Shevchuk N. Ecological functions and energy potential of forest plantations of Podolia in conditions of climate change

The thesis is devoted to the promotion of environmental functions (carbon sequestration and production of oxygen) and energy potential of forest stands of Podolia (for example, Khmelnytskyi region) in the context of climate change. Estimated modern state of oak forest plantations and climate change (temperature, humidity, precipitation) in the study region. The analysis of the dependence of the height and diameter with the age of the plantations and were compared with the standards in tables. Analyzed climatic characteristics of the study region for the period 1965-2015, and there was a trend of decreasing annual amounts of precipitation in 100 mm increase in mean annual temperature by 1.7°C, reducing the relative humidity by 2%. It is established that the climate in the region remains unchanged fresh piles (D2). Biometric indicators of the developed empirical equations with the definition of overground phytomass 8 species of trees, and their carbon absorbing oxygen and generating energypotential per unit area. Found that the greatest carbon absorptive capacity has a black alder, Linden alcolista, birch and 60-100 t/ha. Less ability to accumulate in the phytomass carbon is pine, ash and spruce. Among woody species, the lowest oxygen producing capacity have such species as black alder, common oak, common ash, Norway spruce, and the bigger - the birch of about 370 t/ha. Per unit area of the greatest energy potential are species such as the common ash, small-leaved lime, black alder, their capacity is ranging from 2.6 to 3.8 TJ/ha.
