Abstract

Abstract

Cities are the main source of global greenhouse gas emissions. Due to the complexity of urban ecosystems and the uncertainty of human activities, there are significant differences in carbon cycling characteristics among different cities. Currently, carbon flux monitoring methods mainly include "bottom-up" and "top-down" approaches. However, there are few reports on the review of their analytical framework and monitoring methods. This paper provides a systematic review of urban carbon cycle influencing factors, carbon flux observation, and simulation methods, and introduces typical urban carbon monitoring networks both domestically and internationally. It also points out future research directions, including developing high-resolution global carbon assimilation theories and technologies, verifying and promoting the distribution characteristics of carbon sources/sinks in different urban land surfaces, tracing the anthropogenic carbon emissions and ecosystem carbon source/sink patterns in urban regions, and carrying out research on the exchange mechanisms between complex urban land surfaces and the atmosphere, as well as the environmental response mechanisms of urban carbon flux. This study will increase our understanding of the global carbon cycle and provide scientific support for China to implement the dual-carbon strategy, address climate negotiations and carbon inventory, and evaluate carbon neutrality.
