Abstract:: In order to comprehensivly understand soil erosion in Gannan navel orange orchards, and provide a scientific basis for decision-making for the government, this article investigated the soil erosion in Gannan navel orange orchards based on field survey and statistical analysis. The results show that the total area of soil and water loss in Gannan navel orange orchard is 109 700 hm², accounting for 92% of the total area of the orchard, 53.92% for mild erosion intensity, 33.62% for moderate erosion, 12.46% for the intensive erosion, indicating that mild and moderate erosion was the major erosion pattern and mainly occurred in the orchards with more than 3~7 years and 7 years, soil and water loss in the orchard of 1~3 years is intensive, the loss rate was up to 3.602 million tons, erosion area was divided into 5 kinds. Xinfeng belongs to area with the least average erosion modulus, Chongyi belongs to area with the greatest erosion modulus.
