摘要：Research concerning agricultural drought issue mainly focuses
on the methods based on long-term atmospheric data, temperature,
precipitation and evaporation measurements. On the other hand, the
scientific bibliography shows the possibilities of using spectral data for
description the state of plants. The general availability and increasing
resolution of the spectral and temporal data create a chance for monitoring
and forecasting deficiencies of soil moisture based on spectral images.
Paper presents the results of analysis of the moisture conditions in soilplant
environment in the lowland catchment area using the spectral data
obtained from the Sentinel-2 European Space Agency satellite for period
February-November 2016. These spectral data were used for the
calculation the Normalized Differential Vegetation Index (NDVI) which
provided information about moisture conditions in the soil-plant
environment. Then, the values of NDVI index were compared with the
data obtained from the field investigations. The analyses have showed the
spatial and temporal variability of moisture conditions in the soil-plant
environment determined on the background of the spectral indicators and
the existence of some dependences between climatic and spectral
indicators characterizing soil-plant environment.
