SOME IMPORTANT PROBLEMS TO BE ADDRESSED IN RESEACH OF ACTIVE TECTONICS AND ENVIRONMENTAL DISASTERS IN CHINA

The active tectonics is closely related to environmental disaster.The geological disaster can be directly provoked by active tectonics, while earthquakes generated by activity of constitutions may derive a series of geological disasters.In addition,inappropriate activities of mankind can deteriorate the geological tectonic environment and aggravate the geological disasters.As for the study on the relations between active tectonics and the environmental disaster,the following four scientific problems should be addressed immediately: the zoning evaluation on the stability of China regional crust based on the modern continental dynamics;the uplift of Qinghai-Xizang Plateau and geological disasters;the engineering hazard of active tectonics and its prevention;and genetic mechanics of geological disasters by coupling the inherent and external dynamics.
