| Abstract | ||
| The variation Wind erosion of soil from place to another, cause the variation of variables affecting its activity, and the research aims to quantify the variables of wind erosion soil in governorate of Taiz, to reveal effect of each of them on wind erosion in governorate, was followed by revealing effect of all these spatial variables combined on wind erosion. , By building model by which all these variables were Merge according their weights. The research methodology was to collect data on each spatial variable related to wind erosion of soil, And processing this data, and deriving the informational layers for each spatial variable using a number of mathematical algorithms in the raster calculator for Arc Map 10.5, Highlighting effect of each spatial variable separately on wind erosion activity in governorate, In preparation for integrating all these spatial variables together by means of a model that shows suitability of soil for wind erosion in governorate according to the impact of all these spatial variables. The results of research found that area of district that was Described a high suitability for wind erosion is 4129.2 km2, or 41.22%, and the area of district that was Described moderate suitability for wind erosion is 2267.4 km2, or 22.63%, and area of district that was Described low suitability for wind erosion 2267.4 km2, or 22.63%, and the area of district that was Described by strong suitability for wind erosion is 461.9 km2, or 4.61%, and the area of district that was Described poorly suitability for wind erosion 275.2 km2, or 2.74% of total area governorate. | ||
