【摘要】：当今,我国城市发展已经进入高速发展阶段,主要表现城市规模的扩张,即:人口规模的快速膨胀和用地规模的无序扩张。城市规模扩张给城市的发展带来了正向的、负向的影响。一方面城市扩张可以推动城市经济发展,提升城市竞争力;另一方面城市扩张带来了一系列“城市的宜居性问题”,主要表现为:土地紧张交通拥堵、环境污染、生态质量下降等,这些问题都促使这城市发展的转型,宜居城市建设则成为首选。在合理的城市规模下,推进宜居城市建设,既能保证城市经济持续快速增长,也能满足城市居民日益增长的城市环境高质量要求,是21世纪我国城镇化建设面临的重大课题。本文在总结分析时代背景、综述国内外研究现状、梳理宜居城市建设和城市边界管控之间关系的基础上,重点研究如下内容:一是从客观层面对我国26个省会城市宜居度及城市规模发展情况进行评价。宜居度方面,根据宜居城市评判标准主要选取四大类(经济、社会、环境、生态)21个指标,对26个省会城市的宜居度进行客观评价,按照地理区位将26省会城市分为三类,分析东部、中部以及西部省会城市宜居水平的时空差异;城市规模方面,主要从城市人口规模和城市用地规模两个方面进行分析。二是建立数学模型分析,提出研究假设,分析城市规模与城市宜居度的关系,最终得出在加入经济、社会、环境、生态等中间变量之后,城市规模与城市宜居度之间的倒U型关系会逐渐显现;在Alonso模型基础上进行扩展,得出城市宜居水平与城市规模的二次函数,求得宜居水平下的最优城市规模。三是通过实证分析,得出建设宜居城市的具体对策:要加强城市边界的管控,防止城市规模过度扩张;其次主张城市坚持以公共交通为导向的城市发展模式(TOD,Transit-Oriented Development),明确坚持TOD发展模式是实现宜居城市发展的关键空间型路径。
[Abstract]:Nowadays, the urban development of our country has entered the stage of rapid development, which mainly shows the expansion of urban scale, that is, the rapid expansion of population scale and the disorderly expansion of land use scale. The expansion of urban scale has brought positive and negative influence to the development of city. On the one hand, urban expansion can promote urban economic development and enhance urban competitiveness; on the other hand, urban expansion has brought a series of "urban livable problems", which are mainly manifested in: tight land traffic congestion, environmental pollution, ecological quality decline and so on. These problems promote the transformation of urban development, and livable city construction has become the first choice. Under the reasonable urban scale, promoting the construction of livable cities can not only ensure the sustained and rapid growth of urban economy, but also meet the growing requirements of urban environment and high quality of urban environment, which is an important task facing China's urbanization construction in the 21st century. On the basis of summing up and analyzing the background of the times, summarizing the research status at home and abroad, and combing the relationship between livable city construction and urban boundary control, this paper focuses on the following contents: first, the livable degree and urban scale development of 26 provincial capitals in China are evaluated from the objective level. In the aspect of livable degree, according to the evaluation standard of livable city, 21 indexes of four categories (economy, society, environment, ecology) are selected to evaluate the livable degree of 26 provincial capital cities objectively. According to the geographical location, the 26 provincial capital cities are divided into three categories, and the temporal and spatial differences of livable level in the eastern, central and western provincial capitals are analyzed. In the aspect of urban scale, it is mainly analyzed from two aspects: the scale of urban population and the scale of urban land use. The second is to establish mathematical model analysis, put forward the research hypothesis, analyze the relationship between urban scale and urban livable degree, and finally conclude that the inverted U-shaped relationship between urban size and urban livable degree will gradually appear after adding economic, social, environmental, ecological and other intermediate variables. On the basis of Alonso model, the quadratic function of urban livable level and urban scale is obtained, and the optimal urban scale under livable level is obtained. Third, through empirical analysis, the concrete countermeasures for building livable cities are obtained: we should strengthen the control of urban boundaries and prevent the excessive expansion of urban scale; secondly, we advocate that cities adhere to the urban development model guided by public transport (TOD,Transit-Oriented Development), clearly insists that TOD development model is the key spatial path to achieve livable city development.
