Abstract:
      The response sensitivity of climate in Loess Plateau in China to global change was investigated with the meteorological data during the recent 40years，and the marked change points were calculated by Petitt method，and checked by moving T-test．The results showed that the sensitivity areas of responses of precipitation，temperature，soil-aridity and climate-productivity were mainly concentrated in around the middle part of Loess Plateau By using wavelet analysis，about2～4years period was verified for the change of sensitivity areas.
