Geoconservation and related quantitative and qualitative geodiversity assessments are gaining increasing attention. However, methodologies for measuring geodiversity at local scale are currently rare. Here, we present a framework for assessing local-scale geodiversity of different landforms using field-based and digital elevation model (DEM-) derived data from the Rokua UNESCO Global Geopark in Finland. We observed the presence or absence of various geodiversity elements, such as geological or topographical elements in our study sites, and used these data to quantify alpha (α), gamma (γ) and beta (β) geodiversity of various landforms. In addition, we measured topographical heterogeneity in the field and from DEMs. The results showed distinct patterns in the geodiversity and topographical variation of the landforms. The differences between α, γ and β geodiversity of different landforms were particularly clear. According to the results, measures of topographical variability can be used to some extent as surrogates for geodiversity, but the choice of optimal variables is context and scale dependent. These results provide perspectives for further local-scale geodiversity assessments in different study areas and are applicable for a range of purposes, from scientific research to practical management and geoconservation. This article is part of the Theo Murphy meeting issue ‘Geodiversity for science and society’.

当地规模的地质多样性量化框架：Rokua 联合国教科文组织世界地质公园的案例研究

地质保护以及相关的定量和定性地质多样性评估正受到越来越多的关注。然而，目前在局部范围内测量地球多样性的方法还很少。在这里，我们提出了一个框架，用于使用来自芬兰 Rokua 联合国教科文组织世界地质公园的基于现场和数字高程模型 (DEM-) 的数据来评估不同地貌的局部规模地理多样性。我们观察了研究地点是否存在各种地质多样性要素，例如地质或地形要素，并使用这些数据来量化各种地貌的α（α）、γ（γ）和β（β）地质多样性。此外，我们还通过 DEM 测量了现场的地形异质性。结果显示了地貌的地理多样性和地形变化的不同模式。不同地貌的α、γ、β地质多样性差异尤为明显。根据结果​​，地形变异性的测量在某种程度上可以用作地理多样性的替代，但最佳变量的选择取决于环境和尺度。这些结果为不同研究区域进一步进行当地规模的地球多样性评估提供了视角，并适用于从科学研究到实际管理和地质保护的一系列目的。本文是西奥·墨菲会议问题“科学与社会的地理多样性”的一部分。
