我国城市过度扩张占用耕地带来粮食安全问题的现状要求城市建设节约用地、紧凑发展,而在传统城市建设模式下,紧凑建设带来的城市人口高度集中又引发了交通拥堵、环境恶化、能源紧张等诸多城市社会问题,两者之间的矛盾促使我们寻找新的城市建设模式。本文对长沙市三角洲地区规划实践中所提出的紧凑型城市建设模式进行简要分析,总结这一建设模式的关键要素,并对以此模式为蓝本进行建设的三角洲地区以及湘江世纪城实施后效果进行分析评价,为此模式的进一步优化研究提供依据。 The current situation of over-expansion of urban areas that occupies arable land to bring about food security requires that urban construction saves land and develops compactly. However, under the traditional urban construction mode, the urban population brought by compact construction is highly concentrated, causing traffic congestion, environmental deterioration and energy shortage And many other urban social issues, the contradiction between the two prompted us to find a new mode of urban construction. This article briefly analyzes the compact urban construction mode proposed in the planning practice of the Delta in Changsha City, summarizes the key elements of this construction mode, and carries out the effect after the implementation of the Delta and Xiang River Century City based on this model Analysis and evaluation, to provide a basis for further optimization of this model.
