Description

Technical Field

[0001] The present invention relates to the technical field of low-carbon development evaluation, and in particular to a system and method for evaluating the level of urban low-carbon development based on carbon fixation and emission reduction. Background Art

[0002] According to statistics from the Global Carbon Project, about 37×109t of CO2 is emitted into the atmosphere every year, of which urban areas account for about 75% of the total. Therefore, urban ecosystems have become the main battlefield for carbon sequestration and emission reduction. CO2 emitted from urban areas mainly comes from the accelerating urbanization process. The design, construction and operation of urban infrastructure have destroyed the spatial pattern of the original urban ecosystem, and human activities have reduced the resilience of urban ecosystems to climate change. The urban ecosystem is a complex system of interaction between artificial construction and natural ecosystems in cities. Human activities have greatly affected the carbon sequestration and emission reduction capacity of urban ecosystems. In addition, strengthening carbon sequestration and emission reduction in urban ecosystems will help improve the health level and sustainable development capacity of urban ecosystems, thereby improving the quality of life and health level of urban residents.

[0003] In summary, urban development and construction have a significant impact on carbon sequestration and emission reduction in urban ecosystems. However, current research on urban ecosystems mainly focuses on their accessibility, fairness, health effects and climate regulation capabilities. There is a lack of research focusing on the carbon sequestration and emission reduction efficiency of urban ecosystems. In addition, most related studies focus on the carbon sink efficiency of blue-green spaces in urban ecosystems.
