历史时期中国酸食空间分布及成因研究

A Historical Study of the Spatial Distribution and Genesis of Chinese Acid-rich Foods

从汉晋南北朝到唐宋时期,中国形成了中原和荆楚两个食酸地区。元明清时期,酸食区域被更广泛地认知,山陕、东北、东南沿海三个酸食重区彰显出来,酸食的空间差异辨识度明显。20世纪的饮食文献资料统计表明,中国酸食分区的历史承传特征明显,酸食空间分布的形成主要与水土酸碱度、资源分布,以及饮食结构、饮食味道味型差异等因素相关。

From the Han,Jin,Southern and Northern Dynasties to the Tang and Song Dynasties,the Central Plains and the Jing-Chu region of China gradually became the two major regions preferring acid-rich foods.During the Yuan and Ming Dynasties,Shaanxi-Shanxi,northeast China and the coastal area of southeast China became the three areas especially preferring acid-rich foods with their respective spatial features.The statistical data in the dietary literature of the 20th century have showed that the geographical distribution of such foods has a clear historical inheritance while the key factors are related to the acidity and alkalinity of the special soil and water,the distribution of resources,the differences in the dietary structure and dietary preferences.
