Abstract: Phyllostachys edulis is one of the most important economic forest resources in southern China. However,a large proportion of Phyllostachys edulis stands are characterized by low quality and low productivity,making their improvement and restoration a crucial research focus. At present,research on restoration models for such degraded stands lacks systematic synthesis and comprehensive review. In this study,bibliometric methods were applied using CiteSpace 6. 3. R1 to analyze relevant literature from the CNKI and Web of Science(WOS)Core Collection databases published between 1960 and 2024,with the aim of examining the research status and development trends in restoration models for low-quality and low-efficiency Phyllostachys edulis stands. The results indicate that the number of publications in this field has shown a steadily increasing trend. Chinese-language publications account for 93. 9% of the total,and research prior to 2015 was predominantly published in Chinese. English-language studies emerged later and remain relatively limited in number;however,they were mainly published in high-impact international journals. Research collaborations were primarily concentrated among core groups at the International Center for Bamboo and Rattan,Zhejiang A&F University and Fujian A&F University. Early studies mainly focused on improving yield and economic returns,whereas recent research had increasingly emphasized the effects of restoration models on productivity and ecosystem service functions. Furthermore,this study identifies six major types of low-quality and low-efficiency Phyllostachys edulis stands,summarizes their stand characteristics and underlying formation causes,and outlines the associated technical system for restoration models. Based on these findings,current research gaps and future research directions were proposed,providing a systematic reference for advancing research and guiding the practical improvement of degraded Phyllostachys edulis stands.
