城市小型水体，如池塘，是人类社会经济景观的基本要素。池塘还为那些在城市环境中无法生存的物种提供了重要的栖息地。了解城市池塘的生物多样性及其生态价值与城市化和社会经济地位相关因素之间的关系，对于决定在何处以及如何建立和管理城市池塘以实现最大的生物多样性效益至关重要。我们的研究调查了城市池塘生物多样性的模式是否与不同的社会经济因素有关，例如财富水平、教育程度或不同类型建筑的百分比。由于以往的研究缺乏对这一问题的研究，本研究具有探索性的特点，并使用了许多不同的变量。我们发现水生昆虫的生物多样性与城市化变量（如建筑物数量和居住在池塘周围的居民数量）呈显著负相关。这种关系并不因我们调查的空间尺度而有所不同。相比之下，我们没有发现与代表社会经济地位的变量，如教育水平和财富的人显着的关系。后一个结果表明，居民的社会经济地位不会导致任何特定的影响，在管理和池塘的功能，将影响生物多样性。然而，有必要对不同潜在机制进行更精细的调查，不同社会经济地位地区的居民可能会间接影响池塘。
Urban small water bodies, such as ponds, are essential elements of human socio-economic landscapes. Ponds also provide important habitats for species that would otherwise not survive in the urban environment. Knowledge on the biodiversity of urban ponds and the relationship between their ecological value and factors linked to urbanization and socio-economic status is crucial for decisions on where and how to establish and manage ponds in cities to deliver maximum biodiversity benefits. Our study investigates if the pattern of urban-pond biodiversity can be related to different socio-economic factors, such as level of wealth, education or percentage of buildings of different types. Because of lack of previous studies investigating that, our study is of exploratory character and many different variables are used. We found that the biodiversity of aquatic insects was significantly negatively associated with urbanisation variables such as amount of buildings and number of residents living around ponds. This relationship did not differ depending on the spatial scale of our investigation. In contrast, we did not find a significant relationship with variables representing socio-economic status, such as education level and wealth of people. This latter result suggests that the socio-economic status of residents does not lead to any particular effect in terms of the management and function of ponds that would affect biodiversity. However, there is a need for a finer-scale investigation of the different potential mechanism in which residents in areas with differing socio-economic status could indirectly influence ponds.
