| Abstract: | The system design method of dataflow-oriented was applied to land suitability evaluation based on the introduce of dataflow-oriented design method in this paper. Through the data analysis of land suitability assessment system, this method obtained the data flow model of the land suitability assessment system namely multilevel data flowchart. Based on the data analysis results of land suitability assessment system, it then got the system structure drawing by structure design. Based on the system structure, it finally realized the land suitability assessment system. Through the dataflow-oriented design method, it improved the efficiency and accuracy of land suitability evaluation. |
