Abstract: Based on the data of daily mean temperature and wheat growth and development period from 1980 to 2007 in three weather stations of Qaidam Basin,which were Golmud,Delingha and Nuomuhong weather stations,it analyzed the impacts of climate change on wheat growth in irrigation district of Qaidam basin.The results indicated that: 1) the first day when the average daily temperature above 0℃ and 10 ℃ steadily shifted earlier and the last day became later from 1980 to 2007 and the wheat growing period became longer.2) In the three weather stations,sowing date of wheat was postponed,while harvest date got earlier,wheat obtained a shorting growing and development time.3) As there were much heat resources in Nuomuhong,some vegetables with shorter growing time could be planted after wheat harvested.
