The invention provides a cross-linked sodium hyaluronate hydrogel material, which is good in tissue compatibility, high in strength, good in breathability and high in exudates absorbing capacity, and has certain transparency. According to the cross-linked sodium hyaluronate hydrogel material, with a sparse fiber mesh structure as a framework, the cross-linked sodium hyaluronate gel is combined with the sparse fiber mesh structure, so as to form hydrogel with a similar armored concrete structure; the hydrogel is formed by crosslinking the sodium hyaluronate and combining with phosphate buffer saline; and the phosphate buffer saline contains a bacteriostatic agent. According to the hydrogel with the structure, the characteristics of the sodium hyaluronate hydrogel are kept; and the strength and the toughness of the sodium hyaluronate hydrogel are increased.
