摘要
系统总结了甘肃省科技攻关重大项目"甘肃干旱生态环境对全球气候变暖的响应研究"等3个课题的主要成果和研究进展。在揭示甘肃省现代气候变化基本特征是冬暖夏干的基础上,比较系统地综述了越冬作物(冬小麦、冬油菜)、喜凉作物(春小麦、马铃薯、胡麻)和喜温作物(玉米、棉花、酿酒葡萄)等8种主要农作物的生长发育、适生种植区高度和种植面积、产量和品质等对现代气候变化的响应特征。现代气候变化对甘肃农作物生长的影响非常突出,已对农作物安全生产与农业可持续发展构成了严重威胁。其研究结果为建立现代农业发展模式,旱作农业生产机制,农作物安全生产提供科学的指导意见。
This paper summarizes the major achievements and progresses in three research projects including the Gansu province＇s Key Project ＂Study of the impact of climate warming on the arid ecological environment in Gansu＂. The study revealed the characteristics of modem climate changes, which is warming in winters and dry in summers. The characteristics of the impact of climate change on overwinter crops （winter wheat, rapeseed）, cool temperature-philic crops （ spring wheat, potato, flax） and tropical crops （ corn, cotton, wine grape） in growth and development, planting area and suitable planting altitude, and yield and quality were analyzed systematically. It showed that the crop planting was seriously influenced by modern climate change and the safe crop production and sustainable development were threatened in Gansu province. The results will provide scientific guidance for the establishment of modem agricultural models, arid agricultural production mechanism and the safety of crop production in this region.
