全球气候变化对农业生态系统的影响及研究对策

全球气候变化在不同时间和空间尺度上对农业生态系统产生深刻的影响,并引起了世界各国科学家、政府的极大关注。本文从CO2浓度和气温升高、UV-B辐射增强等方面综述了全球气候变化对作物、土壤、畜牧业、病虫害以及气候灾害的影响,提出了全球气候变化下未来应加强研究的领域。

Effects of global climate change on agriculture ecosystems and research strategy for the future

Global climate change has been born and would be keeping on pricking up in future.It had profound effects on agriculture ecosystems in different time and space scales,and would directly and indirectly seriously affect agricultural crop production,and threaten the ability of global food supply.So many scientists and governments in the world highly pay attention to it.New advances in the studies on the effects of global climate changes on crops,soils,animals,plant diseases and insect pests,and climatic damage were reviewed in following aspects: elevating carbon dioxide concentration and temperature,and increasing ultraviolet-B radiation.The results suggested that the research production for understanding and predicting the effect mechanism of global climate change on agricultural ecosystems were very limited at present.So the research strategies for the future were put forward in the end.
