摘要：Recently, biodiversity and its conservation have gathered much attention. However, the concept of biodiversity is not sufficiently understood in general and conservation measures in urban areas, particularly highly developed urban areas, have not been adequately discussed. The present review begins with an introduction to the concept of biodiversity and some of the concrete threats to it. Next, the effects of the corridor, which has been often regarded as a promising measure for biodiversity conservation, are reviewed in terms of its positive and negative aspects. Finally, potential measures for biodiversity conservation in highly developed urban areas are proposed, such as amelioration of habitat quality in existing urban parks, improvement of the weeding procedure, and planning conservation procedures based on predictive models.
