A Study On The Temporal Characteristics And Influential Factors Of Land-Use Carbon Emission In Yuanjiang

Land use is an important entry point for the study of low-carbon economy and carbon emissions.Firstly,this paper summarizes the domestic and foreign land use carbon emissions related research,from the factors of land use,carbon emissions accounting aspects of carbon emission effects of land use,to sort out the relevant research contents involved,determine the direction of further research based on the related research.Secondly,the factors of carbon emissions in the base period and T period differences expressed as multiplication and addition mode,using the LMDI decomposition method to calculate carbon emissions contribution value and contribution rate of each factor,and analyze the effects of various factors on carbon emissions during the whole study period.Through the above analysis,this paper draws the following conclusions:(1)Over the years of construction land carbon emissions and net carbon emissions are over the same trend,they also reached the maximum value in 2011 during the study period,the construction determines the trend of net carbon emissions with the trends of carbon emissions in Yuanjiang.(2)Land use intensity per unit of GDP and carbon emissions per unit of land are the contributing factors of carbon emission reduction,the intensity of unit GDP land use is great for carbon emission reduction,and the intensity of carbon emissions per unit land is relatively small.However,it fluctuated greatly during the whole study period.(3)Rural land use one-way structure change is an important reason for the growth of carbon emissions in Yuanjiang.Reducing carbon emission intensity can effectively reduce urban carbon emissions.In the short term,the effect of carbon emission reduction can be achieved by reducing the amount of fossil energy consumption,but it is not conducive to the economic development of Yuanjiang in the long run.Reducing the intensity of land use per unit of GDP has significant effect on urban carbon emission reduction.But in the study period,the contribution rate of land use intensity per unit of GDP is a smooth line,and the decrease of unit GDP land use intensity depends on technological innovation and industrial upgrading.This paper takes Yuanjiang as the research object,based on the analysis ofcarbon emission data of various land use types in the past ten years.And find out the factors that affect the carbon emissions,and quantitatively study the influence of various factors on carbon emissions.To providing scientific policy recommendations based on data.It has important practical significance for the sustainable utilization completed the "13th Five-Year" low carbon development goals and implementation of the Yuanjiang municipal land and low carbon utilization.
