The invention belongs to the macromolecule material technology field, which relates to a preparation method of biodegradable and bio-absorbable macromolecule nanometer fiber non-woven fabric material, in particular to the preparation method of natural high polymer biological material, namely, sodium alginate electrostatic spinning solution, and the preparation method of pure sodium alginate nanometer fiber membrane material. The preparation method and the technical principle of the invention comprise the following steps: aiming at the characteristics of rigidity and stretching ability of the sodium alginate molecular chain in the aqueous solution, a solvent type strong polar modifying agent, namely, polyhydroxylated compound is induced in the aqueous solution of the sodium alginate, and through the strong polarity and the low surface tensile force, etc. of the compound, the physical property of the aqueous solution of the sodium alginate is effectively adjusted, thereby realizing that the transforming from th
