Abstract: Delimitation of urban growth boundary can guide the orderly development of urban space and effectively control the unordered urban sprawl. Taking the typical resource city Guixi as the research object, this paper explores effective urban growth boundary delimitation methods from the aspects of spatial suitability evaluation, population carrying capacity, city scale and two-plan (urban master planning and land-use planning) integration connection. The spatial suitability evaluation takes the natural, spatial accessibility and ecological conditions into consideration and determines the ecological baseline for area not suitable for development and suitability levels for area suitable for development area through the cluster analysis. The baseline and the suitability levels are used to determine the development direction of urban growth boundary. The population of 2020 is forecasted through model of GM(1,1), and the maximum local population is verified based on land resources and water resources. Meanwhile, the urban size is predicated and the sphere of urban growth boundary is delimited. The construction land is reduced by means of spatial suitability evaluation, population carrying capacity, city scale prediction and two-plan integration connection, and thus, the rigid boundary and elastic boundary can be delimited.

Key words: model of GM(1,1), population carrying capacity, spatial suitability evaluation, two-plan integration connection, urban growth boundary
