Analysis on Changes of Residents'Nutrition Intake and Grain Crop Planting Structure
摘要
Abstract
[Objective]There is a mismatch between food production and demand in China.It is of great significance to study the changes and relationship between residents'nutrition intake and grain crop planting structure for the adjustment of crop planting structure and the security of food supply.[Method]The food consumption data is converted into the nutrient intake data by using the food nutrient composition table to reveal the change rule of the residents'nutrient intake and the crop production structure,and reveal the matching problem between the residents'macro nutrient intake and the crop planting structure.[Result]From 1981 to 2019,the proportion of grain,rice and wheat planting area showed significant changes in the same direction with the daily protein and carbohydrate intake per capita,while it showed significant changes in the opposite direction with the daily fat intake per capita.The proportion of corn planting area showed an obvious opposite change to the intake of protein and carbohydrate,but kept a high consistency with the intake of fat over time.The proportion of legumes planting area and protein intake showed the same direction of change,the proportion of legumes and potatoes planting area and fat intake showed the same direction of change first and then reverse change,and maintained the same change trend with carbohydrate intake over time.[Conclusion]A nutrition oriented food supply guarantee mechanism should be established to promote the connection between food consumption and crop production.关键词
