| 摘 要： | 对甘肃省５５个站点的玉米气候产量经ＥＯＦ及ＲＥＯＦ分解后，通过对其载荷量的分析，表明陇东南地区是甘肃省玉米产量最具代表性的区域，并进一步将甘肃省玉米气候产量划分为５个自然气候区：陇东区、陇南区、中部及阴湿山区、干旱山区、河西灌溉农业区。玉米气候产量的第一主分量可代表甘肃省玉米气候产量的时间趋势。它与同年５～９月份ＯＬＲ有很好的相关关系。

| Abstract: | 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. |
