The invention discloses a method for preparing a biological activity nanometer structure with the bacteriostatic action on the surface of pure titanium. The method comprises the following steps that sand blasting and acid etching are conducted on the surface of the pure titanium, and the hydrothermal reaction treatment is conducted. After the prepared sand blasting and acid etching titanium surface is subjected to the hydrothermal reaction treatment, a layer of zinc-doped nanometer particles are generated on the basis of an original micron-level surface structure, and a micro-nano composite structure is formed. Meanwhile, the shape of the zinc-doped nanometer structure can be regulated and controlled by changing the hydrothermal reaction time and concentration, and the surface has better biological activity and can be used for bone pegs and implants of the department of orthopaedics and the department of stomatology. 本发明公开了种在纯钛表面制备具有抑菌作用的生物活性纳米结构的方法，包括以下步骤：喷砂酸蚀纯钛表面、水热反应处理。所制备的喷砂酸蚀钛表面通过水热处理之后，在原有微米级表面结构的基础上生成了
