Wind Erosion Hazard Assessment of Mongolian Plateau by Using FMC Fuzzy Cluster Method

The wind erosion environmental factors of Mongolia Plateau were derived and clustered using fuzzy clustering method(FCM,fuzzy c-means clustering),and then the knowledge of wind erosion-environment relationships was obtained through relating unique environmental combination classes to unique wind erosion type via the help of expert knowledge,finally the wind erosion hazard map was derived using the extracted wind erosion-environment knowledge and validated by remote sensing data of wind erosion intensity.The result indicated that wind erosion hazard became higher from south to west and from south to north in Mongolia Plateau and the approach is effective for obtaining wind erosion-environment relationship knowledge and predicting wind erosion mapping over areas without local wind erosion experts.
