本文分析了非洲象分布区国家大象管理和象牙贸易政策的生态理念。围绕国际象牙贸易的讨论越来越多地集中在销售库存象牙和其他大象产品可能产生的潜在收入上。然而，象牙的国际贸易受《濒危野生动植物种国际贸易公约》（CITES）的监管，该公约承认“国际合作对于保护某些野生动植物物种免受国际贸易的过度开发至关重要”。因此，支持象牙贸易的论点必须涉及保护目标，而有关象牙贸易的争论已与有关大象种群管理的争论以及有关大象栖息地和稀树草原生态系统恢复力或其他方面的生态假设联系在一起。在本文中，我们研究了象牙合法化国际贸易的论点的生态方面，并讨论了生态理解的进步如何影响未来对这个有争议的问题的讨论。(C)2003 Elsevier Ltd.保留所有权利。
This paper provides an analysis of the ecological ideas which underpin policies of elephant management and ivory trading in African elephant range states. Increasingly, the discussion surrounding the international trade in ivory has focussed on potential revenue that could be generated from the sale of stock-piled ivory and other products derived from elephants. However, the international trade in ivory is regulated by Convention on International Trade in Endangered Species (CITES), which recognises that "international co-operation is essential for the protection of certain species of wild fauna and flora against over-exploitation through international trade". Thus, the arguments in favour of ivory trading must refer to conservation objectives, and controversies over the ivory trade have become linked to debates over the management of elephant populations, and ecological assumptions regarding elephant habitat and the resilience or otherwise of savanna ecosystems. In this paper, we examine the ecological aspects of the arguments for a legalised international trade in ivory, and discuss how advances in ecological understanding could influence future discussion of this controversial issue.
