The Qinling Mountains stretches from east to west in the central part of China, and separates it into two parts: the North and the South, in geography, geology and biology. Its large_amplitude uplift has been one of the most striking geological events in eastern China since the late Mesozoic, the study of the uplift stages and amplitudes of the Qinling Mountains is helpful to understand profoundly such important problems as the present climate, geology, geography and zoology of China. It was well known that Qinling became land and was uplifted at the end of the Triassic, however, the uplift amplitude was limited, the previous studies demonstrated that the main large_amplitude uplift has taken place in the Qinling Mountains since the Cenozoic era. Based on those studies, through the tectonic uplift′s character and pattern, the planation surface′s evolution, the sedimentary response, the uplift′s amplitude and speed, the stream structure and river terraces and so on, this paper has stated several aspects of the research results about the tectonic uplift of the Cenozoic era in Qinling, the author considered that, so far, the research need to study further. To strengthen the studies about the formation and evolution of the Weihe River basin is the key to the settlement of the question about the uplift history of the Cenozoic era in Qinling.
