In this paper,the climate related corn yield in 55 stations in Gansu province is resolved by means of EOF and REOF. According to the analysis of loading vecter, southeast Gansu is of most representative in corn yield. Furthermore,the climate related corn yield areas can be divided into 5 natural climatic zones:Eastern Gansu, Southern Gansu,Middle and Humid Mountain Area,Arid Mountain Area and Western Irrigated Agricultural Areas of Gansu.The first main component of the climate related corn yield can represent the temporal tendency of the climate related corn yield of Gansu.It is well correlated to the OLR in May and September of the same year.
