Information About Author:

Were measured spec1f1c methane fluxes that are representative for some peatland landscapes of Western S1beria forest-steppe. Spec1fic methane fluxes of forest-steppe eutroph1c m1res are very close to the same fluxes 1n subta1ga. Probability d1stribution of specific methane flux has following parameters: 1st quart1le/med1an/3rd quartile = 0.53/1.99/ 6.03 mgС GH4-m 2-h 1. Methane fluxes from bog lakes are close too, as in subta1ga they are estimated at tens and first hundreds of mgС GH4-m 2-h 1. Probability d1stribution of specific methane flux in riam: 0.00 / 0.09 / 0.21 mgС GH4-m 2-h 1. Annual methane em1ss1on from Western S1ber1a forest-steppe (estimated on the model Bc5) 1s 0.36 MtСH4/year that form 5 % reg1onal em1ss1on.
