Bibliometric Analysis of Ancient Tree Protection Trends Based on Web of Science and China National Knowledge Infrastructure

In order to understand the current situation and development trend of ancient tree protection research, this study retrieved relevant research publications in the past 30 years from the Web of Science（ WoS）and China National Knowledge Infrastructure（ CNKI）database.“Bibliometrix” tool and VOSviewer software were employed to visualize relevant indicators.The findings indicate that ancient tree protection research has garnered significant global attention in recent years.The United States and China were the two countries with the largest number of publications in this field, and China has gradually become the backbone of research in this field.While extensive international collaboration exists, author collaboration remains limited; the journal with the most publications were “FOREST ECOLOGY AND MANAGEMENT” and “Land Greening”;research hotspots are shifting toward biodiversity, the health of large ancient trees, and beautiful rural landscapes.
