Are bigger green spaces more diverse in terms of their natural and manmade elements? Does higher diversity mean they are more attractive to users and encourage more diversity of activities, and thereby provide a wider range of recreational ecosystem services? We assessed and classified the recreational services in green urban spaces in the city of Oslo, by combining multidimensional biophysical mapping based on the structural diversity index (SDI), with users’ importance scores as an approach to non-monetary valuation of urban parks. Our results reveal that size is a weak and non-linear determinant of structural diversity. On the other hand, stated preferences are correlated with structural elements. Urban green spaces classification could be improved by combining structural diversity indicators with structural preference studies. At the same time, our structural diversity measure did not cover the full range of recreational services across the spectrum of urban green spaces. We discuss potential extensions of the structural diversity index for urban green space in order to cover a wider range of green spaces – from cemetaries to peri-urban forest – and the recreational opportunities provided by them.

更大,更多样化,更好?绘制城市绿地中的结构多样性及其娱乐价值

更大的绿色空间在自然和人造元素方面是否更加多样化?更高的多样性是否意味着它们对用户更具吸引力并鼓励更多的活动多样性,从而提供了更多的休闲生态系统服务?我们通过结合基于结构多样性指数(SDI)的多维生物物理图谱和用户的重要性得分,对奥斯陆市绿色城市空间中的休闲服务进行了评估和分类,以此作为对城市公园进行非货币估值的一种方法。我们的结果表明,规模是结构多样性的弱且非线性的决定因素。另一方面,陈述的偏好与结构要素相关。通过将结构多样性指标与结构偏好研究相结合,可以改善城市绿地的分类。同时,我们的结构多样性指标并未涵盖整个城市绿色空间中的所有娱乐服务。我们讨论了城市绿地结构多样性指数的潜在扩展,以涵盖更广泛的绿地-从公墓到郊区森林-以及它们提供的休闲机会。
