The Data Platform of Resource and Environmental Science is a foundation of data and model simulation for geography research, and the data mainly comes from several field observation stations in distributed location, spatial observation data such as MODIS and some data service site such as USGS of internet. The data collection, management, assimilation and the service of share is a main task of the Data Platform. According to the distributed characteristic of the data source dispersion and the service object and new technology of the Grid environment, in this paper we discuss the foundation of the Data Platform of the field observation stations' Resource and Environmental Science, and the process framework of the data gathers with the management, and defined and analyzed the key functions and implementary techniques for each module. Base on simulated the environment of the field observation stations in Linux operation system, we validate some functionality test about the key techniques and pathway for data replication, data synchronization and a uniform data service in data platform, and using acquired some techniques to build a primary Data Platform of the field observation stations' Resource and Environmental Science on Grid environment.
