- Abstract:
-
Wind erosion is one of the main ecological problems in the Xilinguole grassland. Road and residence have the important influences on wind erosion in grassland. However, this phenomenon has not been well considered or studied. In order to assess the influences of road and residence on wind erosion parameters, road and residence information was obtained by visual interpretation of remote sensing images, and they were overlaid with eight wind erosion parameters including categories of soil properties and vegetation cover. GIS methods such as extract by mask were employed to explore the influences of road and residence on wind erosion parameters. The results show that as the distance to road and residence decreases, vegetation coverage and height decrease, and soil water content, sand content and soil bulk density increase. The maximal influencing distance of the residence on parameters is 2 000 m, and that of the road is 400 m. Within the influencing distance, the variation ranges of the vegetation cover parameters are larger than those of soil property parameters, and the influences of the residence on parameters are stronger than those of the road. Road and residence increase wind erosion risk, therefore, they should be considered in the index system and models for assessment and estimation of wind erosion. These results can provide scientific references for wind erosion mechanism research and wind erosion prevention in grasslands.
