【摘要】：当前我国进入新常态发展阶段,新的经济社会形势要求提升城市发展质量,实现有序建设、适度开发、高效运行,需要对快速城镇化时期增长拉动型城市规划带来的负面效应进行反思。城市增长边界源于美国,是抑制城市蔓延的政策工具之一,目前已被引入我国总体规划编制体系。然而不同编制主体对于增长边界内涵的理解不同,划定方法也多依据经验定性判断,难以发挥实效。本文以长三角次中心城市之一的苏州为例,结合格网划定,综合考虑生态、建设条件、人口分布、经济发展、基础设施等方面因素,运用主成分分析法进行增长潜力分析,并结合聚类分析确定城市增长区,划定城市弹性增长边界,对于转型发展期的其他城市有借鉴意义。
[Abstract]:At present, our country has entered a new normal stage of development, and the new economic and social situation requires that the quality of urban development be improved, orderly construction is achieved, moderately developed, and efficiently operated. It is necessary to reflect on the negative effects brought by the growth-pull urban planning in the period of rapid urbanization. The boundary of urban growth originated from the United States and is one of the policy tools to curb the urban sprawl. It has been introduced into the overall planning system of our country at present. However, different compilers have different understanding of the connotation of growth boundary, and the methods of delineation are often based on empirical qualitative judgment, so it is difficult to give full play to the actual effect. Taking Suzhou, one of the sub-central cities in the Yangtze River Delta, as an example, combined with grid delineation, considering the factors of ecology, construction conditions, population distribution, economic development, infrastructure and so on, this paper uses principal component analysis to analyze the growth potential. Combined with cluster analysis to determine urban growth area and delineate the boundary of urban elastic growth, it has reference significance for other cities in the period of transition and development.
