| The sensitivity of output index of different crops (wheat, corn, potato, panic, millet, flax, rape) to the large-scale climate variations was investigated by using the crop production data and the meteorological data of growing seasons (Apr.to Oct.) during the period of 1980～2000.The results show that the output of wheat, corn and flax was much sensitive to climate changes, and the sensitive area was mainly in Hexi region, but the Loess Plateau region was less sensitive;the output of panic, potato and rape was not sensitive in most regions;and the output of millet was generally not sensitive.Moreover, some suggestions for the adjustment of agro-industrial structure in Gansu Province were proposed. |
