Bamboo resources in China are rich, whether the bamboo seeds, areas and the accumulated amount are the top of the world or the annual output is the top, the bamboo grows fast, can be continuously utilized in one-time afforestation, has high strength and good toughness, and can be widely applied to the fields of buildings, furniture and the like instead of wood. However, the bamboo wood is not scientifically classified, so that the processing yield is low, the product performance is unstable, the overall strength is reduced, and the problems of product cracking, short service life and the like occur in the use process. However, the bamboo is a natural biomass material, and factors such as the type, age, growth characteristics, external environment and the like of the bamboo have certain influence on the appearance, size, performance and the like of the bamboo, so that the bamboo has great variability among the bamboo individuals. The mao bamboo material is formed by compounding two components of fiber and a matrix, the component content of the mao bamboo material has great variability in the wall thickness direction and the culm height direction, and the component properties are different, for example, the tensile elastic modulus and the tensile strength of the fiber are respectively 21.54 GPa and 473.08MPa higher than those of the matrix substance, the internode length of the mao bamboo is firstly increased and then reduced along the bamboo height direction, the surrounding diameter and the wall thickness are both reduced along the bamboo height direction, the basic density of the mao bamboo material is increased along with the increase of the bamboo height, and the influence of the height is obvious. The longitudinal variation of the tensile elastic modulus and the strength of the moso bamboo has variability in the axial direction and the radial direction, the radial variation is remarkable, the ratio of the tensile elastic modulus and the strength of the outermost layer to the innermost layer of the moso bamboo is 3-4 and 2-3 respectively, the bamboo age and the mechanical property of the moso bamboo have certain correlation, the mechanical property changes in a parabolic manner along with the increase of the bamboo age, wherein the state of the 4-year moso bamboo is optimal, the physical and mechanical properties such as density, shrinkage rate and strength of the bamboo are found to be influenced by comparing the four kinds of bamboo, and the main properties such as pressure resistance and bending resistance of the moso bamboo along the grain are remarkably influenced by the altitude and the slope direction.

Therefore, the bamboo wood is greatly changed due to different factors such as the type, age, growth characteristics, bamboo stalk positions, external environment and the like of the bamboo wood, so that the appearance size and various properties of the bamboo wood are obviously different, the utilization rate and the product performance of the bamboo wood can be reduced by mixing and utilizing the differences of the appearance size and the various properties of the bamboo wood without distinguishing, and the processing of the bamboo wood is also unfavorable, so that the classification of the bamboo wood is the key for determining the efficient utilization of the bamboo wood and the production of high-performance products.
