城市中大量的绿色空间草坪意味着它们庇护了很高比例的野生城市物种，但景观和管理在这些空间中生物多样性水平上的作用却鲜为人知。我们在法国巴黎东南角的100块草坪上进行了植物区系调查，并将其植物区系多样性和组成与以下因素联系起来：（1）土地利用模式和与巴黎市中心的距离赋予的城市化特征，（2）当地因素，包括草坪的亮度和大小，（3）管理类型，包括杀虫剂和肥料的使用，动物和公共通道，和割草频率。共鉴定出79种，其中9%为归化种。物种的分布在很大程度上取决于适用于绿色空间的管理方法：特定的管理策略与特定的社区特征和组成。正如预期的那样，最高的物种丰富度和/或稀有度是在私人管理的草坪中发现的，杀虫剂的使用率低，公众进入有限。但令人惊讶的是，在小型公共草坪中有时也会发现高度的多样性。研究结果建立了人类活动与植物群落特征之间的关系。我们利用它们提出了几项建议，就如何最好地优化草坪管理，以保护城市生物多样性。(C)2011爱思唯尔有限公司版权所有。
The large number of green space lawns in cities means that they shelter a high proportion of wild urban species, but the roles of landscape and management on the level of biodiversity in these spaces are little understood. We performed floristic inventories in 100 lawns in the southeast corner of Paris, France and linked their floristic diversity and composition to: (1) the characteristics of urbanization given by the Land Use Pattern and the distance from the centre of Paris, (2) local factors including luminosity and size of the lawn and (3) the type of management, including pesticide and fertilizer use, animal and public access, and mowing frequency. A total of 79 species were identified, of which 9% were naturalized. Distribution of the species was largely conditioned by the management methods applied to the green spaces: specific management strategies were associated with specific community traits and composition. As expected, the highest species richness and/or rarity were found in lawns submitted to private management, low use of pesticides and limited public access. But surprisingly high diversity was also sometimes found in small public lawns. The results establish relationships between human practices and characteristics of plant communities. We use them to make several recommendations on how best to optimize management of lawns with a view to conserving urban biodiversity. (C) 2011 Elsevier B.V. All rights reserved.
