The result showed that the spatial distribution of National Important Agricultural Heritages remained in a type of agglomeration as a whole with the clustered form in some local regions. Besides, there was a high gathering degree of distribution on the Three terrain ladders and Three economic regions while an unbalanced spatial distribution of provincial regions.
