Modeling method for carbon sequestration accounting of ecological system of mulberry field

Abstract

The invention discloses a modeling method for mulberry field ecosystem carbon sequestration accounting, which comprises the following steps: calculating the total biomass of mulberry twigs for fuel wood combustion by using basic planting information and mulberry felling quantity data of a mulberry field so as to establish a carbon sequestration accounting model for the mulberry felling twigs for fuel wood combustion, which considers carbon offset and greenhouse gas emission during combustion; a carbon release model of mulberry leaf in-situ compost is established to solve the carbon residue of compost, and a carbon sequestration accounting model of cut mulberry leaves is obtained; establishing a carbon sequestration amount model of the silk fibers and the silkworm chrysalis within a 100-year evaluation period; establishing an accounting model for the carbon sequestration amount in the silkworm excrement and the residual food leaves in consideration of compost greenhouse gas emission and carbon dioxide emission by silkworm respiration; seven carbon circulation path modeling such as a mulberry and underground biomass carbon sequestration amount accounting model is established. According to the method, modeling is carried out on carbon loss and carbon offset of seven circulation paths of photosynthesis carbon, an accurate and reliable mulberry field carbon sequestration accounting model is explored, and the method has important significance on quantitative evaluation of mulberry field carbon sequestration.

Description

technical field [0001] The invention relates to the technical field of environmental assessment, in particular to a modeling method for carbon sequestration accounting in a mulberry orchard ecosystem. Background technique [0002] In recent years, global warming has posed a serious threat to the natural environment and human economic development. Climate warming is mainly due to the large amount of greenhouse gas (GHG) emissions including carbon dioxide, methane, and nitrogen oxides caused by human production activities. Greenhouse gas emissions can be measured by the carbon footprint, which refers to the total amount of greenhouse gas emissions and removals produced at all stages of the product's life cycle, expressed in carbon dioxide equivalents (CO2-eq). The carbon footprint detection of products can provide data reference for enterprises to save energy and reduce emissions for low-carbon production. [0003] The textile industry has always been an industry with high en...
