[Research progress on quantitative evaluation methods of urban ecological carrying capacity]

Area of Science:

• Environmental Science
• Urban Planning
• Sustainability Science

Background:

• Quantitative evaluation of urban ecological carrying capacity (UECC) is essential for assessing sustainable urban development.
• Understanding UECC components and characteristics is crucial for enriching its conceptual framework.

Purpose of the Study:

• To systematically review and categorize existing methods for quantifying UECC.
• To analyze the advantages and disadvantages of various quantitative evaluation techniques.
• To predict future trends in UECC assessment and suggest areas for further research.

Main Methods:

• Categorization of static evaluation methods: ecological footprint, comprehensive evaluation, state space, net primary productivity, and carbon-oxygen balance.
• Categorization of dynamic simulation prediction methods: system dynamics models, BP neural network models, and grey prediction models.
• Comparative analysis of the strengths and weaknesses of identified quantitative methods.

Main Results:

• A comprehensive overview of static and dynamic methods for quantifying UECC.
• Identification of the pros and cons associated with each evaluation approach.
• Insights into the current landscape of UECC assessment methodologies.

Conclusions:

• Further research is needed to strengthen theoretical foundations and construct robust indicator systems for UECC.
• Establishing clear evaluation principles and optimizing quantitative methods are vital for accurate UECC assessment.
• This review provides a foundation for advancing the field of urban ecological carrying capacity evaluation.
