| 摘 要： | 利用青海高原上两个不同海拔高度区农业气象观测站1980-2007年的观测资料,就低海拔地(民和)和高海拔地(诺木洪)的气候变化及其对春小麦生长发育和产量的影响差异进行研究.结果显示:28年来民和和诺木洪两站均存在变暖趋势,且高海拔地区的线性增暖幅度大于低海拔地区.春小麦对气候变暖的响应表现在低海拔地区播种期提前,成熟期...

| Abstract: | Impact of climate warming on the growth and yields of spring wheat at high and low altitudes in the Qinghai Plateau was studied by using the observation data obtained at Minhe and Nuomuhong agricultural meteorological stations from 1980 to 2007.The results show that during the past 28 years the air temperature had an increase trend both at high and low altitudes,and the warming amplitude of annual air temperature was larger at high altitude than at low altitude.Responses of spring wheat at low altitude were... |
