全球气候变化对温带果树的影响

全球正经历一次以变暖为主要特征的气候变化。“温室效应”、“全球变暖”等领域成为学者们研究的热点，但气候变化对温带果树所带来的影响研究甚少，相关研究信息缺乏整合与梳理。概述了全球气候的变化趋势，综述了气候变化对温带果树的物候期、需冷量、生态适应性、果实的产量、质量等影响。针对出现的问题，建议研究气候变化规律以及植物生理反应的作用机制，并提出了综合的栽培措施和提倡培育对低温需求小、抗病虫的新果树品种来适应未来温暖的气候。

Impact of Global Climate Change on Temperate Fruit Tree

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.
