摘要: 城市扩展是导致生境破碎化和生物多样性下降的重要原因之一,强烈改变城市景观,也改变生态过程。土壤动物是城市生态系统的重要组成部分,可对快速城市化进程及其带来的影响做出相对灵敏的响应,具有典型的环境指示作用。城市生态系统的干扰因素较复杂,土地利用类型不能完全反映土壤动物局地生境差异,这使得城市景观格局对土壤动物多样性的影响问题长期以来缺乏系统研究。为了解决城市化导致的生境丧失与土壤动物多样性保护的矛盾,本文探讨了不同城市化梯度区景观格局对土壤动物多样性的影响研究进展,试图揭示景观尺度多种生境类型的土壤动物分布规律,为城市土壤动物多样性保护提供一种新的思路,丰富城市景观生态学的研究内容。

Abstract: Urbanization is one of the main reasons for biodiversity reduction and habitat fragmentation, which changes urban landscapes and ecological processes. Soil fauna is a significant component of urban ecosystems. It could make quick responses to rapid urbanization, being a typical environmental indicator. Due to the complicated disturbance factors of the urban ecosystem, the land use type could not fully reflect local habitat differences of soil fauna. It remains unclear about the influence of urban landscape pattern on soil fauna diversity. Aiming at solving the conflict between habitat loss and soil fauna diversity protection caused by urbanization, we summarized research progress on the impacts of urban landscape pattern on soil fauna biodiversity along urbanization gradient, to reveal the patterns of soil fauna distribution in different habitats in landscape scale. This review provides a new thought for the protection of urban soil fauna diversity and enriches the contents of landscape ecology.
