抽象的。地球多样性的概念似乎是从围绕生物多样性的讨论中产生的，并且随着时间的推移不断发展成为一种工具和理论概念。本文概述了这一概念的演变，从而提出了这样的论点：地理多样性是一个比地质多样性更广泛的术语。因此，建议该概念应考虑到所有非生物要素、过程以及与自然系统和人类活动的关系。概述作为关注地质多样性构成要素的基础，这些构成要素导致生境、生态系统或景观的多样性丰富，并影响其在理论、教育和地理保护方面的使用。建议在非生物多样性的层次结构中包括四个层次（颗粒、元素、地点和景观）。讨论了测量和量化地球多样性的几种方法，指出需要一个地球多样性指数，将不同的物理要素与土壤、水文和地貌过程以及地形因素（方向、坡度和辐射）联系起来。
Abstract. The concept of geodiversity appears to have grown out of the discussions around biodiversity, and has evolved over time to become both a tool and a theoretical concept. The paper presents an overview of this conceptual evolution, leading to formulation of the argument that geodiversity is a broader term than geological diversity. Consequently, it is proposed that the concept should take into account all abiotic elements, processes and relations to the natural system and human activity The overview serves as a basis for focussing on the constituent elements of geodiversity that lead to the richness of variety in biotopes, ecosystems or landscapes and that infiuence its use in theoretical, educative and geoconservation terms. The suggestion is made to include four levels in a hierarchy of abiotic diversity (particles, elements, places and landscapes). several approaches to measuring and quantifying geodiversity are discussed, pointing to a need for a geodiversity index which links the different physical elements with processes in the soil, hydrology and geomorphology, as well as with topographical factors (orientation, slope and radiation).
