【 摘 要 】

The consensus of using the compact city as a model for urban sustainable development has inevitably led to governments restricting outer urban expansion as an urban management tool. Urban growth boundaries (UGBs) have become one of the most widely used policy tools to achieve this goal. To evaluate the impact of UGBs on urban sustainable development in Melbourne, Australia, we compare the temporal and spatial changes of population, dwelling density, and growth before and after the implementation of the UGB policy in the Melbourne metropolitan area. The results indicate that, since the implementation of the UGB policy, the urban population, dwelling density, and growth have significantly accelerated; however, nearly half of the new population is located on the urban fringe. Based on the pressure of population growth, the UGB in Melbourne has been adjusted frequently, which has reduced its binding force on urban growth. Herein, we focus on the reasons for amendments to the Melbourne UGB, namely, urban density and the intensity of urban land use and compare the UGB policies of the Melbourne and Portland, Oregon (USA), metropolitan areas. We argue that the state government should restrict urban growth boundaries and increase urban density. At the same time, UGB policy must be coordinated with broader government policy, such as urban land use, urban transportation, and environmental planning, and a mechanism should be established to release land supply in defined areas. In addition, governments should expand public participation in the UGB amendment process and in supporting the implementation of the UGB policy.
