Ecological Compensation Standards Measurement And Time-Space Evolution In Changzhutan Area Of Hunan Province

Carbon footprint is a method for assessing the impact of regional carbon emissions,using the difference between carbon emissions and carbon absorption to determine the inter-regional ecological compensation standards.The article uses the carbon footprint theory and method to estimate the carbon emissions,carbon absorption and carbon deficit/surplus from 2007 to 2018 in the Changzhutan area.On this basis,factors such as population and area are added,and the concept of carbon deficit sensitivity is cited.,Further calculate the ecological compensation standard,and demonstrate the temporal and spatial evolution and law of the ecological compensation standard during 12 years.The results of the study show that:During the 12 years,the carbon emissions in Changzhutan area showed an overall increase and then a downward trend,and the overall carbon absorption showed a steadily increasing trend;Zhuzhou and Xiangtan were the absolute compensating subjects.The ecological compensation amount is paid,and Changsha can get an ecological compensation amount of 170,000 yuan in 2018.Among them,the ecological compensation amount that Xiangtan needs to pay is much higher than that of Changsha and Zhuzhou.In 12 years,Xiangtan needs to pay an average of 86.94 million yuan.Changsha averages It needs to pay 10.97 million yuan,Zhuzhou needs to pay an average of 9.89 million yuan.The research results and methods can provide reference and reference for the formulation and implementation of ecological environmental protection and ecological compensation policies in Hunan Province and Changzhutan area,as well as for interregional ecological compensation research and practice in other regions.The main conclusions are as follows:(1)The carbon footprint of the Changzhutan area showed an "M"-shaped change from 2007 to 2018,which was the maximum point in 2013 and also an inflection point.The decline trend has been obvious since 2013(2)The carbon carrying capacity has basically stabilized during a 12-year period with little fluctuation.(3)The change trend of carbon deficit in Changzhutan area is similar to carbon footprint,which is greatly affected by carbon footprint.(4)The carbon deficit sensitivity of Changsha is generally lower than that of Zhuzhou and Xiangtan during 12 years,indicating that Xiangtan is greatly affected by carbon emissions and is a city with more carbon emissions;Zhuzhou ’s carbon deficit sensitivity is slightly greater than that of Changsha,indicating that Zhuzhou is affected by The impact of carbon emissions is greater than that of Changsha;Changsha is least affected by carbon emissions in these three cities.(5)Judging from the proposed compensation standards,Zhuzhou and Xiangtan are absolute compensation entities.Each year,the compensation recipient should pay the corresponding ecological compensation amount,and Changsha was successfully transformed from the compensation subject into the compensation recipient in 201 8 The previous 11 years The ecological compensation amount needs to be paid to the ecological compensation recipient area every year,but in 2018,170,000 ecological compensation amount can be obtained.In 12 years,the ecological compensation amount that Xiangtan needs to pay is much higher than that in Changsha and Zhuzhou In 12 years,Xiangtan needs to pay an average of 86.94 million yuan,Changsha needs to pay an average of 10.97 million yuan,and Zhuzhou needs to pay an average of 9.89 million yuan.(6)In 12 years,Xiangtan,as the main body of ecological compensation,accounted for the largest proportion of ecological compensation to be paid in Changzhutan area,and Changsha accounted for a slightly higher proportion than Zhuzhou.
