Abstract

Supported by remote sensing and GIS technology, the authors quantitatively evaluated the volume of soil

loss and the soil loss intensity in Xuanhua County in 2000 on the basis of RUSLE model, and made a characteristic

analysis of the spatial distribution of soil loss in this county. The results show that the soil erosion area (with

the erosion stronger than mild erosion) of Xuanhua County in 2000 was 982.85 km2, accounting for 39.25% of the

total area of Xuanhua County. The average soil erosion modulus was 13.92 t•hm-2•a-1, belonging to mild erosion. The

steeper the slope, the more probably the strongest erosion happened. On the whole, the slope belt of 15°～25° was

the belt subjected to the largest proportion of eroson. Soil erosion in Xuanhua County is mainly concentrated on

the irrigation grassland and the dry land, and the soil erosion area of these two land types in Xuanhua County

accounted for 93.897% of the total soil erosion area in 2000.
