英文摘要：

The network measurement is of great importance to the QoS of space communication network. A new space path capacity measurement method and a novel visualization technique of measurement results called ＂dynamic radar graphic＂ are proposed in this paper. The accuracy and efficiency of the methods are proved in the simulated space network platform.
