specific Embodiment approach 1

[0012] Specific implementation mode 1: In this implementation mode, a method for improving the carbon sequestration capacity of swampland is carried out through the following steps:

[0013] 1. Implementation of civil engineering in the target area for improving the carbon sequestration capacity of the swamp: Divide the target area for improving the carbon sequestration capacity of the swamp into several units, each with an area of ​​100-200hm 2 , Excavate a closed circular ditch around the boundary of each unit. The depth of the closed circular ditch is 1.2-1.5m and the width is 5-10m. The width of the ditch is 1.5-2.0m, and the depth is 1.0-1.2m. The open ditch communicates with the closed circular ditch, and the river or diversion channel communicates with the closed circular ditch at the boundary of each unit for water supply and drainage; among them, Collect the soil and vegetation excavated from the closed circular ditch and the open ditch respectively. The soil is used ...

specific Embodiment approach 2

[0017] Embodiment 2: This embodiment differs from Embodiment 1 in that the target area in step 1 is an inland river floodplain type natural herbaceous swamp; there are rivers in the target area to replenish water or diversion canals for water supply and drainage, and the water supply and drainage can be adjusted. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0018] Specific implementation mode 3: The difference between this implementation mode and specific implementation mode 1 or 2 is that the water quality of the swamp in the target area in step 1 must comply with "GB11607-89 Fishery Water Quality Standard" and "NY5051-2001 Pollution-free Food Freshwater Aquaculture Water Quality" "Requirements. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for improving the carbon sequestration capability of marsh lands and a method for evaluating the sequestration capability of marsh lands. The methods are used for solving the problems that the biological carbon sequestration capability is reduced due to the vegetation degradation of the existing natural marsh lands, the carbon sequestration capability of water bodies of the natural marsh lands is low, and no method is provided for simply and quickly evaluating the carbon sequestration capability of the marsh lands. The method comprises the steps of 1, carrying out a building project for improving the carbon sequestration capability of the marsh land in a target area; 2, releasing and reproducing aquatic economic animals for improving the carbon sequestration capability of the marsh land; and 3, recovering the vegetation for improving the carbon sequestration capability of the marsh land. The method for evaluating comprises the step of evaluating the carbon sequestration capability of the marsh land in the target area according to the total sequestrated carbon of the carbon sequestration organisms in the marsh land in a growing period. The method is applied in the technical field of ecological science.

Description

technical field [0001] The invention relates to a method for improving the carbon sequestration capacity of swampland and an evaluation method thereof. Background technique [0002] With atmospheric carbon dioxide (CO 2 ) concentration and the intensification of global warming, more and more attention has been paid to the reduction of greenhouse gas emissions, and the research on how to use terrestrial ecosystems for carbon sequestration activities has become a global concern. The "Kyoto Protocol" uses the carbon sequestration capacity of terrestrial ecosystems to offset emission reduction obligations, but only considers the carbon sequestration capacity of forest ecosystems. In fact, the carbon sequestration capacity of other types of ecosystems cannot be ignored. Swamps are one of the main types of inland natural wetlands on the earth, and also one of the important terrestrial organic carbon pools. However, many factors, such as natural and man-made, jointly affect the ...
