摘要：The water balance of Zala County was analyzed using remote-sensing based actual evapotranspiration (ET A ) and runoff (R) in the context of land cover types. The highest mean ET A rates were determined for water bodies (658 mm/year) and wetlands (622 mm/year). Forests have higher values than agricultural areas, and the lowest rates belong to artificial surfaces. Mean annual runoff is the largest on artificial surfaces (89 mm/year). For climate change impact analysis a Budyko- model was used in spatially distributed mode. The parameter of the Budyko model (α) was calculated for pixels without surplus water. For the extra water affected pixels a linear model with β parameter (actual evapotranspiration / pan evapotranspiration) was used. These parameters (α and β) can be used for evaluating future ET A and R in spatially distributed mode. According to the predictions, the mean annual evapotranspiration may increase about 27 mm while the runoff may decrease to one third of the present amount by end of the century
