Abstract

The invention discloses a method for establishing a comprehensive agricultural environmental information database. The comprehensive agricultural environmental information database comprises four sub-databases, i.e. a general attribute sub-database, a space sub-database, a video and audio sub-database and a model sub-database. The general attribute sub-database stores and manages agricultural environmental information attribute data through arranging a two-dimensional datasheet in a relation database management system SQL server. The establishment method of the space sub-database comprises that effective storage of space data in a relation database is realized through a space database engine and management logic is created through SDE in a classifying and layering way. The invention has the advantages of the practicability is high, the pertinence is high, the universality is good and powerful information support is provided for the comprehensive integration application of agricultural information.

Description

technical field [0001] The invention belongs to the technical field of computer and agricultural information integration, and relates to a method for constructing a comprehensive agricultural environment information database. technical background [0002] Environmental information system is the product of the combination of environmental science, computer technology science and information technology science. Database technology, as the underlying data management platform technology of environmental information system, has laid a solid foundation for the development of environmental information system. At present, there are some substantive deficiencies in the development of comprehensive agricultural environmental information databases at home and abroad, which are manifested in: the format of the input data is different, the data encoding is not complete and unified; the data abundance is insufficient, and the degree of data integration is low; the database construction sch...
