Abstract:In order to dynamically monitor soil erosion and determine the relationship between landuse and soil erosion in Baota District of Yan'an City,an analysis was performed using the data from TM images in the two periods of 1997 and 2004.Results show that soil erosion occurred in cultivated land,forestland,grassland,and orchard.The area of cultivated land decreased and the areas of woodland,grassland,and orchard increased from 1997 to 2004.The area of soil erosion decreased and its grade descended.Generally speaking,landuse and soil erosion control in the study area develop towards a good direction.
