Absorption of Power Plants СО[sub]2[/sub] Emissions by Coniferous Tree Stands
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2015, Vol 11, Issue 4
Abstract
The article reviews the ability of coniferous (common pine, siberian larch and siberian spruce) stands growing in 9 municipal districts of the Irkutsk region to absorb СО[sub]2[/sub] technogenic emission of heat power plants. (EIGAF) index is suggested to characterize gas-absorbing (СО[sub]2[/sub]–absorbing) activity; the index reflects proportion between СО[sub]2[/sub] technogenic emission and photosynthetic productivity (GPP) of coniferous tree stands. СО[sub]2[/sub]–absorbing capacity in 8 of the monitored districts has been shown to significantly exceed the amount of carbon dioxide emission from heat power sector. The index values EIGAF=0.01-0.97 demonstrate that СО[sub]2[/sub] technogenic emission amounts to 1-97% of coniferous stands photosynthetic productivity in the areas under study. At the same time, the most industrially developed Angarsk district shows СО[sub]2[/sub] photosynthetic absorption to be 8-12 times lower than technogenic СО[sub]2[/sub] emission. Reasons of low gas-absorbing capacity of coniferous tree stands of this area are discussed.
