| Since the reform and opening up,the social and economic development of rural areas in China has achieved remarkable results.The production and living conditions of rural residents have undergone tremendous changes.The impact of human activities on the natural environment and human environment of the rural areas and surrounding areas has become more profound.Among the many rural ecological problems,the continuous growth of carbon emissions is one of them.The rapid growth of rural carbon emissions has greatly hindered the speed of national ecological civilization construction and delayed the realization of the energy conservation and emission reduction strategic goals.The western part of Inner Mongolia Autonomous Region is an important ecological barrier zone.Its ecological environment is very fragile and sensitive to temperature.The continuous increase of carbon emissions causes the temperature rise to have a huge impact on the climate and cause irreversible consequences.Therefore,research on rural carbon emissions and its influencing factors,and designing emission reduction paths for carbon emissions in rural areas on the basis of this,is necessary to respond to the needs of the country's rural revitalization strategy,promote green and livable rural construction,and achieve energy conservation and emission reduction tasks.At present,research on carbon emissions is mostly limited to national,urban and regional scales,and there is a lack of research on micro-scale rural scale carbon emissions.Under the background of global carbon emission reduction and building beautiful China,study the carbon emissions of rural regional systems,analyze the composition and characteristics of rural carbon emissions,reveal the factors affecting rural carbon emissions and carbon emission efficiency,and explore the carbon of different rural sectors in rural areas.Emission response,deepening small-scale carbon emission research,and formulating energy-saving and emission-reduction policies in line with actual science and rationality have important theoretical and practical significance.This study mainly addresses the following key issues:(1)What are the differences and similarities between the carbon emissions of rural areas that are dominated by agricultural production and industrial production,and how they are quantitatively expressed and characterized;(2)Rural systems What is the correlation between carbon emissions and different factors in various internal departments,and the extent to which different factors affect carbon emissions;(3)What is the relationship between rural residents'attributes and carbon emissions of various sectors;(4)When carbon emissions What is the carbon emission efficiency of the rural system when outputting variables,how to reduce the input of each input factor for carbon emission efficiency,so as to achieve the purpose of reducing carbon emissionsThis study selects Yijinhuoluo,which is led by energy production,and Hangjinhou,which is dominated by agricultural production,as a case study,builds a rural carbon emission accounting list,uses field research data,and uses SPSS and DEAP2.1 technologies to adopt carbon emission factors.Coefficient method,correlation analysis method,stepwise regression method and DEA(data envelopment analysis method),explore the characteristics of rural carbon emissions,reveal rural carbon emission influencing factors and carbon emission efficiency,and design carbon emission reduction paths in rural areas.The main conclusions are as follows:(1)Analysis of rural system carbon emissions shows that the total amount o f carbon emissions in rural areas is greater than that of Hangjinhou,with the tot al amount being 7041.548t and 447.61114t respectively,and the carbon emissions per household are 31.58t and 23.94t.Sorting sources of carbon emissions by se ctor:Yijinhuoluo fossil energy consumption>Clean energy>Iivestock>biomass>agric ultural production>family life;Hangjinhouqi carbon emission sources ranked as fo ssil energy>livestock and poultry>clean energy>agriculture Production>Biomass En ergy>Family Life.There are similarities and differences in the carbon sources of the two flags.(2)Analysis of factors affecting carbon emissions,the factors affecting rural carbon emissions are complex.The factors affecting rural carbon emissions in Yijinhuoluo and Hangjinhou have the same characteristics and large differences.Through analysis,the paper finds that the correlation between the carbon emissions generated by each factor and the total carbon emissions of the sector is:the correlation coefficient of coal consumption carbon emissions in the energy consumption of Yijinhuoluo is 0.804,the minimum is 0.550 gasoline,and liquefied petroleum Gas and fuelwood are not related.Among the factors of agriculture and animal husbandry,the correlation coefficient of chemical fertilizer is 0.734,and the smallest is 0.604 for pig breeding.The irrelevant is the use of agricultural film,aquaculture and poultry farming.Among the family life factors,the correlation coefficient of liquor is 0.784,and the smallest is 0.442.The unrelated factors are plastic bag use,disposable chopsticks,smoking,beer consumption,daily travel and waste disposal.Among the family attribute factors,the highest correlation coefficient with carbon emission is age-0.522,and the smallest is family income 0.420;the correlation coefficient of carbon consumption of power consumption in Hangjinhou energy consumption is 0.724,the minimum is gasoline 0.508,liquefied petroleum gas and fuelwood are not Related.Among the factors of agriculture and animal husbandry,the correlation coefficient of sheep breeding is 0.720,the smallest is 0.603,and the irrelevant is cattle,donkey,pig and poultry farming,agricultural film use and pesticide use.The correlation coefficient of food in the family life factor is 0.910,and the smallest is 0.600 for meat consumption.The irrelevant factors include the use of plastic bags,the use of disposable chopsticks,the number of cigarettes,the consumption of liquor and beer,and daily travel.Among the family attribute factors,the highest correlation coefficient with carbon emissions is age-0.566,and the smallest is 0.309 for family housing.(3)The construction of carbon emission regression model,through the multivariate stepwise regression model analysis,quantifies the relationship between different production and living factors and carbon emissions.The optimal regression equation for the three sectors of Yijinhuoluo is,energy carbon emission = 0.541 X Coal +0.559 X diesel+0.379 X electricity+0.163 X gasoline+0.024 X fuelwood;carbon emissions of agriculture and animal husbandry=0.680X cow+0.584 X sheep+0.138 X fertilizer+0.045 X pig+0.005 X film +0.004 X pod+0.003 x pesticides;living carbon emissions = 0.499 x grain + 0.464 x liquor + 0.267 x meat volume + 0.089 x beer + 0.067 x clothing purchase +0.031 x electric car travel +0.024 × garbage +0.015 x disposable chopsticks+0.014 x washing powder.The optimal regression equation for the three departments of Hangjinhouqi is:energy carbon emission = 0.516 x diesel + 0.349 x coal + 0.318 x gasoline + 0.083 x electricity;carbon emissions of agriculture and animal husbandry =0.645 x sheep+ 0.586 x fertilizer+ 0.214 X cattle + 0.084 X mulch + 0.054 X pig+ 0.030 X donkey + 0.015 X pesticide + 0.008 X poultry + 0.010 X irrigated area;household carbon emissions = 0.624 X family population + 0.226 X family monthly income-0.158 X cultural level.(4)The analysis of carbon emission efficiency and the comprehensive analysis of carbon emission efficiency show that the rural carbon emission efficiency of Hangjinhou is better than that of Yijinhuoluo.In the evaluation of carbon emission efficiency by sector,the energy carbon emission efficiency of Hangjinhou is better than that of Yijinhuoluo;the average efficiency,pure technical efficiency,and scale efficiency of energy consumption carbon emission efficiency of Yijinhuoluo are 0.992,0.995,and 0.997,respectively.The maximum input fuelwood is 399.035,followed by gasoline 105.030,coal at least 0.259,and the three efficiencies of Hangjinhou are 1 to achieve DEA effective,less redundant;agricultural carbon emission efficiency is the same as the two countys,three efficiency The average value is 1.The input redundancy is in some villages,but the redundancy is small,and the carbon emission efficiency is high.The Yijinhuoluo of animal husbandry is subject to technical efficiency constraints,which is lower than Hangjinhou and Hangjinhou.The efficiency is higher than the Yijinhuoluo 0.2,the pure technical efficiency is higher than 0.286,the scale efficiency is lower than the Yijinhuoluo 0.095,and the importing redundancy of the two flags is large,which requires a lot of adjustment;the household living carbon The emission efficiency has a higher flag.The Hangjinhou flag is slightly better.The average efficiency,pure technical efficiency,and scale efficiency of the second flag are 0.993,0.997,0.996,and 0.996,0.999,and 0.998,respectively.The most influential factor is the meat consumption of Yijinhuoluo,which is 1.888.The smallest is the food consumption of Hangjinhou.It can be seen that the living consumption and daily eating habits of the two flags are quite different.(5)Based on the above research results,the rural area carbon emission reduction path for the Yijinhuoluo of the Energy County and the Hangjinhou of the Agricultural County was proposed.First of all,Yijinhuoluo should control the utilization of high-carbon energy,eliminate high-carbon energy sources,build biogas energy production facilities based on the advantages of animal husbandry,and increase the utilization rate and penetration rate of clean energy.Second,appropriately reduce the input factors of agriculture,optimize the input ratio,and scientifically plant.Third,aiming at the structure and types of animal husbandry,we will establish a linkage mechanism to ensure the harmless treatment of manure,upgrade the level of science and technology,and optimize the breeding mode.Finally,advocate residents to develop good habits,promote low-carbon environmental protection,avoid unnecessary carbon emissions,regularly organize residents'learning and the advantages of low-carbon life,and create a virtuous cycle of rural carbon emissions.Hangjinhou should first accelerate the transformation of existing energy utilization structure,consolidate the proportion of clean energy such as electricity in daily life,enhance the influence of clean energy such as electricity on reducing carbon emissions,promote scientific and technological upgrading,improve energy use environment,and improve energy.usage efficiency.Second,agricultural carbon emissions need to quantitatively control input factors,eliminate empirical operations,change the scientific and technological level of existing agricultural input factors,create a virtuous cycle of low input and high output,break existing planting systems,optimize planting patterns,and intensively Control carbon emissions output.Thirdly,the breeding house will be upgraded to minimize the management and cleaning energy consumption level of the pens,and the treatment of feed low-carbonization technology will be carried out to improve the efficiency of feed utilization and reduce carbon emissions.Finally,it is necessary to improve the awareness of energy conservation and emission reduction while ensuring survivable consumption,efficiently use various living resources,reduce waste,and reduce carbon emissions of individuals and households as much as possible. |
