生物矿化是活体竹材的生命过程的一部分，是在一个多层次的复杂系统中进行的动态过程，参与调控的化学因素、基质因素和细胞状态都是在变化之中的。在这个过程中，在活的竹材机体内是同时实现化学调控、基质调控和细胞调控三层次相互调控的过程，本项目主要研究这些调控层次上的变化是如何最终形成竹材表皮硬组织（竹硅化材料）的，竹材中生物矿物生长和形态发生机理，阐释竹材生物矿物复合结构-性质-功能的关系和有机多糖/无机硅之间的共存关系及界面特征，明确竹材生物矿化的作用类型。最终要揭示这三个层次之间的关系，阐释竹材生物矿化的机理，构建竹材生物硅化的理论基础。认识竹类的生物矿化及其形成机理，不但有助于更深入地揭示竹材的自然属性，而且有助于竹类基于生物矿化理论和仿生原理的竹质新材料的开发和利用，促进竹材的全竹利用、为竹青竹黄胶合提供理论依据，以及在智能设计、仿生结构材料学等高科技领域发挥重要作用。

Biomineralization is part of the life process of living bamboo wall. It is a dynamic process of a multi-level complex system in which the chemical factors, matrix factors and state of cells that participate in the regulatory process are constantly changing.Three-level mutual control of chemical regulation, matrix regulation and cell regulation of living bamboo is synchronously achieved in this process. The project mainly studies how the changes at these regulatory levels lead to the formation of the hard epidermal tissue (silicification materials of bamboo) of bamboo wall, the growth of biological minerals and morphogenesis mechanism of bamboo, and aims at illustrating the relationship among the biological mineral composite structure-property-function of bamboo, and the symbiosis and interface features between the organic polysaccharide and inorganic silicon, and identifying the types of biological mineralization in bamboo. Finally, the relationship among the three levels will be revealed, biomineralization of living bamboo interpreted, and the theoretical basis for biological silicification of bamboo constructed. Understanding the bio-mineralization and formation mechanism of bamboo contributes to further revealing the natural property of bamboo, also to the development and utilization of new bamboo materials based on the biomineralization theory and bionic principles, to promoting utilization of the entire bamboo plant, to providing theoretical basis for adhesion between the outer and the inner of bamboo culm, and to playing an important role in the relevant high-tech fields, such as the intelligent design, bionic structure materials and so on.
