Methane fluxes from municipal solid waste landfills in Surgut and Khanty-Mansiysk are assessed in August 2015 by the inverse modeling method. It is revealed that the methane flux values vary from 0.3 to 5.8 g CH4/(m2 hour). The highest value of the methane flux is typical of a landfill that is currently used for the waste disposal and is not covered with the soil layer, whereas the lowest value was obtained for a closed small-capacity landfill covered with soil and vegetation. 相似文献

Methane emission from West Siberian forest-steppe and subtaiga reed fens (that is, fens dominated by Phragmites australis) observed in summer 2013, is considered using the static chamber method. The obtained medians of CH4 fluxes varied from -0.08 to 2.7 mg CH4/m2 per hour. Eenvironmental factors affecting methane emission are analyzed. It was found that CH4 emissions from the reed fens correlate only with the concentration of salt ions in the wetland water and with the plant community structure. The latter probably also depends on water salinity. It was revealed that in fens the ratio between fluxes of CH4 and CO2 does not depend on the water table level that contradicts the general pattern simulated by mathematical models of CH4 emission. It was found that Phragmites australis fens and similar ecosystems should be considered as a separate wetland class from the point of view of methane emission study. 相似文献

A typological map of wetlands in the southern taiga of West Siberia has been compiled based on high-resolution Landsat images. In accordance with the new map, the area of southern-taiga wetlands is estimated at 12.02 Mha at the total wetland area percentage in the subzone estimated at 28%. The final accuracy of determination of various wetland classes is 80%. The use of the new map improved the estimates of methane emissions from southern-taiga wetlands from 0.84 to 1.57 MtCH4/year, i.e., by 87%. The respiration of wetland ecosystems in the southern taiga of the West Siberia is estimated at 67 MtCO2/year. 相似文献
