摘要
Abstract
Against the background of food security, starting with the trend and changes of total grain output, grain sowing area and grain yield per unit area, and according to the grain production data of Henan province since 1978, a total analysis was made on the comprehensive capacity of grain production in Henan province with the quantitative method. The results show that: after a period of slow and fluctuant growth, the total grain yield made a rapid growth after 2004; while, after a relatively substantial fluctuant from 1978 to 2002, grain sowing area made a unidirectional increase since 2003, and then the proportion reached record highs in the whole country; grain yield per unit area with the exception of a few years reduction, it has basically increased, especially since 2004 there appears a trend of acceleration.关键词
