Abstract: Network media plays an important reconstructive role in the dissemination and development of minority culture. The tracking survey of Yi Years network reports in recent years shows that the traditional culture of the Chinese minority nationalities is undergoing a gradual metamorphosis under the “microscope” of network media which includes not only a passive cultural reconstruction resulting from the network-intrigued cultural changes but also the visible on-net cultural appeal arising from cultural changes. The interactivity, openness and reconfiguration of cultural resources provide the minority culture with a much broader stage fodisplay, which has doubtlessly excited the enthusiasm for disseminating the native culture and at the same time, promoted inter-culture exchanges. By aid of network dissemination, minority culture undergoes a cultural reconstruction. Network media is both a challenge and an opportunity to the minority culture. On the one hand, the network media helps more media audience to better understand, disseminate and protect the minority culture; on the other hand, in the process of network dissemination, the essence of some minority culture has to bear the risk of being assimilated and finally reduces to a sign culture of symbolization.
