A low-pollution combustor and a combustion control method therefor. The low-pollution combustor includes a combustor head including a primary combustion stage and a precombustion stage, the primary combustion stage including a primary-combustion-stage channel and a primary-combustion-stage swirler disposed in the primary-combustion-stage channel. The primary combustion stage includes a pre-film plate disposed in the primary-combustion-stage channel, and the pre-film plate is radially divided into an outer-layer pre-film plate and an inner-layer pre-film plate. The positions and injection directions of fuel jet points of the primary combustion stage control fuel of the primary combustion stage to be injected into the primary-combustion-stage channel through primary-combustion-stage fuel jet orifices; and part of the fuel directly forms primary-combustion-stage direct-injection fuel spray, and the other part is hit on the pre-film plate close to an inner side of the primary-combustion-stage channel, or the two parts are respectively hit on the two layers of pre-film plates.
