| Zusammenfassung |
In Hungary, wind erosion is one of the most serious natural hazards. Spatial
and temporal variation in the factors that determine the location and
intensity of wind erosion damage are not well known, nor are the regional
and local sensitivities to erosion. Because of methodological challenges, no
multi-factor, regional wind erosion sensitivity map is available for
Hungary. The aim of this study was to develop a method to estimate the
regional differences in wind erosion sensitivity and exposure in Hungary.
Wind erosion sensitivity was modelled using the key factors of soil
sensitivity, vegetation cover and wind erodibility as proxies. These factors
were first estimated separately by factor sensitivity maps and later
combined by fuzzy logic into a regional-scale wind erosion sensitivity map.
Large areas were evaluated by using publicly available data sets of remotely
sensed vegetation information, soil maps and meteorological data on wind
speed. The resulting estimates were verified by field studies and examining
the economic losses from wind erosion as compensated by the state insurance
company. The spatial resolution of the resulting sensitivity map is suitable
for regional applications, as identifying sensitive areas is the foundation
for diverse land development control measures and implementing management
activities. |
