Regional specificity of the transformation of the water balance structure during restoration successions in the cutting of dark coniferous forests of the Yenisey Ridge

The paper discusses the features of the transformation of the structure of the water balance in the dark coniferous forests of the Yenisey Ridge, disturbed by logging. Questions of evapotranspiration dynamics are considered, considering reforestation successions in the cut areas. Based on the use of satellite data (MOD16A2), the change in evapotranspiration was analyzed considering the disturbance of the forest cover in the watershed. Against the background of the general dependence of evapotranspiration on meteorological parameters, the results showed that at the basin level, the variation in evapotranspiration depends on the accumulative effect of forest cover disturbance in the watershed. The ranking of felled areas, considering the regenerative-age dynamics of the vegetation cover, made it possible to assess the contribution of various stages of the reforestation process to the total evaporation in the Suhoy Pit River basin, and to reveal how the ratio of logging sites of the current year to the areas of already afforested cutting areas affects the amount of total evaporation. Studies have shown that if less than 2% of the total watershed area is deforested, then the logging does not cause major change in evapotranspiration and river runoff.
