Cell wall water is a key factor affecting wood properties,and its state and characteristics have long been a research hotspot in wood science.The occurrence state and distribution pattern of moisture in cell wall and its interaction mechanism with wood mechanical properties offer fundamental guidance for optimizing wood processing and enhancing utilization efficiency.This review summarizes the recent research progress on the water state in wood cell wall and briefly introduces the basic concepts of classical models of wood moisture sorption theory.With the continuous advancement of technology,various new characterization techniques have been applied in the field of wood science,leading to the emergence of new ways to classify and name cell wall water.Although these different classification methods reveal the characteristics of water in wood cell wall from multiple dimensions,they also bring certain cognitive confusion to researchers in related fields.In order to form a unified naming norm,this paper reviews various classification methods of wood cell wall water and summarizes their research methods as well as their advantages and disadvantages,aiming to provide a perspective of cell wall water for the basic wood science study and promote the further development of the field.
