摘　　要：果蔬作为中国膳食营养结构中不可或缺的重要组成部分,其产业在中国农业经济中占据着重要的位置。以人为本是中国改革发展的立国之本,从人体营养健康的角度研究中国果蔬产业未来的发展趋势就显得势在必行。该研究基于营养学视角,通过构建营养指标体系,运用系统聚类法筛选出可以代表不同营养类型的典型性果蔬,同时运用遗传算法解决在满足中国居民不同年龄组每日膳食营养正常摄入条件下如何购买典型性果蔬,即成本最小化的最优线性规划问题。结果表明:对于不同年龄组,在既定正常营养成分摄入的前提下,中国居民每日蔬菜购买量高于水果购买量,且叶菜类和根菜类的购买量远远高于其它典型性果蔬。未来中国果蔬产业的发展需要进一步完善产业布局,大力发展不同营养类型的果蔬。并且进一步整合果蔬加工型产业,保证食品卫生安全,扶持龙头型企业,打造"绿色果蔬"品牌。As the indispensable important component of Chinese dietary nutrition structure,fruits and vegetables occupy a very important position in Chinese agricultural economy.People-oriented is the founding of Chinese reform development.Researching on the trend of the development of Chinese fruit and vegetable industry from the perspective of human nutrition health is imperative.Based on the perspective of nutrition,by building the nutrition index system and using the method of system clustering,different types of typical fruits and vegetables were screened.At the same time it could solve the problem about Chinese residents which meet different age groups under the condition of normal daily dietary nutrition intake how to buy typicality fruits and vegetables by using genetic algorithm,namely the optimal linear programming problem of minimizing the cost.The results showed that for different age groups,under the premise of normal nutritional intake,Chinese residents daily purchased more vegetables than fruit.Purchase of leafy and root vegetables was much higher than other typical fruits and vegetables.The future development of Chinese fruit and vegetable industry needed to further perfect the industrial layout,vigorously developing the different industrial types of fruits and vegetables nutrition.And integrating the fruit and vegetable processing industry to ensure the safety of food hygiene,supporting the leading enterprises and creating‘green fruit and vegetable＇brand were necessary.
