The concept of a natural morphogenic geoecosystem was used to model the vegetation in the GIS environment. The edaphic factors used in modeling included landform elements characteristics (slope and concavity/convexity) as well as the soil and the parent rock properties that define drainage. The climatic factors influencing the distribution of the vegetation embraced annual sums of precipitation and of active temperature. The information about the ecological interrelations between the factors and the vegetation was taken from the regional literature as well as from the field observations. Key words: Ukrainian Carpathians, potential natural vegetation, natural morphogenic geoecosystem.

Pollen productivity еstimate (PPE) and relevant source area of pollen (RSAP) are critical parameters for quantitative interpretations of pollen data in palaeolandscape and palaeoecological reconstructions, and for analyses of the landscapes evolution and anthropogenisation as well. In light of this, the present paper endeavours to calculate PPE of key plant taxa and to define the RSAP in the Kamchia River Downstream Region (Eastern Bulgaria) in order to use them in landscape simulations and estimations. For the purposes of this research, a dataset of pollen counts from 10 modern pollen samples together with corresponding vegetation data, measured around each sample point in concentric rings, were collected in 2020. Three submodels of the Extended R-Value (ERV) model were used to relate pollen percentages to vegetation composition. Therewith, in order to create a calibrated model, the plant abundance of each pollen type was weighed by distance in GIS environment. The findings led to the conclusion that most of the tree taxa have PPE higher than 1 (ERV3 submodel). Cichoriceae, Fabaceae and Asteraceae have lower PPE.
