ANALYSIS OF THE PHOTOSYNTHESIS OF AGRICULTURAL AND FOREST ECOSYSTEMS BY CHANGING EXTERNAL FACTORS BASED ON THE SATELLITE DATA

M.V. Vakolyuk

A main focus in this paper is made on possibility of using results of the remote sensing of the atmosphere and the Earth surface by Tanso-FTS sensor (GOSAT satellite, Japan) and MODIS sensor (Terra satellite (EOS AM-1)) accordingly. Qualitative and quantitative changes of the plant cover were analyzed by the use of mathematic calculation, visual analysis and plant cover classification map. Analyzed in the article are photosynthesis changes of the agricultural and forest ecosystems of Ukraine (Rivne and Zhytomyr regions) by taking into consideration naturally and climate conditions and plant cover types. Special accent was given to the analysis of СО₂ concentration changes on the territory of research.

Keywords: photosynthetic activity, concentration of СО₂ in the atmosphere, remote sensing, СО₂ fertilization effect.
