Миронычевой-ТокаревойТомск201713Because of the methane having greenhouse effect, the wetlands have been studied rather inten-sively as sources of methane as well as forests have been studied like methane sinks (Glagolev et al., 2012; Fedorov et al., 2015; Sabrekov et al., 2015). The ecosystems of periodically flooded for-ests have been studied substantially less, although there arises more questions. The major question is what the periodically flooded forests are: sources or sinks of methane. Currently the Standard Model doesn’t consider the flooded forest at all for the calculation of the methane flux from the Western Siberia territory (Глаголев, 2008). If the flooded forests periodically produce methane it may sufficiently change the regional flux estimation In connection with this, the aim of our study VARIABLE REGIME OF METHANE EMISSION IN PERIODICALLY FLOODED FORESTA.I.

The measurements were conducted by the static chamber method as described in (Sabrekov et al., 2015).The results of the individual measurements are shown in the Table 2, 3. The obtained me-dians of the methane fluxes was 0.048 mgC·m-2·h-1 for wetland forest near the river Polynanka and 0.602 mgC·m-2·h-1 for wetland forest near the Bakcharskoe bog. The typical fluxes of the Bakcharskoe bog were 0.275 ё 5.449 mgC·m-2·h-1  in the open bog and 11.673 ё 62.943 mgC·m-2·h-1 in the paludal lake. It is shown that a huge rain causes a significant increase of the water table level which may turn soil methane uptake (usually relatively dry conditions) into emission (typical for wetlands) rather fast (time ~ hours÷day). Most probably it can be explained by the hypothesis that increasing of soil moisture observed after rain (intensification of anaerobiosis) not so much acti-vates the methanogenic archaea as cuts off the methane-consuming “filter” supplied by the activity of the methanotrophic bacteria. 1.
