The investigation and evaluation data of reserved cultivated land resources are of great significance to the research and policy-making about cultivated land protection, it is necessary to establish stable and efficient information systems to manage and use the massive data. To this end, this article adopt a hybrid storage strategy, uses relational database, non-relational database and file database to establish the national investigation and evaluation database of reserved cultivated land resources. Automatic and parallel database building technology, spatial big data calculation technology and vector data dynamic rendering technology are researched on, which has solved the technical bottleneck of large-scale spatial data storage, management and visualization. On this basis, developed the database management system, it has been applied in the government administration of cultivated land resources in China and exerts positive results.
