Abstract: Climaterelated challenges for agricultural ecosystems and regional food safety have become a major concern due to projected global warming characterized by the increase of annual global average land surface temperature. The impacts of climate warming on agricultural development and ecosystems have become a focused issue for society. Studies on the impact and mechanism of climate warming on crop growing periods, morphological characteristics, physiology, yield formation and quality are the scientific basis for identifying the impact of climate warming on agriculture and making policies against climate warming. Based on the basic characteristic of climate warming in Northwest China, we summarized the research advances in the impacts of climatic warming on the growth, physiology, ecology, yield and quality of main food crops, economic crops and special fruit trees, farmland ecological environment, agricultural meteorological disasters, plant diseases and insect pests, and discussed the deficiency in current researches. This review makes a further prospect for the key points in future research on the impact of climate warming on agriculture and agricultural ecology in Northwest China: (1) Sufficiently use simulating, testing, and observing measures to disclose the impacts of multi-factors of climate change on major crops; (2) Study the impacts of climate warming on the physiology and ecology of major crops; (3) Study the responses of agricultural meteorological disasters to climate warming and take risk evaluations on agricultural meteorological disasters and find out countermeasures; (4) Study technological strategy in the refined dynamic agricultural planting regional division, agricultural structural distribution and planting system to cope with the climate warming.
