On Urban Land Development Boundary Oriented by the New Type Urbanization Policy: A Case of Yiwu City

The paper summarizes the traditional method to delimit the urban land development boundary which aims to make a good balance of urban sprawl and ecology protection in a "industrial" model, while under the new type urbanization policy, a "urbanization" mode seems to be more appropriate with China's development. In the paper, on the basis of traditional methods to delimit urban land development boundary under the background of the new urbanization policy, we try to explore a delimitation method which is more closer to the "urbanization" mode. We take the downtown of Yiwu for an example and obtain results of the urban land development boundary of Yiwu in the year of 2020 in both of the two modes, one of them is in the "industrial" model and guided with the "sector theory", and the other is in the "urbanization" mode and guided with the "multiple nuclei theory", and then we compare the thoughts and the results. The paper chooses the second method, namely the method which is under the new urbanization background and is close to the "urbanization" mode as the better. At last, we propose the requirements and methods to apply the method, following with some recommendations and opinions.
