Informatization and big data play an important role in the sustainable development of agriculture in China.At present,China's agricultural informatization is widely used.In agricultural production,the cultivated land is constrained by natural conditions,and the conditions of fat and thin water resources are different.This results in a relatively single database in terms of content and functionality,and incompatibility between databases is poor.Standards cause the application of data not to be shared and sustainable.It is urgent to integrate and establish a database of agricultural resources to meet the needs of agricultural informatization.This paper analyzes the history and status quo of the agricultural resource information database.There is a small amount of data in the completed database,and there are no uniform standards and specifications among the databases,which results in a narrow application field and is difficult to update.In order to solve the above problems of the database,the standardization of agricultural resources database was studied,and the classification and coding of data were briefly described;the advantages and disadvantages were analyzed by comparing different database building platforms,and the management and editing of spatial data was understood even though MapInfo and MapGIS were used.There are advantages in terms of query,query,etc.,but there are limitations in large database management and sharing.ArcGIS has a full range of powerful GIS features that make up for the inadequacies of MapInfo and MapGIS and has good compatibility.This article analyzes the content and logical structure design of the agricultural resource information database in detail,uses the personal Geodatabase as the data storage model of the spatial database,and uses the Access database to manage the attribute data effectively.The preparation of source data and related data is closely related to the technical route for building the database,and then the sampling point information in soil testing and fertilization and the land ownership information in the database of rural land contractual management rights are collected.ArcGIS editing system is used for data collection.The editorial processing of the detailed description of the contents of the layer and the detailed design of the attribute field,the method of constructing the agricultural resources information based on the ArcGIS platform,the data quality control,and the demonstration and implementation of the construction of the agricultural resource information database.
