Example Embodiment

[0012] Specific implementation mode 1: This embodiment is a method for improving the carbon sequestration capacity of marshlands through the following steps:

[0013] 1. Implementation of civil works in the target area for improving the carbon sequestration capacity of marshlands: divide the target area for implementing the improvement of carbon sequestration capacity of marshlands into several units, each with an area of ​​100~200hm 2 , Excavate a closed annular trench at the periphery of each unit. The depth of the closed annular trench is 1.2~1.5m and the width is 5~10m. The "cross"-shaped open water ditch is excavated inside each unit, and the water is clear. The width of the ditch is 1.5-2.0m, and the depth is 1.0-1.2m. The open water ditch is connected to the closed annular ditch, and the river or diversion canal communicates with the closed annular ditch at the peripheral boundary of each unit for water supply and drainage; Collect soil and vegetation dug out of closed ring...

Example Embodiment

[0017] Embodiment 2: The difference between this embodiment and the first embodiment is that the target area in step 1 is an inland river floodplain type natural herbaceous swamp; the target area has river replenishment or diversion canal water supply and drainage, and the water supply and drainage volume can be adjusted. The other steps and parameters are the same as in the first embodiment.

Example Embodiment

[0018] Specific embodiment three: This embodiment is different from specific embodiments one or two in that the water quality of the marshland in the target area in step one must meet the "GB11607-89 Fishery Water Quality Standard" and "NY5051-2001 Non-polluted Food Freshwater Aquaculture Water Quality "Requirements. The other steps and parameters are the same as in the first or second embodiment.

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 ...
