| Abstract: | On the basis of 1970—2006 leveling observations,we obtain the vertical velocity field of the west Qinling tectonic belt with the method of the least square adjustment.The results show that Liupanshan and its surrounding areas are rising with the rate 2-3 mm/a relative to Baoji benchmark(Longbao17) and the nearby Lanzhou basin area shows a subsidence trend,with the average rate 1.5 mm/a. |
