　　Abstract: Remote sensing monitoring is an important means of obtaining water resources information. However, the multiple sources of data, and heterogeneous algorithms and services have led to noticeable problems such as insufficient sharing of data and application. To manage these data and integrate numerous algorithms, a remote-sensing water resources monitoring platform for heterogeneous services can be established to synergize various resources. The platform applies KVM to virtualize underlying resources, efficiently stores and processes data through distributed file systems and data cubes, and shares them with the help of services encapsulation. Combining the remote sensing monitoring and statistical data of water resources shared by all levels of departments, the platform realize the sharing and exchange of remote sensing monitoring data and heterogeneous services of water resources in our country, using the architecture ascending with four layers, i.e, infrastructure, data, application and users. It has great potential in real-time monitoring and management of water resources in China.
