The key of remote sensing supervision and management of production and construction projects is the establishment of interpretation mark database.In the process of establishing interpretation mark database,there are many problems,such as different remote sensing image characteristics of the same type of projects or the same remote sensing image characteristics of different types of projects.Taking Jiangxi province as an example,this paper puts forward the result classification database based on the previous geometric feature analysis,color analysis,location analysis and surrounding land class composition analysis,and carries out the hierarchical classification feature extraction of reclassification according to the significant differences of different production and construction project types,so as to infer the production and construction project types of the interpreted target features.The research of this method can provide key constraints and discrimination support for the establishment of remote sensing image interpretation mark database of soil and water conservation in production and construction projects.
