RESEARCH OF EFFECT OF GLOBAL ENVIRONMENT CHANGE ON AGRICULTURAL CROPS

从CO2 浓度升高、CO2 浓度与温度升高以及CO2 浓度与水分变化的协同作用、CO2 浓度升高与环境盐胁迫的协同作用和作物产量预测模拟及其适应对策 4个方面总结了近年来国内外关于农业生产对全球环境变化的响应与适应及其变化趋势的研究进展 ,指出目前人类关于农业生产对未来全球环境变化响应机理的理解与预测很有限 ,提出中国未来需要拟加强的研究领域 .参

Global environment change would directly and indirectly seriously affect agricultural crop production, and threaten the ability of global food supply. New advances in the studies on the responses of agricultural crop production to the global environment change were reviewed in four aspects: increasing CO 2 concentration; interactions between increasing CO 2 concentration and temperature, and between CO 2 concentration increasing and water change; interaction between increasing CO 2 concentration and saline stress, and prediction simulation and adaptation strategy on the responses of crop yield to global environment change. The results suggested that the human abilities for understanding and predicting the responses mechanism of agricultural production to global environment change were very limited at present; especially the future directions related to the responses of agricultural production to global environment change were emphasized in China.
