基于区域尺度的城市承载力评价研究——以上海市为例

Study on Evaluation of Urban Carrying Capacity Based on Regional Scale——Setting Shanghai City as an Example

摘要:

在城市化带来交通拥堵、生态失衡及环境污染等诸多问题的背景下，开展城市承载力研究，对于保证城市的全面、协调、可持续发展具有重要意义。本文将传统的承载力评价研究方法与互联网大数据下的兴趣点和空间路网数据相结合，建立了上海市承载力评价指标体系。运用信息论中的熵方法，对上海市各区域的承载力进行了评价和分析。结果表明，上海市各地区的承载力明显分为5个等级，等级间的差距非常明显。分析了上海市各区域的实际情况，找出了其承载力发展的不足，提出了上海市可持续发展的建议和对策。

Abstract:

Urbanization has caused various problems, such as traffic congestion, ecological imbalance, and environmental pollution. Investigating the urban carrying capacity becomes crucial in order to ensure the development of a city in a comprehensive, coordinated, and sustainable way. Combining traditional method with big data from the internet, including interest points and spatial road network, an evaluating system of carrying capacity in Shanghai city has been established. By using onentropy from the information theory, carrying capacity of all regions in Shanghai city have been evaluated and analyzed. It is showed that these regions are divided into five levels, and differences between each neigh are obvious. According to present condition of each region, the deficiency of capacity development has been pointed out, and suggestions and countermeasures for sustainable development in the future have been put forward.
