Spatial And Temporal Characteristics Of Carbon Emissions In Jiangxi Province

Climate change is the biggest global concern today. Many studies show that the climate change is caused by human activities. The driving factor of global warming is greenhouse gases, particularly the carbon dioxide whose accounted for the entire 76% of greenhouse gas emissions. The Chinese government set up a strategic goal of building a conservation-minded and environmentally friendly society guided by the scientific approach. Jiangxi Province have began to carry out low-carbon development pilot project in 2010. Consequently, grasp the macro characteristics of a region's carbon emissions, and then take measures to reduce the number of carbon emissions with a purpose are significance of this magnificent.This thesis taking the research on carbon emissions spatial and temporal characteristics of provincial as its mainstream, systematically calculated the number of carbon emissions and probes into the status of the carbon emissions, then research on two typical cases put forward the need for a low carbon economy in Jiangxi, in order to provide a reference for similar areas.Firstly, based on collecting a mass data and arranging the internal and external greenhouse gas emissions research, especially carbon emissions research, this thesis summarizes the various carbon emissions factors, and also builds the measuring and calculating methods of carbon emissions; Secondly, it using remote sensing, GIS means of land-use land-cover(LULC) change in Jiangxi province and calculate the carbon emissions caused by LULC change; Thirdly, it calculated the carbon emissions caused by cement production and human respiration; Fourthly, based on calculation of carbon emissions caused by energy utilization, it analysis the overall carbon dioxide emissions condition and trend of spatial and temporal characteristics of eleven prefecture-level cities. Fifthly, it analysis and predict the carbon emissions of two counties which one is industrial type and the other is ecotype.The results are listed as follows: The province's carbon dioxide emissions is on the rise, from 86.59 million tons in 1995 to 165.71 million tons in 2009; Paddy fields turn into settlements led to the largest carbon emissions, the second is forest land turn into settlements. We should prudent to expend cities; Energy consumption is the main source of carbon emissions, we should increase the energy efficiency; Carbon emissions caused by energy concentrated in the north and northwest of Jiangxi, Pingxiang, Xinyu, Yichun, Jiujiang accounted for 60-70% of whole of the energy carbon emissions; The analysis of Guixi and Zixi counties show that: low-carbon economy is the only way to dealing with the contradictions of economic development and environmental.
