Abstract: Geological diversity, which includes the material composition and morphological characteristics of geological, hydrological, geomorphological and soil features as well as the diversity of processes among them, is an important component of natural diversity. How to effectively measure the distribution characteristics, interrelationships and the system composed of various elements of geodiversity, and then explore the origins of each element and its contribution to the ecosystem, is of great value to promote the protection of the community of life in the nature reserve. In this paper, a quantitative analysis of geodiversity in the Baishanzu National Park area has been carried out by using the modified Shannon entropy equation. It is concluded that the modified Shannon entropy equation could quantitatively analyze the spatial distribution characteristics of various natural factors, and most importantly, it could quantitatively express the degree of correlation between the spatial distributions of various natural elements, which is an important way to explore the intricate and complex relationship between them, and could help to achieve the objective of the conservation of the mountains, water, forests fields, lakes and grasses. It provides a new way of thinking for the quantitative study of the relationship between the life community from a single element to multiple elements.
