Embodiment Construction

[0042] The present invention will be described in detail below.

[0043] A method for determining the carbon sink capacity of sphagnum swamp wetlands, comprising:

[0044] Measure the emission flux of greenhouse gases from sphagnum swamp wetlands B;

[0045] Measure the carbon sink C1 of herbaceous plants and the carbon sink C2 of sphagnum moss in the sphagnum swamp wetland;

[0046] Measure the decomposition rate D of sphagnum swamp wetlands;

[0047] The carbon sink X of the peat moss swamp wetland is calculated, and the calculation formula is: X=C1+C2-B-D.

[0048] The method for determining the carbon sink capacity of sphagnum swamp wetlands in the present application can capture the main points of carbon sequestration and carbon emission, and more objectively evaluate the carbon sink capacity of sphagnum swamp wetlands.

[0049] In this embodiment, the steps for measuring the emission flux B of greenhouse gases are as follows:

Abstract

The invention discloses a method for measuring the carbon sequestration capacity of a sphagnum marsh wetland. The method comprises the following steps: measuring the emission flux B of greenhouse gas of the sphagnum marsh wetland; measuring the carbon sink C1 of the herbaceous plants of the sphagnum marsh wetland and the carbon sink C2 of the sphagnum plants; measuring the decomposition rate D of the sphagnum marsh wetland; and calculating to obtain the carbon sink X of the sphagnum marsh wetland, wherein the calculation formula is X = C1 + C2-B-D. According to the method for determining the carbon sequestration capacity of the sphagnum marsh wetland, main carbon sequestration and carbon emission points can be captured, and the carbon sequestration capacity of the sphagnum marsh wetland can be evaluated more objectively.

Description

technical field [0001] The invention relates to the field of carbon sink determination, in particular to a method for determining the carbon sink capacity of sphagnum swamp wetlands. Background technique [0002] Sphagnum plants belong to the genus Sphagnum, and there are about 50 species of sphagnum plants in China. Sphagnum moss is one of the dominant species of nutrient-poor peatlands, and is the most important plant that accumulates peat in peatlands. Sphagnum moss is a carbon sequestration star in wetland types, because sphagnum mosses decompose slowly after death, and their living bodies and residues accumulate in wetlands, creating considerable biomass for peatlands, and its carbon sink function protrude. Carbon sink refers to the contribution of wetland ecosystems to CO in the atmosphere. 2 It plays a role in net absorption. Different from carbon storage, carbon sink is the newly added carbon in wetlands every year, which is a concept of carbon increment. [0003...
