气候变化对农作物生产的影响与应对策略

Impact of Climate Change on Crop Production and Its Coping Strategy

气候变化是国际社会公认的最主要的全球性环境问题之一,也是当今科学研究关注的焦点。气候变化影响粮食与所有农作物生产,研究影响的形成与应对策略是关系到我国国民经济发展、社会稳定的全局性重大战略问题。采用实地考察、经验总结、文献调研的方法研究气候变化对我国主要作物生产的影响及应对策略,获得有价值的结果和结论:气候变暖将影响我国粮食安全和主要农作物生产,有利有弊。但相对于利,弊有更强的不确定性。为了适应气候变化,应对气候变化,必须从策略、理念、方法、技术等方面形成相应的体系,从农业顶层设计,在作物领域建立应对气候变化的科学体系、技术体系以及生产体系。

Climate change is recognized as one of the major global environmental problems by the interna-tional community, and it is also the attention focus of the scientific research. Climate change has great influence to each aspect of natural and human social, at the same time affect the food and all crop production, and it is related to the national economic development and social stability of the global important strategy problem. The impact and coping strategies results of climate change on crop production studied by field survey, experience and paper collection showed that: the climate change had both advantageous and disadvantageous on food security and main crops production. The disadvantageous were more unstable. In order to adapt to and cope with climate change, re-searchers must form the integrated system which built up with strategies, theory, methods, tech-niques etc., and must design programs from the top-level of agriculture to establish scientific sys-tem, technology system and production system for crop production.
