The results showed that: 1the level variatio of the urba trasportatio developmet is sigificat durig 1985 to The cities which located beside atioal road ad alog the railway i North Xijiag are relatively developmet i high level ad the reciprocal cites are cocetrated i south Xijiag but disperse.2the cocetratio ratio substatial fluctuated durig this period, the cities of Urumqi, Karamay,Chagji, Aksu has impacted freight trasport sigificatly, regio oequilibrium coefficiet is lower ad i the obviously tred of depletio, the chage i value is ot large about odes, which have bee impacted by the developed degree of oasis cities ad the physiographic coditios.3the cities of Urumqi, Keramy, Chagji ad Shihezi have sigificatly impacted other cities i Xijiag i differet years. 4The ceter regio of traffic trasportatio is reiforcemet gradual evolvig space structure of tow based o traffic agle. The chage of the secodary ode city is obvious, the role of Keramay city is gradual fade i the trasportatio system i Xijiag, but Shihezi city is promiece i role of orth Tiasha Moutais ecoomy belt. Durig the evolve i 20 years, Urumqi city has become the cities ceter, Shihezi city is the secodary ceter, Kashigar ad Miqua cities are the third ceter, Karamay, Yiig, Wusu ad Kuerle cities are importat odes cities system.
