The study of carbon dynamics and light reflection features of tree species in forest-steppe zone of Western Siberia

The work presents research materials of the dynamics of carbon dioxide exhalation by soils of forest bio-geocenoses of the park of the Omsk Agricultural University, showing absence of the influence of tree species on the contribution to the total emission of CO2 from the soil. When measuring the carbon dioxide exhalation the humidity and temperature of the soil were taken into account, according to this we can conclude about the absence of the influence of these factors on the soil “breathing”, however in seasonal dynamics when the temperature and humidity falls, also carbon dioxide emission reduces. Also, the main parameters of timber stand are measured; diagrams of interrelations of height and diameter of explored trees are constructed, that say about the reliability of empirical data. The mathematical treatment with the identification of correlations has been done. The determination coefficient ranges from 0.860 to 0.937. According to the main parameters of the timber stand the amount of biomass was determined, that affects the reflectivity of plant facilities. The works of native and foreign scientists in the field of different resolutions multispectral images decoding for monitoring of forest fires, for detecting of illegal logging of forest plantations, for determining of the rock composition in the mountain and hilly terrain are widely known. This work presents first data devoted to studying of the possibility of high spatial resolution satellite images using КА WorldView-2, for decrypting the coniferous and deciduous species of Western Siberia forest-steppe zone. We studied the nature of the absorption of short-wave and long-wave part of solar radiation spectrum, that showed different species absorb different amounts of solar energy, the greatest difference was observed in the satellite image synthesis based on infrared shooting range.
