Shandong Province in China is rich in paleontological fossils and has a long history of fossil research. However, research on the distribution characteristics and potential factors of discovered fossil sites in Shandong Province is limited and insufficient, making it difficult to comprehensively plan for the protection and utilization of fossil sites in Shandong Province. The study constructs a basic geographical information system (GIS) database with 133 discovered fossil sites and geological and socio-economic data of Shandong Province and studies fossil sites’ spatial distribution characteristics and the spatial relationship with potential factors at a regional scale. The results are as follows: (1) The fossil sites in Shandong Province are concentrated in the mountainous area of central Shandong and the hilly area of the Shandong Peninsula, with significant uneven distribution characteristics, including two agglomeration areas and seven sub-agglomeration areas. (2) Natural geographical conditions, such as topography, paleogeography, and stratigraphy, play a positive role in the distribution of fossil sites, and there are apparent concentrations in the following areas: at an altitude greater than 100 m; the Lower Paleozoic and Cretaceous sedimentary rocks; and the active areas of paleo-tectonics. (3) A certain degree of negative correlation exists between socio-economic conditions, such as roads and population density, and the number of fossil sites, and a positive correlation exists between disposable personal income and those fossil sites. The operational procedure presented here is a simple, objective, applicable method that can enhance our understanding of the spatial distribution patterns and influencing factors of the discovered fossil sites of Shandong Province and support more effective and appropriate planning for paleontological heritage conservation.

China boasts abundant geoheritage, including numerous paleontological geosites; however, many of these geosites are currently at high risk of degradation and face considerable challenges in protection and management. Using Liaoning Province as a case study, this study employs Geographic Information Systems (GIS) and spatial analysis to conduct the systematic data mining of provincial paleontological geosites. We quantitatively examine their spatiotemporal distribution patterns, identify key natural and socio-economic factors influencing their spatial occurrence, and pinpoint areas at high risk of degradation. Results reveal that the distribution of paleontological geosites across prefectural-city, regional, and geological time scales is highly uneven, leading to significant disparities in scientific research, resource allocation, and geotourism development. Significant spatial correlations are observed between the locations of these geosites and natural parameters as well as socio-economic indicators, providing a theoretical foundation for designing targeted conservation measures and precise management strategies. Based on these findings, the study proposes a multi-scale geoheritage conservation framework for Liaoning, which systematically addresses protection strategies across three distinct dimensions: at the prefectural-level city scale, through precise basic management, systematic investigation, and differentiated protection measures; at the regional scale, by enhancing collaborative mechanisms and establishing an integrated conservation network; and at the geological time scale, by deepening value recognition and promoting forward-looking conservation initiatives. This study not only offers tailored recommendations for conserving paleontological heritage in Liaoning, but also presents a transferable research model for other regions rich in paleontological resources worldwide, thereby bridging the gap between geoheritage conservation needs and practical solutions.

China has made significant progress in paleontological heritage conservation. However, research and conservation efforts have predominantly focused on exquisitely preserved, movable specimens of high scientific value, leading to the relative neglect of in situ paleontological geosites which are critical for understanding fossil distribution patterns. To address this gap, this study employs a GIS approach to conduct a multifaceted spatial analysis of paleontological geosites in the BTH region as a representative case study. Our results reveal a pronounced spatiotemporal imbalance in the distribution of these geosites. Furthermore, their spatial configuration exhibits significant correlations with key physiographic factors—including elevation, stratigraphic distribution, and slope—as well as socioeconomic indicators such as population density, GDP density, and fiscal self-reliance ratio. This uneven distribution creates substantial conservation challenges, resulting in fragmented governance, a mismatch between local conservation capacities and needs, and potential biases in protection priorities toward specific regions or geological periods. In the BTH region, the distribution patterns of paleontological geosites are jointly shaped by physiographic, socioeconomic, and anthropogenic process factors. Elucidating the relationships between these drivers and the spatial distribution of geosites constitutes a critical foundation for advancing their scientific conservation and sustainable management. Drawing on broader interdisciplinary insights, currently peripheral paleontological heritage can be further transformed into strategic and sustainable resources.
