Abstract: In view of the fact that fields of grassland plots are so rich, there are many logical conditions that need to be set for inspection, and the workload of manual inspection is large, based on C# programming language and Aspose.Cells software development kit, the logic inspection software for grassland monitoring sample plot is developed. The software can check logical conditions in the table and logical relationship between tables, such as natural grassland sample plot table, plot line table, observation plot table, observation of small plant table, production measurement plot table, production measurement of small plant table, large grass and shrub table, and large grass plant survey table. The software has been applied to inspections of grassland plots in the southwest monitoring area. Applications show that the software can greatly reduce the workload of office work and improve work efficiency. The implementation of software can not only solve the existing problems in the current work,but also provide reference for the implementation of similar software programs.
