Urban sustainable development assessment method based on carbon balance index

Abstract

An urban sustainable development assessment method based on the carbon balance index can measure the influence on the ecological environment caused by the urban development from the perspective of carbon balance and includes the steps: a. building an urban carbon budget calculation model and an urban carbon balance index mode; b. calculating the urban carbon source and carbon sequestration of the long-term sequence, deducting the dynamic variation process of the urban carbon balance index and assessing the urban ecological civilization from the perspective of carbon metabolism; and c. analyzing the main factors which influences the urban carbon balance index and providing a scientific basis for the policy formulation of a low-carbon city. The urban sustainable development assessment method based on the carbon balance index builds the urban balance model and the inquiry method of the driving factors, tries to enable the influence on the ecological system caused by the human to be indexing during the urban development from the perspective of carbon emission through the building of the carbon balance index model, facilitates the scientific understanding of the urban carbon source, the carbon sequestration and the driving factors, and provides scientific support for the urban carbon emission reduction.

Description

technical field [0001] The method belongs to the interdisciplinary technical field of climate change science, urban ecology and geographic information technology. Background technique [0002] At present, my country is in the process of rapid urbanization. How different types of cities can achieve their own "low-carbon survival" is a research topic worthy of attention. Controlling greenhouse gas emissions is an important task to actively respond to global climate change, and it is also an inevitable requirement for cities to achieve low-carbon development, accelerate the transformation of economic development mode, and promote industrial transformation and upgrading. Since 2010, the National Development and Reform Commission has launched low-carbon provinces and low-carbon city pilots and the preparation of provincial-level greenhouse gas emission inventories, and in May 2011 released the "Guidelines for the Preparation of Provincial-level Greenhouse Gas Emission Inventories...

Problems solved by technology

However, due to the limitations of the research focus, these two methods do not reflect the role of carbon sinks in their respective methods, ignoring the impact of human transformation of the natural environment on the entire ecosystem during urban construction, and it is difficult to effectively evaluate the degree of urban sustainable development.
