【摘要】：总结河南省1980—2013年耕地面积、农作物播种面积、粮食总产、种植结构、农业生产要素投入及生产总值的变化特点,分析土地资源、粮食总产变化趋势及上升空间,就未来河南省粮食安全机制进行探析。结果显示,河南省耕地面积上升及维持与政策扶持有关,继续上升幅度收窄,但耕地质量提高的空间较大。播种面积的波动同耕地面积的波动日益趋同,前者对后者的依赖性渐强。粮食总产增速放缓,稳产能力渐强,粮食产量继续大幅增加的压力较大。生产要素投入整体逐年增加,农业总产值直线上升,但占农林牧渔业总产值的比例直线下降。建议继续完善农业激励政策,稳定现有耕地数量,改造中低产田,提高中高产田的比例及土地利用效率,实现藏粮于地;加快科技创新,继续推进科技服务体系建设及"互联网+"现代农业行动,进一步提高农业科技贡献率,做到藏粮于技。
[Abstract]:This paper summarizes the change characteristics of cultivated land area, crop sown area, total grain yield, planting structure, input of agricultural production factors and GDP in Henan Province from 1980 to 2013, and analyzes the change trend and rising space of land resources and total grain production. This paper probes into the grain security mechanism of Henan Province in the future. The results show that the increase and maintenance of cultivated land area in Henan Province is related to the policy support, and the increasing range continues to narrow, but the space for the improvement of cultivated land quality is larger. The fluctuation of sowing area is more and more similar to that of cultivated land, and the former is more and more dependent on the latter. The growth rate of total grain production has slowed, and the ability to stabilize production has become stronger. The pressure on grain production to continue to increase substantially is greater. The input of production factors increased year by year and the total output value of agriculture, forestry, animal husbandry and fishery decreased linearly, but the proportion of the total output value of agriculture, forestry, animal husbandry and fishery decreased sharply. It is suggested that we should continue to improve the agricultural incentive policy, stabilize the amount of existing cultivated land, transform the middle and low yield fields, increase the proportion of medium and high yield fields and land use efficiency, realize grain storage and land use, and speed up scientific and technological innovation. We will continue to promote the construction of science and technology service system and the "Internet" modern agricultural action to further improve the contribution rate of agricultural science and technology, so as to save grain for technology.
