摘　　要：很多种木材细胞中都含有二氧化硅、草酸钙、碳酸钙等无机晶体,这些无机物质在木材中起到了提高木材物理力学强度,克服木材自身缺点(如易腐、易燃、尺寸不稳定等)的作用,在结构上这些无机物质与木材本身构成了一种天然复合材料,即木材-无机质复合材料。生物矿化研究以活立木为对象,为木材生物改性和新材料开发提供了新思路。要实现木材-无机质生物矿化复合材料的人工模拟,关键是研究木材中无机硅等的含量情况以及生物矿化所形成的木材-无机质复合材料的形成机理。本文主要对生物矿化木材中矿物质的含量情况进行探讨,并提出今后的研究方向。There are many tree species of which wood cells contain crystals of a few inorganic matters such as silicon dioxide, calcium oxalate,calcium carbonate, etc,These inorganic matters play a role in improving the physical and mechanical proprerties of wood as well as in overcoming some limitations of wood such as weak resistance to decay, flammability, dimension instability, etc. In structure, the wood itself and these inorganic crystals constitute a type of natural composite materials, wood-inorganic composite materials. The biomineralization research of wood takes living standing trees as its objects.This opens up a cut-in point for simulating the natural biological wood modification to develop a new kind of materials. The key to realize the simulation is to reveal the content of silicon and other inorganic matters in wood and the formation mechanism of wood-inorganic composites by biomineralization. In this paper, previous studies on content of silicon and other inorganic matters in natural biomineralized wood by tree species and by tree parts are reviewed, and main directions for future research as also suggested.
