摘要
全球气候呈现变暖的趋势,对农业生产和粮食安全产生重大影响,并成为当今全球环境变化关注的热点问题之一。本文采用文献综述与比较研究的方法,系统分析了气候变化对光资源、温度、土壤质量和水环境等农业生产要素的影响机理,探讨了气候变化对我国作物种植区域和种植制度、农作物病虫害、农业生产能力以及农业经济与管理等方面的实际影响,通过梳理国外应对气候变化的主要农业战略,提出新时期我国应对气候变化的农业可持续发展策略。
A number of studies indicate increasing global climate warming especially in recent decades. Climate warming greatly influences global agro-production and food security — the focus of global environmental change. This paper proposes a structural and orientational framework for scientifically addressing climatic change impact on agro-production. Through literature review and comparative studies, the paper systematically summarizes influencing mechanisms and effect of climate warming on such agro-production factors as light, temperature, soil quality and water environment. The impact of climate warming on cultivation regions, cropping systems, crop pests, agro-production capacity, agro-economy and farm management is analyzed. Then, suitable climate-adapted agro-development strategies are put forward for different regions in China. The strategies are carefully selected from a repository of international tested climatic change countermeasures in agriculture at national or district level.
