摘  要:
论文对全国耕地面积、耕地复种指数、粮食作物与非粮作物比例关系、粮食作物单产等变化态势进行了系统分析。结果表明,到2020年全国耕地面积有望保住1.2亿hm2红线,但难度很大;粮食作物面积比重过低或过高均不利于粮食安全,全国粮食作物面积比重宜保持在66%~69%,到2020年全国粮食总产量为5.7亿~6.5亿t。

摘  要:
The paper systematically analyzed the change trend of the arable land area,multiple cropping indexes,crop yields per unit area and the proportion between food crops and non-food crops.The results showed that the arable land area by 2020 can be hardly kept in the red line of 120 million ha.The too low or high proportion of the crop area was neither good for food security.The crop area should be maintained at 66% to 69% of the total arable land,and the country's total grain output was 570 ~ 650 million t in 2020.
