Large amounts of investment on oil and gas industry have important effect onthe infrastructure which includes cities and communications, and this will become an importantfactor of changing the urban structure of Xinjiang. In the 1950s, Kelamayi and Dushanzi cities haveappeared by the petroleum exploration in the west of the Juggar Basin, which not only changedthe single role of Xinjiang oasis agricultural city but also made the distribution of cites broken fromnatural oasis for the first time, and the network trend of urban spatial structures emerged.
