Problems solved by technology

However, human activities dominated by agricultural drainage and reclamation have caused continuous loss of wetlands and serious degradation of wetlands, and the function of carbon sequestration and sinking has been severely reduced
At present, research on carbon sequestration at home and abroad mainly focuses on the breeding of high carbon sequestration plant varieties and artificial planting of trees and grasslands. There are few reports on the applied technology of Hui

Embodiment 1

[0010] Embodiment 1: A water management method for wetland carbon sequestration and sink increase of the present invention, the steps are as follows:

[0011] Step 1: Determination of wetland type: select meadows or swamps with no water on the surface (meadows are community types dominated by perennial mesophytes, which are formed and developed under moderate water conditions. Swamps are A vegetation type dominated by marsh plants formed under conditions of excess water or humidity);

[0012] Step 2: Determination of wetland environmental factors: ① Determination of soil water content. At the beginning of May at the beginning of the year, soil was taken from 5-15 cm below the surface vegetation for testing. Fresh soil samples under the vegetation were taken in a soil box (aluminum box), and then tested at 80 Dry at about ℃ until constant weight, soil water content = (soil wet weight - soil dry weight) / soil dry weight x 100%, the soil water content requirement is 40% to 70%, ...

Abstract

The invention provides a moisture management method for carbon sequestration and carbon sink increase for wetlands, which includes: firstly, selecting a meadow or marsh with logged water on the surface, determining environmental factors of the wed land, determining water content of soil, taking soil for test 5-15cm below surface vegetation on early May, beginning of the year, loading the fresh soil sample below the vegetation with a soil box, and drying the soil to constant weight at about 80 DEG C, wherein soil water content = soil dry weight-soil dry weight/soil dry weightX100%, and the soil water content is required to be 40%-70%; and secondly, determining types of the wetland soil, determining the types to be meadow soil, Baijiang soil or marsh soil, regulating moisture, selecting a water source from underground water or unpolluted river and lake fresh water, and irrigating by direct water diversion through ditches or pumping underground water with a water pump. By the moisture management method, covered rate of the wetland can be increased evidently, vegetation carbon sequestration can be improved, soil carbon storage can be increased, emission of greenhouse gases is reduced,investment is low, cost is low, and the moisture management method is highly applicable.

Description

(1) Technical field [0001] The invention relates to a wetland carbon fixation and sink increase technology, specifically a water management method for wetland carbon fixation and sink sink increase. (2) Background technology [0002] Since the industrial revolution, due to the intensification of large-scale human activities, such as burning a large amount of fossil fuels, deforestation, and land reclamation for agriculture, the natural process of the ecosystem carbon cycle and the inherent carbon balance of the biosphere have been changed, resulting in atmospheric CO 2 、CH 4 and N 2 The continuous increase in the concentration of greenhouse gases such as O has triggered the problem of global change and seriously threatened the survival and sustainable development of human society. As one of the three major ecosystems on the earth, wetlands are one of the most important carbon pools in terrestrial ecosystems, accounting for 12% to 24% of the total carbon storage in terrestr...
