Study on Measurement and Zoning of Ecological Compensation Value in Pearl River-West River Economic Belt Based on Improved Three-Dimensional Ecological Footprint Modeling
The difficulty in the construction of the ecological compensation mechanism lies in clarifying the subject and object of compensation,evaluating the priority sequence of compensation and accurately calculating the compensation standard.The construction of a scientific and effective ecological compensation mechanism is conducive to the rational distribution of ecological protection responsibilities in the upstream and downstream of the basin.Taking the prefecture-level cities in the Pearl River-West River Economic Belt as the research unit,this paper combines the improved three-dimensional ecological footprint model with the estimation of ecosystem service value to measure the value and standard of ecological compensation in each city from 2005 to 2020,and introduces the priority of ecological compensation,and finally delineates five types of sub-districts:priority payment,potential payment,balance,potential compensation and priority compensation.The results showed that:1)In 2020,the ecological compensation deficit in the economic belt was 28.809 billion yuan,the highest payment value in Guangzhou was 18.514 billion yuan,and the per capita ecological compensation standard was 987.92 yuan,and only Chongzuo received ecological compensation,with a compensation value of 68 million yuan and a per capita compensation standard of 32.62 yuan.2)Guangzhou,Foshan and Nanning had long been priority payment areas;Chongzuo had long been a priority compensation area;Zhaoqing,Liuzhou and Baise had been transformed into potential payment areas in recent years;Laibin,Guigang,Wuzhou and Yunfu were balanced areas;The priority compensation area and potential compensation area of the economic belt had gradually changed to the priority payment area,potential payment area and balance area.3)Guangzhou,Foshan and Nanning should take the lead in paying ecological compensation to balance the inter-regional ecological protection responsibilities of the economic belt,and coordinate the inter-regional ecological protection and co-governance relationship;Priority should be given to Chongzuo ecological compensation to benefit from ecological protection and obtain economic support for ecological and environmental governance.
