Ecological protection red line delimiting method for carbon sequestration function of terrestrial ecosystem

Abstract

The invention discloses an ecological protection red line delimiting method for a carbon sequestration function of a terrestrial ecosystem, and the method comprises the steps: selecting a typical terrestrial ecosystem as an evaluation object in a land area range of a research area; collecting data of the evaluation object related to the carbon sequestration function; constructing a land ecosystem carbon sequestration function importance evaluation index from three dimensions of carbon reserve, carbon sink and carbon sequestration potential, determining an index grading assignment standard, and dividing the evaluation index into a plurality of grades; evaluating the importance of carbon reserves, carbon sequestration and carbon sequestration potential of the terrestrial ecosystem, and respectively extracting pattern spots with the highest importance levels of the three; performing spatial superposition and combination to generate extremely important pattern spots with a comprehensive carbon sequestration function; and carrying out aggregation and converting into a vector range of the ecological protection red line. According to the method, the problem that the protection red line of the carbon sequestration function of the terrestrial ecosystem cannot be accurately delimited can be solved, and scientific and technological support is provided for expanding ecological protection red line delimitation, positively coping with global climate changes and achieving a carbon neutralization target.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method for delineating ecological protection red lines for the carbon fixation function of terrestrial ecosystems. Background technique [0002] Currently, terrestrial ecosystems absorb CO from the atmosphere through photosynthesis of vegetation 2 , is recognized by the international community today as the most economically feasible and environmentally friendly way to mitigate atmospheric CO 2 One of the important ways to increase the concentration. How to increase the carbon storage and carbon sequestration capacity of terrestrial ecosystems is the focus of widespread attention of the international community. my country has a vast territory, significant regional differences, and various types of ecosystems. There are obvious differences in the spatial distribution of carbon sources and carbon sinks in terrestrial ecosystems. Scientifically delineate the protec...
