Design And Implementation Of Mineral Reserve Information Service System Of Jiangxi Province Based On Cloud Computing

National security,stability and rapid economic development are inseparable from the effective support of mineral resources.A sustained and stable supply of mineral resources plays an important role in national resource security and economic development.In order to fully grasp the supply capacity of China’s mineral resources,ensure the long-term stability of the country,and reserve sufficient mineral resources for the country’s medium and long-term development in advance,it is necessary to make an in-depth analysis of the mineral lands available for reserve in China,so as to provide decision support for the scientific utilization of mineral resources.Faced with the problems of large amount of geoscience multivariate and heterogeneous data,wide coverage of specialties,information distribution and high computing requirements,the frontier information technologies such as cloud computing and big data are used to build a mineral land reserve service system,and Jiangxi Province is taken as an example to carry out the experiment.The main research contents and progress of this paper are as follows:（1）A platform framework based on cloud computing is designed.Based on the basic environment of geological cloud platform,guided by the concept of "everything serves",this paper constructs the management and information service framework of China’s mineral land reserves（including reserve ore producing areas and reserve exploration areas）based on cloud computing,and designs a mineral land reserve data model that can manage structured / unstructured,spatial and attribute data.（2）The evaluation index and evaluation model are constructed,and a set of evaluation system suitable for the reserve data of ore producing areas is designed.After experimental calculation and comparison with the actual results,it is consistent with the actual results.It is suitable for the selection and evaluation of mineral land reserve data in the warehousing system.（3）Based on Hadoop big data platform,manage diversified and heterogeneous mineral reserve big data,supplemented by structured database to manage information resources,publish spatial data services in map server,and develop online mineral reserve information service system based on Web GIS.（4）Taking the tungsten reserve and exploration area of Jiangxi province as an example,it realizes the spatial data fusion and display,the attribute data management of reserve mine origin and reserve exploration area,the big data management of reserve mine origin and reserve exploration area,and the statistical analysis of mineral reserve data.It realizes the organic integration of structured and unstructured reserve big data,which has certain operability and practical value.The system has been deployed in the central geological exploration fund management center of the Ministry of natural resources,and has begun to integrate mineral land reserve data management and services in other 12 provinces in China.
