The present invention relates to a three-dimensional porous tissue engineering carrier material, its preparation and application. Said three-dimensional porous tissue engineering carrier material includes three-dimensional porous structure, its internal porous structure is uniform, three-dimensional through degree is above 90%, pore size is 50-500 micrometer and porosity is 65-90%. Its preparation method includes the following steps: using polyhydroxybutyrate valerate (PHBV) and polycaprolactone (PCL) as raw material, mixing them, melting and spinning to obtain fibre whose diameter is 10-500 micrometer, cutting said fibre to make said fibres have identical length, making said fibres be uniformly arranged and filled into a mould, sealing said mould for 5min-1n at 50-80deg.C, demoulding, sterilizing and packaging so as to obtain the invented product. Said product can be used for repairing or reconstructing some tissue organs.
