Study on the Dynamic System of Neo-Magnetic Composed with Newtown from the Practice of Xi'an

摘要

This paper focuses on the methodology and dynamic system of New-town practice, which corresponds with the policy-oriented principle in Xi'an, and analyzes the relativity between the evolution of spatial structure and the influential factors such as the land usage, resources endowment, economic development, population growth, by studying the process of Xi'an Newtown construction over the past 20 years. Xi'an Newtown is attached to the main city area like a magnetic container, absorbing population either from urban or rural area. Furthermore, it is more like a huge magnetic field composed with multiple small poles. To some extent, New-town practice in Xi'an follows the policy-oriented principle, and meanwhile meets the goal of regeneration of cultural heritages, ecological restoration and low-carbon control. Yet it is very different from the experiences of building an anti-magnetic system of metropolitans in European countries after the World War II. Till now, seven relatively independent "edge cities" have came into being with new cluster centers and edge-economic growth poles, which effectively keeps the suburbs from spreading disorderly.
