The invention discloses a blockette multi-level inflation composite structure fabric, and relates to the technical field of textile materials and textiles. Four layers of fabrics with single surfaces are flatly arranged, and two adjacent layers are connected with each other through parallel connection belts (5 and 6); an inflation chamber is formed between two adjacent connection belts; the upper connection belt and the lower connection belt of the middle two layers of fabrics are parallel to each other and are staggered from each other at an interval; a first outer inflation chamber (20), a second outer inflation chamber (30) and an outer layer inflation channel (52) are communicated and are communicated with an outer inflation port (41); and an inner layer inflation channel (61) is retained in the inner layer connection belt (6), so that the inner inflation chambers (10) are communicated with one another and are also communicated with an inner inflation port (51). By four layers of fabrics for protection, the cold and heat isolation effect is enhanced; a multi-level adjustment function is realized; the thickness, the isolation performance or the floatage of the composite fabric can be changed; the use of the blockette multi-level inflation composite structure fabric cannot be influenced by local damage; and the blockette multi-level inflation composite structure fabric can be used as a tent material, a floatage device, human body protection or rescue auxiliary equipment and the like.
