The invention discloses a management object-oriented natural resource data fusion system. The natural resource data fusion system comprises a control module, a data classification module, a data bloodrelationship analysis module, a data use object analysis module, a spatial information comparison module, a spatial fusion module, an element materialization processing module, an element attribute fusion module and a service data fusion module. Wherein the control module is respectively connected with the data classification module, the data blood relationship analysis module, the data use object analysis module, the spatial information comparison module, the spatial fusion module, the element materialization processing module, the element attribute fusion module and the business data fusionmodule; firstly, natural resource management objects are sorted out, and existing natural resource current situation data, planning data, management data and social and economic data are divided intocurrent situation data, management unit data and business process data from the perspective of the natural resource management objects. According to the invention, the problem of multiple counting doors is solved, natural resource management is better served, and data fusion development is realized.
