以黄土高原地区多年平均粮食增长率为依据,1.6%和1.0%两种人口年增长速度、和300kg、350kg、400kg三种人均年占有粮食水平组成的四个方案,对全区及其12个分区的粮食产需进行了预测。结果表明,2000年全区粮食产需仍达不到平衡状态,其中以人口年增长率为1.6%,人均年占粮水平为400kg的方案,全区到2028年才能达到产需平衡;各分区达到平衡的时间差异很大,个别分区因人口增长过快使缺粮更趋严重。最后,作者提出通过加强水利、农田基本建设、推广良种和增加肥料投入等措施,促进粮食增长。
Based on the multi-year average grain growth rate in the Loess Plateau, the annual growth rates of 1.6% and 1.0% of the population, and the three programs of annual grain occupancy of 300kg, 350kg and 400kg, Regional food production needs to be predicted. The results show that in 2000 the region’s grain production and demand still can not reach the equilibrium state, of which the annual population growth rate of 1.6% per capita annual grain level of 400kg program, the region can not achieve the balance of production and demand until 2028; the district The timing of reaching a very different point varies greatly. Individual zoning is exacerbated by the rapid population growth. Finally, the author proposes to promote food growth through measures such as strengthening water conservancy, farmland capital construction, promoting good varieties and increasing fertilizer inputs.
