Abstract:
The concept of ecological radiation power was introduced to simulate the extraterritorial effects of carbon sequestration services in Qinling-Daba Moutainous area, the horizontal ecological compensation value was analyzed from the perspectives of both the compensating and compensated parties to promote the harmonious development of society and ecology in Qinling-Daba mountainous area.The results show that the total supply of carbon sequestration services in the Qinling-Daba Mountains is greater than the total demand, with the supply and demand of 20.42×107 tons and 68.77×106 tons respectively, and there exist significant differences in the spatial distribution within the region. The carbon sequestration services of Qinling-Daba Mountains are in surplus about 82.34×108t, demonstrating a significant extraterritorial effect of regional carbon sequestration services. The total horizontal ecological compensation payment is 1.25×108 yuan, and the fund distribution density from the compensation party is 285.75 yuan/km2 which is significantly different among cities and counties, and the average fund density is 585.22 yuan/km2. The study is an attempt to apply ecological radiation to ecological compensation, which enable the realization of the value of ecosystem services in areas where natural resources are plentiful and provide relevant scientific references for ecological compensation in supply areas.
