Flood risk in plant production
1986
Mietki, Z. (Akademia Rolnicza, Poznan (Poland))
In the article the author presents figure characteristics of the flood risk in plant production in the dynamic and spatial aspects. There were calculated indices of frequency and spatial range of floods as well as qualitative losses and intensity of destructions, caused by this disaster. On the ground of the obtained results it was stated that the flood risk was characterized by a considerable spatial and dynamic differentiation. The frequency of this event and its territorial range depends to a large extent on the presence of open water reservoirs and water courses, as the highest losses occur in plants cultivated in their close vicinity, i.e., on meadows and pastures. The average value losses in plant crops are not too high, in years of great intensification of that risk, their extent may clearly affect the country scale, as they reach 1% of total plan production. The problem of losses always occurs in the regions most afflicted with floods, because in those terriories over 50 percent of0699cultivated plant crops are destro
