Abstract： The unique Danxia landform in the eastern partof Fujian province has created Mount Wuyi Scenic Area and Wuyi Zhengyan TeaProduction Area.Studying the characteristicsof soilerosionintheareahas important scientific significance for waterand soil conservation in the scenic spot.Based on the Erosion Productivity Impact Calculator （EPIC）model and random forest interpolation method， the K value of soil erodibility was estimated. The distribution of K values in the 0～200cm soil layer depth was analyzed，revealing the potential risk of erosion not covered by conventional shallow research.

Keywords：soil erodibility K value; spatial distribution characteristics;Mount Wuyi Scenic Area

土壤侵蚀是全球性环境问题，如土地资源退化、土地生产力下降、面源污染加剧、生物生境破坏，对物种多样性和人类生产生活的安全造成了威胁[1-2]。（剩余3699字）
