Zusammenfassung:A low pollution combustor and combustion control method therefor. The low pollution combustor comprises a combustor dome (12), the combustor dome (12) comprises a main combustion stage (14) and a pre-combustion stage (15), and the main combustion stage (14) and the pre-combustion stage (15) are arranged together in a concentric manner; the pre-combustion stage (15) is in the center, and the main combustion stage (14) is arranged on the periphery of the pre-combustion stage (15); the main combustion stage (14) comprises a main combustion stage channel, a main combustion stage swirler (30) provided in the main combustion stage channel, and a pre-film plate (31); the pre-film plate (31) is divided into an outer-layer pre-film plate (31b) and an inner-layer pre-film plate (31a) in a radial direction. A position and a spraying direction of a fuel spaying point (25) of the main combustion stage (14) are configured to control main combustion stage fuel to be sprayed into the main combustion stage channel by means of
