摘　　要：水分是植物材料不可分割的部分,与细胞壁材性紧密相关。研究水分与细胞壁之间的规律性,对细胞壁材料认知和高效利用意义重大。以竹材细胞壁水分为研究对象,综述了竹材纤维饱和点,不同尺度细胞壁水分特点、类型、作用机制,以及细胞壁水分的测试设备、测试方法等方面研究成果,分析了宏观尺度下吸湿解吸及滞后过程,阐明了竹材细胞壁水分变化特征,提出了竹材纤维饱和点研究的不统一性。针对竹材细胞壁水分分布、存在位置、变化规律以及与细胞壁的相互作用机制尚存在许多疑问,相关研究结论缺乏,期望加强基础研究,利用现有高新技术和先进研究方法,加大投入研究力量,为竹材细胞壁干缩湿胀、干燥基准、防霉防腐、耐久性等提供科学依据,推动竹材基础和应用研究的发展进程。Water content in biomass materials is closely related to the properties of cell wall materials,it is of great significance to study the regularity between them for the efficient use of cell wall materials.In this article,the research results on bamboo fiber saturation point,cell wall moisture type,and moisture related test equipment and methods were summarized.The non-uniformity of the bamboo fiber saturation point research was pointed out,the hygroscopic desorption and hysteresis processes were analyzed,and the characteristics of water change in the wood at the micro scale were summarized.There are still many questions to be answered about the distribution of water in the microscopic bamboo,its existence location,the changing rules and the interaction mechanism with the cell wall.It is necessary to promote the development of bamboo basic and applied research.
