Study on influencing factors and carbon sink value of green space in Taiyuan
Under the goal of"carbon peaking and carbon neutrality",low-carbon sinks have become an important issue of concern to countries,regions,enterprises,and even individuals.It is significant for urban sustainable development planning and improving carbon sink efficiency to determine the influencing factors and carbon sink value of urban green space from the urban scale.The findings showed that:l)Normalized vegetation index(NDVI)had the highest spatial explanatory power for net ecosystem productivity(NEP)(q values between 0.68 and 0.81),the second is the interaction of land use(LULC)∩ elevation(DEM),DEM ∩(temperature)T,DEM ∩precipitation(R)and DEM ∩ solar radiation(SSD),the force can reach 40％.2)The potential carbon sink value generated by green space in Taiyuan is irregular in spatial distribution.3)For 2021,the estimated value of the carbon sink of Taiyuan's green space is as follows:Afforestation cost method(102.078 4 million yuan)＞market value method(16.765 3 million yuan).It can be seen that the carbon sink value estimated by the market value method is low.How the carbon sink value of urban green space can be included in the carbon trading market needs to be further explored.
