The invention discloses a method of preparing a thermal barrier coating ceramic layer of a quasi-column structure through plasma evaporated deposition, and belongs to thermal barrier coating materials and the preparation field. The ceramic layer of the quasi-column structure is a polycrystalline columnar structure coating formed by depositing solid phases, liquid phases and gaseous phases, and the material of the ceramic layer of the quasi-column structure can be yttria partially stabilized zirconia (YSZ) and lanthanide series zirconate or cerate. A thermal barrier coating comprises a bonding layer prepared on a base body and the ceramic layer of the quasi-column structure, and the ceramic layer is a single-layer YSZ coating or double-layer YSZ and lanthanide series zirconate or cerate coating. The ceramic layer of the quasi-column structure can be prepared through the plasma evaporated deposition method. The ceramic layer of the quasi-column structure has the advantages that the deposition rate is high, the
