Abstract

Urban areas have detrimental impacts on the ecosystems. Nevertheless, they still supply many ecosystem services (ES), such as Pollination, in different urban green spaces (UGS). Lawns are among the most degraded UGS due to very high human impact. Still, flowers such as Dandelions (Taraxacum officinalis) live in these spaces. These flowers are considered a suitable habitat for pollinators. In this work, we develop a methodology to map Pollination ES potential in urban lawns using an Unmanned Aerial Vehicle. A detailed protocol was developed using high-resolution images, consisting of orthomosaic creation, flower vectorisation, field validation, and finally, Pollination ES potential mapping using Kernel and Point Density. This method can be applied to urban lawns and grasslands in Spring and Summer.

•
A novel method was developed to map pollination potential in lawns.
•
Dandelions (Taraxacum officinale) were mapped using UAV high-resolution images.
•
The method is helpful to identify areas with pollination potential in urban lawns.

绘制城市草坪授粉生态系统服务潜力图的简单方法

城市地区对生态系统有不利影响。然而，在不同的城市绿地 (UGS) 中，它们仍然提供许多生态系统服务 (ES)，如授粉。由于人类的高度影响，草坪是退化最严重的 UGS 之一。尽管如此，蒲公英（Taraxacum officinalis）等花卉仍生活在这些空间中。这些花卉被认为是授粉者的理想栖息地。在这项工作中，我们开发了一种使用无人飞行器绘制城市草坪授粉 ES 潜力图的方法。我们利用高分辨率图像制定了详细的规程，包括创建正射影像图、花卉矢量化、实地验证，最后利用核密度和点密度绘制授粉ES潜力图。利用无人机高分辨率图像绘制了蒲公英（Taraxacum officinale）地图。
