中文摘要	应用甘肃省武威荒漠生态与农业气象试验站19812019年灌溉春小麦观测资料,采用线性回归分析、相关分析、Cubic函数等方法,分析了近39年气候变化对灌溉春小麦生长的影响。结果表明:19512019年该地区气候变化呈现暖湿化趋势,气温、降水量变化的线性倾向率分别为0.326℃·10a~( -1)、5.694 mm·10a~(-1);灌溉春小麦对气候变化的响应表现在春季发育期每10 a延后0~ 1 d,夏季发育期每10 a提前1~ 2 d,生育期每10 a缩短2~ 3 d,产量每10 a增加500~ 550 kg·hm~(-2)·10a~(-1);相关分析显示,气温对灌溉春小麦生长的影响程度高于降水量、日照时数和≥0℃活动积温;在灌溉春小麦整个生长发育过程中,其阶段生长和产量对气候变化的响应不完全一致,气候变化使该地区播种~三叶期的营养生长阶段延长,拔节~成熟期的生殖生长阶段缩短,全生长期缩短;拔节~抽穗期气温增加对灌溉春小麦产量增加有极显著的正效应(相关系数R= 0.431),播种~成熟期气温增加对灌溉春小麦产量增加有显著的正效应(相关系数R= 0.354) 。气候暖湿化使河西走廊地区热量资源丰富,提高了作物增产潜力,但也使得病虫害加剧,防控难度加大。该地区灌溉春小麦生长变化是作物响应气候变化和农业生产适应气候变化的共同结果。
英文摘要	In this paper,the observation data of irrigated spring wheat from Desert Ecology and Agrometeorological Experimental Station in Wuwei of Gansu Province from 1981 to 2019 were used,and the effect of climate change on spring wheat growth in irrigated agricultural area of Hexi Corridor was preliminarily discussed to provide scientific basis for the agricultural planting structure,variety adjustment,saving water and improving the capacity of coping with climate change and prevention and reduction disaster under the background of climate warming.Linear regression analysis,correlation analysis,and cubic function were used to reveal the influence of climate change on the growth of irrigated spring wheat in recent 39 years.The results showed that the climate change in the region displayed a warm and humid trend from 1951 to 2019,the temperature changed at a rate of 0.326 ℃·10a~(-1),the precipitation changed at a rate of 5.694 ℃·10a~(-1).The response of irrigated spring wheat to climate change was as follows:the growth stage of spring was delayed by 0~1 d·10a~(-1),the growth stage of summer was advanced by 1~2 d·10a~(-1),the growth stage was shortened by 2~3 d·10a~(-1),and the yield was increased by 500~550 kg·hm~(-2)· 10a~(-1).The correlation analysis revealed that the impact of temperature on irrigated spring wheat was higher than precipitation did,the sunlight length and active accumulated temperature greater than or equal to 0℃.In the whole growth stage of irrigated spring wheat,the response of growth stage and yield to climate change were not completely consistent.That is to say it prolonged the nutrition growth stage from sowing to three leaf stage,shortened the reproductive growth stage from jointing to maturing,and resulted in the shortening of the whole growth period.The increase of temperature at jointing to earring stage had a highly positive effect on the yield of irrigated spring wheat(correlation coefficient R = 0.431).The increase of temperature at sowing to maturing stage had a significant positive effect on the yield of irrigated spring wheat (correlation coefficient R = 0.354).Climate warming and humidification increase thermal resources and improve the crop yield potential in Hexi Corridor,but also aggravate disease and pest and increase the difficulty of prevention and control.The growth changes of irrigated spring wheat are the common results of crop response to climate change and agricultural production adapting to climate change in this area.
