A carbon balance-based method for optimizing the scale of regional "three-environment" land use

Abstract

The invention relates to an 'ecological-living-industrial' land scale optimization method based on carbon balance. The method comprises the following steps: (1) calculating the regional net carbon emission based on the regional carbon yield and carbon emission; (2) with zero emission as the goal, constructing an objective equation of regional 'ecological-living-industrial' land scale optimization; (3) constructing a constraint equation of regional 'ecological-living-industrial' land scale optimization; (4) further calculating the regional net carbon emission according to the calculation result of the constructed constraint equation; and (5) if the regional net carbon emission is less than or equal to zero, judging that the regional 'ecological-living-industrial' land scale is reasonable; and if the regional net carbon emission is greater than 0, returning to step (3), and further optimizing the 'ecological-living-industrial' land scale until zero emission is achieved. Through the method, the regional 'ecological-living-industrial' land scale can be easily optimized. The method is of great significance to the study of regional ecological balance. The result of 'ecological-living-industrial' land scale optimization can guide land use planning in the future, and is advantageous to the sustainable development of the society.

Description

technical field [0001] The invention relates to a carbon balance-based method for optimizing the scale of regional "three life" land use, which is suitable for the research of regional ecology and belongs to the field of resource environment and ecology. Background technique [0002] Under the influence of human activities, the scale of "three life" land (production land, living land and ecological land) has changed significantly, which directly leads to changes in the regional carbon cycle process. In order to maintain the balance of the regional ecosystem, it is necessary to optimize the scale of the regional "three life" land use. As the main link between human beings and ecosystems, the carbon cycle process can be used as an important reference index for optimizing the scale of "three life" land use. It is of great significance to study the scale optimization of regional "three life" land use based on carbon balance to maintain ecological security. [0003] The current...

Problems solved by technology

Among the above methods, the evaluation index selected by the former is relatively single, and the interaction mechanism between land use and carbon balance cannot be fully considered; the latter considers the mechanism of carbon cycle better, but due to the need to calculate the balance of carbon and oxygen at the same time, the calculation The process is more complicated, more data are required, and it is difficult to apply in data-deficient areas
