中国食品生产消费过程中农用化学品足迹分析

Agrochemicals footprints analysis on food producing and consumption in China

食品生产农用化学品足迹占我国农用化学品施用总量的比重长期高达90%以上,有限的农地面积和巨大的食品需求压力是我国农用化学品长期过量使用的根本动因;1990—2005年间,除水果以外,粮食、蔬菜、油料、肉蛋奶等食品单位质量农用化学品足迹都持续增大;农村人口由于粮食消费总量较大,人均年食品消费农用化学品足迹长期高于城镇人口;整合环境库兹涅茨曲线理论分析得出,增加农民经济收入、改善其食品消费结构将有效的减轻我国农地食品生产压力,进而遏制农用化学品施用量持续增加的态势。

The agrochemicals footprints of food production in that of total agriculture always keep a percentage of more than 90%. It is the increasing food consumption demand under the condition of vast population and limited farmland that accelerates the use of agrochemicals. The agrochemicals footprints per unit mass of food keep increasing except for fruits during the year 1990 to 2005, and the agrochemicals footprints of per capita food consumption yearly of rural people keep higher than that of urban people which have less grain consumed in total, that is contrary to academic deduce. Integrating the research data with EKC found that the food consumption level of rural people is close connected with total agroehemicals footprints of China. So it is the fundamental method to increase the income of people and improve the food consumption level of rural people for reducing the use of chemical fertilizers and pesticides in China.
