Abstract:: In order to analyze the distribution characteristics and the key impact factors of the Benggang erosion in Ganzhou City，based on the general data of Benggang，a landslides database was constructed. The gray correlation degree method was adopted to analyze the function of each factors includeing altitude，slope，slope direction，slope type，soil parent material，soil type，rainfall erosion force，distance from river，vegetation coverage and land use type. The results show that: Benggang in Ganzhou City mainly distributes in Longnan County，Ganxian District，Yudu County，Xingguo County and Shicheng County，with a total number of 17 917，accounting for 55.34% of the total; there are 10 counties and urban areas ranking first in topographical factors(elevation，slope and aspect)，8 counties and urban areas ranking first in hydraulic factors(rainfall erosion force); topographical factors and hydraulic factors have the strongest influence on Benggang erosion in Ganzhou City. The impact factors of Benggang erosion in Ganzhou have location particularity，therefore，the targeted prevention and control measures should be taken in the process of prevention and control of Benggang erosion.
