Abstract: Urumqi, the large city in Western region of China, belongs to the oasis of arid region, and its eco environ mental issues are increasingly serious. The study on this urban ecological environment will be benefit to recognizethe ecological essence of the confliction between urban development and environmental protection.
Basis on investigation of urban eco environment of Urumqi, its urban eco environmental features weresummed up. Drought elimate of Urumqi results to the short of the water resources, which limits the urban development. Its natural landforms are put to rational use. Its animal and plant resources are diversity. Shelterbeltnet work is perfected.Urban greenbelt is being planned. Six principles of dividing urban ecological function dis-trict were present based on the theory of landscape ecology and urban ecology, including integration approach, regional difference, landscape heterogeneity, function and structure, urban dynamic trends and eco environmental capacity.
3 landscape functional districts were divided, including the urban construction and center district which islocated in city proper and peripheries, the urban eological balance and development district that is located insouthern and northern suburbs, and the urban ecological protection and reserved district which is located inmount ain regions around.
For urban ecological control, suitable suggestion, such as environmental control engineering. biological control engincering, landscape ecological construction and ecological landscape management, were presented.Land-scape ecologial construction is gap bet ween engineering control and management control, in which regional inte-gration and contagion is underlined. For oasis city in arid region, landscape ecological construction is crucial.

Key words: Urumqi eco environment, Ecological functional district, ecology control
