Abstract：In recent years， various programs for the protection， inheritance and utilization of the Grand Canal culture， as well as numerous canal museums， have listed only six provinces and two municipalities when they refer to the canals of Sui and Tang Dynasties， namely Zhejiang， Jiangsu， Anhui， Shandong， Henan， Hebei， Tianjin and Beijing. Other than a couple of commonsense errors， the capitals and surrounding environs of the two dynasties have been surprisingly overlooked in these programs. As a matter of fact， the networked waterways serving different functions built during the Sui and Tang dynasties were spread across various regions. In addition to parading， transportation， irrigation， and residential water use， the canals in the capital city regions were needed to maintain the supply and stability of the capital cities. Rivers and canals in the vast arid and semi-arid areas of Northwest China mainly served for farming， people's everyday life use and military purposes. The Yangtze and Huai River canals essentially supplied food， silk cloth， urban protection， and fire prevention for the two capitals and other cities. The Northeast and South China canals were mostly involved in military operations. Canals in Tibet chiefly served agricultural irrigation.
