减轻全球生物多样性丧失的努力往往侧重于保护大型、完整的自然栖息地。然而，保护生物多样性也应该是城市环境的一个重要目标，特别是在自然栖息地所剩无几的高度城市化地区。在城市/县一级以及景观一级的研究越来越多地表明，城市地区可以拥有相对较高的生物多样性。在城市森林中发现了周围自然栖息地中发现的物种的重要百分比，包括濒危物种，这一贡献简要地突出了世界各地城市生物多样性研究的一些例子。在了解影响城市生物多样性的模式和过程，如城市-农村梯度和生物同质化的关键问题，得到解决。城市规划者和城市林业工作者需要认识到城市地区蕴藏着大量生物多样性的潜力，以便采取保护和促进这种多样性的管理做法。管理备选方案应侧重于增加城市森林各个方面的生物多样性，从行道树到城市公园和林地。(c)2006年Elsevier GmbH。All rights reserved.
Efforts at mitigating global biodiversity loss have often focused on preserving large, intact natural habitats. However, preserving biodiversity should also be an important goal in the urban environment, especially in highly urbanized areas where little natural habitat remains. Increasingly, research at the city/county scale as well as at the landscape scale reveals that urban areas can contain relatively high levels of biodiversity. Important percentages of species found in the surrounding natural habitat, including endangered species, have been found in the urban forest.This contribution concisely highlights some examples of urban biodiversity research from various areas of the world. Key issues involved in understanding the patterns and processes that affect urban biodiversity, such as the urban-rural gradient and biotic homogenization, are addressed. The potential for urban areas to harbor considerable amounts of biodiversity needs to be recognized by city planners and urban foresters so that management practices that preserve and promote that diversity can be pursued. Management options should focus on increasing biodiversity in all aspects of the urban forest, from street trees to urban parks and woodlots. (c) 2006 Elsevier GmbH. All rights reserved.
