The present invention relates to bone repair material of multivariant amino acid polymer-hydroxyapatite, supportive implants and preparation method. Said restorative material is made of multivariant amino acid polymers consisted with ε-aminocaproic acid and other α-amino acids, together with constituents modified hydroxyapatite, in which the constituent modified hydroxyapatite uses calcium salt as modified constituents that can be accepted in medicine and has a more solubility compared with hydroxyapatite. Modified hydroxyapatite is constructed from said calcium salt and hydroxyapatite, with a mass ratio of (2-20):(98-80), and the content of modified hydroxyapatite is 10-70% based on the mass of said bone repair material; the content of ε-aminocaproic acid in multivariant amino acid polymers is 60-99% based on the total molar quantity of multivariant amino acid polymers.
