In the past, different historical periods had different important missions and, as aresult, the work of surveying and monitoring of natural resources elements of Guangxi was organized by different administrative departments. In the past, the China's natural resources were managed separately. the survey and monitoring of each element are organized and managed separately by land resources department, water resources department, agriculture department, forestry,department and marine department, etc. This led to the existence of many problems, such as multiple sources, different criteria, contradictory results and difficult share. For the purpose of solving these problems, all elements of natural resources in Guangxi need to be surveyed and monitored uniformly. The construction of a system for surveying and monitoring can provide an accurate, reliable, scientific and authoritative basic data for the registration of realestate of natural resources, the land space planning and use control, and the protection and remediation of ecological environment, etc. Starting with the theory system, the authors found the approach suitable for the situations in Guangxi and highlighted the effect of emergency monitoring. Then the architecture of cloud platform was studied and discussed, which included the multidimensional-stereoscopic observation network, the cloud computing of remote sensing big data, and the shared service of the data and results. Meanwhile, the key technologies of the system construction were analyzed. Finally, the prospect of survey and monitoring results-based applications was predicted.
