Abstract:

It is an effective way to scientifically and rationally delimit the urban growth boundary for controlling the disorderly urban expansion and reducing the inefficient urban land use. It is also one of the important contents of space planning exploration in China. The urban growth boundary demarcation should be based on the regional resources conditions and construction and development level of different regions, and the appropriate indicators and methods should be selected according to the local conditions so as to more accurately reflect the actuality and demand of urban development. The urban development in arid areas is significantly affected by the oasis-desert ecosystem. The contradiction between people and land is more prominent in the process of urban expansion. The delimitation of urban growth boundary must reflect the coordination of resources, environment and economic and social development. In this paper, it was attempted to carry out the delimitation of urban growth boundary in Urumqi so as to explore the feasible methods for delimiting the urban growth boundary in arid regions based on the research ideas of resources environment background and construction and development level. The results showed that:    The combination of restrictive evaluation and suitability evaluation could be used to well delimit the urban growth boundary in arid area; Oasis could be regarded as an evaluation unit of land potential so as to make the delimitation of urban growth boundary in arid area more reasonable and applicable;   Delimitation of urban growth boundary was divided into the permanent boundary and periodic boundary, which could be used to guide the development of urban land.
