Uplift and the environmental disastrous effects in Qinling mountains

The Qinling mountains streches fromeast to west in the central part of China,and separates it into two parts: the North and the South,in geograph,geology and biology.Its large amplitude uplif thas been one of the most striking geological events in eastern China since the Late Mesozoic.The uplifting problem of Qinling range has made progress,however,several aspects of the problem such as the uplifting time,the uplifting speed and the uplifting amplitude had differences of opinion among the researchers.The previous studies demostrated that the main large amplitude uplif thas taken place in the Qinling mountains since the Cenozoic Era.This paper has stated several aspects of the research results about the uplift's amplitude and speed of Qinling range.According to the sedimentary response about the Cenozoic of the Weihe River basin,the author puts forward some results about the uplift of Qinling mountains.Based on the previous studies,this paper states the climatic and disat rous effects of the uplift in Qinling,the climatic effects reflect the fluctuations of air temperature and the variations of rainfall,the disatro us effects include soil erosion and water loss,earthquake and ground fissures in studied areas,also considered that the basic reason was the uplifting Qinling led to the climatic and disatrous effects.Through summing up the climatic and disat rous effects,it can provide scientific basis for the disaster control in the future.
