Zusammenfassung:	The invention relates to a zero emission method for comprehensive utilization of tree branches and leaves through gasification and anaerobic fermentation, and belongs to the technical field of comprehensive utilization of tree branches and leaves. The technical scheme is as follows: livestock and poultry manure as a material is added into biogas slurry, stirred and fed into an anaerobic fermentation tank (7); tree branches and leaves serve as raw materials and are put into the roller dryer (1) to be dried and enter the fixed bed gasifier (3) to be gasified, and generated wood gas enters the anaerobic fermentation tank (7); marsh gas generated in the anaerobic fermentation tank is desulfurized and then enters a steam turbine (9) for power generation; after being sterilized (11), the biogas residues are mixed with plant ash discharged from the fixed bed gasification furnace to serve as solid organic fertilizer. According to the invention, the wood gas generated by wood gasification is used for increasing the me
