Through analyse of characters of China's earthquake and comparison of present technology conditions of the emergency rescue equipments in the domestic and international vital catastrophes. Based on “the project of the scientific research concerning Wenchuan 8.0 Earthquake Emergency Rescue”in China, the authors study sufficiently the various impediments factors to implement the earthquake catastrophe rescue on the aspects of technique and equipment in china. Furthermore, there are the following many considerations, for example, the communication command and management of the emergency rescue, the collection and transmission of the information from the rescue locale, the rescue and accessorial systems of the experts decision-making, especially, after the vital earthquake, the actions of searching lifes in the ruins, the rescue and safe protection suitable to the complex conditions of the landslides and the blocked traffic, the environment of the tumbled large building constructs and the small spaces in the ruins and so on. The basic technological equipment demands are presented to guarantee the effective rescue when a great earthquake occurs in China anywhere.
