The invention relates to an identification method of aromatic amino acid isomerides DL-m-tyrosine (meta-hydroxylphenylalanine) and L-tyrosine (p-hydroxylphenylalanine). The identification method is characterized in that a 'H2SO4-NaBrO3-[CuL](ClO4)2-malic acid' nonlinear chemical oscillation system is used as identification solution, and according to different inhibition time generated for the system by the tyrosine isomerides, identification on the tyrosine isomerides is further implemented; in [CuL](ClO4)2, L is 5,7,7,12,14,14-hexamethyl-1,4,8,11-teraazamacrocycle 14-4,11-diene. An oscillation map provided by the identification method provided by the invention has intuition; the amino acid isomerides DL-m-tyrosine and L-tyrosine can be conveniently and rapidly identified; moreover, the identification method adopts simple equipment, and is high in accuracy and easy to operate and observe. 种芳香族氨基酸同分异构体DL-m-酪氨酸（间羟基苯丙氨酸）和L-酪氨酸（对羟基苯丙氨酸）的鉴别方法，其特征在于：应用"HSO-NaBrO-[CuL](ClO)-苹果酸"非线性化学振荡体系作为鉴别溶液，根据酪氨酸同分异构体对该体系产生的抑制时间不
