【摘要】:為了實現(xiàn)資源的效用最大化、提供福建省糧食安全新的數(shù)據(jù)支持,分析了2003—2012年福建省糧食消費的特點,預測未來年份的糧食需求量。結果表明:第一,福建省糧食消費總量呈現(xiàn)遞增的趨勢,糧食消費結構也有較大幅度調(diào)整;第二,人均糧食消費量增加了44 kg,人均口糧消費量減少了12 kg,人均飼料糧消費量增加了55 kg,飼料用糧大幅增加,是導致福建省人均糧食消費量大幅增長的主要原因;第三,比較不同經(jīng)濟發(fā)展水平下和平衡膳食模式下的人均糧食需求量,發(fā)現(xiàn)差異明顯,實際人均消費量遠高于合理人均需求量,不合理的食物消費結構造成了不合理的糧食浪費現(xiàn)象;第四,按照高、中、低3種不同的人均糧食需求量分別預測全省的糧食需求量,基于平衡膳食模式的糧食需求量能較真實地反映福建省的實際需求量,即2020、2025年全省糧食需求量分別為1222萬t、1243萬t。
[Abstract]:In order to maximize the utility of resources and provide new data support for food security in Fujian Province, the characteristics of grain consumption in Fujian Province from 2003 to 2012 were analyzed and the grain demand in future years was predicted. The results show that: first, the total grain consumption in Fujian Province shows an increasing trend, and the structure of grain consumption is also adjusted by a large margin; Second, the per capita grain consumption increased by 44 kg, the per capita ration consumption decreased by 12 kg, the per capita feed consumption increased significantly by 55 kg, which was the main reason for the increase of the per capita grain consumption in Fujian Province. Third, comparing the food demand per capita under different levels of economic development and the balanced diet model, we find that the difference is obvious, and the actual per capita consumption is far higher than the reasonable per capita demand. Unreasonable food consumption structure caused unreasonable food waste; Fourthly, according to the high, medium and low per capita grain demand, the grain demand of the whole province is predicted separately, and the grain demand based on the balanced diet model can more truly reflect the actual demand in Fujian Province. In other words, the grain demand of the province was 12.22 million t and 12.43 million t respectively in 2020,2025.
