The analysis and the classification of a mass of characteristic data which has been accumulated for nearly forty yeare through the research of cold and arid regions natural resources, ecological environments, engineering and economic growth were made based on the natural background of the cold and arid regions in China and the research on this special environment. We classified the data resources according to the characteristics of cold and arid research and introduced them according to the classification. For the convenience of data acquisition and data application, we classified the professional characteristic database according to its form: relation data, spatial data, binary and text data, into three-level database group structure which constituted the characteristic database of cold and arid regions resources and environments research. According to the characteris tics and the origin of these data sets, the metadata of cold and arid dataset should be described by six sections, that is, identifier information, collection information, description information, management information, access information, supplement information. The data sharing and data efficient application of the cold and arid characteristic database were discussed from two aspects: the sharing mechanism and the sharing technical platform. The sharing mechanism was given and a few main factors that effected the data share were explained. On the basis of the present data sharing services, as for how to improve the data sharing range and data utilization efficiency based on high-performance computing and network environment, and how to provide good data sharing services, we carried out the data platform construction based on data and application of cold and arid resources and environments research, the remote computing based on the Web and data grid technical trial work.The progress of the work was discussed briefly.
