Yuanfeng jiuyu zhi 元豐九域志 "Treatise of the Nine Regions from the Yuanfeng reign-period (1078-1085)" is an imperial geography from the Northern Song period 北宋 (960-1126). It was compiled on imperial order by Wang Cun 王存 (1023-1101), Zeng Zhao 曾肇 (1047-1107) and Li Dechu 李德芻. The latter has also written a geographical treatise on local administration called Yuanfeng junxian zhi 元豐郡縣志.
The imperial geography comprises 10 juan, including descriptions covering the four capitals (sijing 四京), the 23 provinces (lu 路 "circuits") and administration units beyond imperial territory (huawaizhou 化外州), like the native prefectures (jimizhou 羈縻州) of aboriginal tribes in the southwest. Below the circuit (provincial) level each prefecture is described, the geographical circumstances, household numbers, the main local products, the historical development of the location, and garrisons.
The Yuanfeng jiuyu zhi is the most detailed geographic description of every region of the Song empire. A modern reprint was published by the Zhonghua Book Company 中華書局 in 1984.
