Abstract：Thestudy focusesonthewhole-lifecarbonemissionsandlong-term carbon sink benefitsof ecologicalslopeprotectiontechnologiesinthewater-levelfluctuationzone，systematicallcomparingtheenvironmentalpefomanceoffourtecniques： geosyntheticthedimensionalmats，cologicalbags，vegetatedconceteandplantingconcrete.Quantifymaterialcarboneisios based on SimaPro 9.O software （Geotechnical three-dimensional mesh 2.140 0kgC02-eq/kg 、ecological bag 0.0202kgC02eq/kg 、vegetation concrete 0.1760kgC02-eq/kg. 、plant concrete 0.1810kgC02-en/kg） ，combined with carbon emission accounting during transportation， construction and operation stages，it was found that geotechnical materials（Geo-three-dimensional mesh 5.842kgCO2-eq/m2 、Ecological bag 5.050kgCO2-eq/m2 ）Due to the low material consumption， the carbon emission per unit area is only 16% of that of ecological concrete （Vegetation concrete 32.032kgCO2-eq/m2 、Plant concrete 32.598kgC02-eq ），which has significant short-term emission reductionadvantages.Furthersimulatingthe3O-yearoperationofecologicalslopeprotectiontechnologyforgrassplanting，itsplant carbon absorption （108kgCO2-eq/m2） can cover the entire life cycle carbon emissions of the material，achieving a net carbon benefit of more than 67kgCO2-eq/m2
