关于保护高质量的荒野地区（即大而完整的景观）与保护具有高生物多样性价值的地区的相对重要性，有相当多的讨论。实现生物多样性保护的一个方面所需的地方不一定是另一个方面的最佳选择，这可能导致在分配保护优先事项时发生冲突。然而，两者对生物多样性保护都很重要，并具有社会，经济和生态价值。对（a）生物多样性要素（例如物种、生境）的代表性和（B）荒野保护的投资不仅是互补的，而且对生物多样性的长期持久性也很重要。我们开发了两种方法，以确定重要的野生质量和生物多样性代表性方面的生物多样性保护领域，澳大利亚作为一个案例研究。我们将完整区域定义为至少有70%或更多植被的子集水区，这些植被没有因土地清理而遭受广泛的栖息地丧失和破碎。第一种方法的目的是在原生植被完好的地区实现生物多样性的代表性目标。这种方法的结果将是极其昂贵的实施，因为他们需要很大一部分的土地。第二种方法旨在实现整个景观中任何地方的生物多样性代表性目标，同时强调确定空间紧凑的完整地区。这种方法的结果显示了保护的经济成本与包含完整原生植被的保护区大小之间的权衡。这份手稿提供了一个新的框架，确定具有成本效益的生物多样性保护的优先事项，包括荒野质量。(C)2009爱思唯尔有限公司保留所有权利。
There is considerable discussion about the relative importance of conserving high quality wilderness areas (i.e. large and intact landscapes) versus conserving areas with high biodiversity values. Places that are needed to achieve one aspect of biodiversity conservation are not necessarily optimal for another which can lead to conflict in assigning conservation priorities. However, both are important for biodiversity conservation, and carry social, economic, and ecological values. Investment in both (a) representation of elements of biodiversity (e.g. species, habitats) and (b) wilderness conservation is not only complementary but important for the long-term persistence of biodiversity. We develop two approaches to identify areas important for the conservation of biodiversity in terms of both wilderness quality and biodiversity representation, using Australia as a case study. We defined intact areas as sub-catchments with at least 70% or more vegetation that has not been subjected to extensive habitat loss and fragmentation as the result of land clearing. The first approach aims to achieve biodiversity representation goals in areas with intact native vegetation. The results of this approach would be extremely expensive to implement as they require a large portion of land. The second approach aims to achieve biodiversity representation goals anywhere across the landscape while placing a strong emphasis on identifying spatially compact intact areas. The results of this approach show the trade-offs between the economic costs of conservation and the size of conservation areas containing intact native vegetation. This manuscript provides a novel framework for identifying cost-effective biodiversity conservation priorities inclusive of wilderness quality. (C) 2009 Elsevier Ltd. All rights reserved.
