摘要
我国居民膳食习惯从关注数量充足向更强调膳食均衡搭配转向,改变了乡村主体行为策略和空间作用行为。基于大食物观理念,在认知居民膳食需求导向下乡村主体空间行为基础上,从食物供给、食物均衡、食物健康3个维度构建乡村价值指标体系,分析重庆市乡村价值的空间特征及优势价值类型,进而解析其实现机制。结果表明:(1)大食物观理念下因乡村主体空间作用行为的差异,乡村价值分为食物供给价值、食物均衡价值和食物健康价值;(2)重庆市乡村价值总体上呈现出“东高西低、局部突出”的空间格局,其中主城都市区以食物供给价值为主导、渝东南武陵山区城镇群以食物健康价值为主导、渝东北三峡库区城镇群以食物均衡价值为主导;(3)从资源禀赋、农业活动、农业政策3个维度解读了乡村价值的实现机制,据此提出大食物观理念下乡村多元价值实现的建议。
Nowadays,the dietary habits of Chinese residents have changed from paying attention to sufficient quantity to emphasis on the balanced collocation of meals,which leads to the changed behavioral strategy and behavior of rural subjects.Based on the concept of big food and on the basis of the cognition of the spatial behavior of rural subjects under the guidance of residents’dietary needs,the rural value index system was constructed from three dimensions of food supply,food balance and food health,and the spatial characteristics and advantageous value types of rural value in Chongqing were analyzed,and the realization mechanism was also analyzed.The results showed that:(1)The rural value could be divided into food supply value,food balance value and food health value due to the difference of the spatial action behavior of rural subjects under the concept of big food;(2)The rural value of Chongqing presented a spatial pattern of“high in the east,low in the west and prominent in some areas”.The main urban area was dominated by the food supply value,the Wuling Mountain area in southeast Chongqing was dominated by the food health value,and the Three Gorges Reservoir area was dominated by the food balance value.(3)The realization mechanism of rural value was interpreted from the three dimensions of resource endowment,agricultural activity and agricultural policy,based on which the authors put forward suggestions on the realization of rural multi-value under the concept of big food.
