However, the information systems are still independent of each other, which posing obstacles to the application of natural resources. Based on enterprise service bus technology, Guangdong approval system of construction land is taken as a case to study the application patterns of natural resources in the province-city-county levels. The methods, design and work patterns of the technology are comprehensively explored for promoting technology application.
