Abstract: The world is going through a climate change mainly characterized by warming up. “Greenhouse effect”, “global warming”, etc. domains have become hot topics for scholars, but the studies about impact of climate change on temperate fruit trees is very few, and the relevant research information is lack of integration and sorting. This paper outlined the trend of global climate change, and summarized the effects of climate change on phenological period, chilling capacity, ecological adaptability, fruit yield and quality of temperate fruit trees. In response to these problems, the paper proposed to stduy the law of climate change and mechanism of plant physiological responses; put forward comprehensive cultivation measures; and advocated the cultivation of new varieties with less requiretment to low-temperature and good resistance to insect pests and diseases, so as to adapt to warm temperature in the future.

Key words: climate change, temperate fruit tree, CO2, phenology, insect pests and diseases
