Based on the L1,L2 and L3 level data base plate of digital twin basin in smart water,and the basic and business data of water and soil conservation,focusing on the construction task of smart soil and water conservation digital scenes during the“14th Five-Year Plan”period,this paper proposes the objectives,overall framework, technical workfl ow and methods of water and soil conservation digital scene development,considering its application needs of digitization,networking and intelligence. This proposal can provide ideas and reference for smart water and soil conservation development. By promoting interactive application of digital twin,big data,artifi cial intelligence and other technologies with water and soil conservation business,the intelligent perception of information,effi cient coordination of management services,timely and eff ective supervision and law enforcement,and the pre-judgment plan of check dam operation risk have been realized. However,the development of digital scene is still in the initial stage and needs further exploration and improvement in practical application.
