Study On Economic Benefits Of Forest Carbon Sinks

With the "Kyoto Protocol" come into effect, forest carbon sinks become an important way to alleviate the greenhouse effect. Improve the effectiveness of the forest carbon fixation and vigorously tap the economic value of forest carbon sinks have important strategic significance. The paper took the Yong’an city of Fujian Province for an example, evaluated the economic benefits of forest carbon sinks, selected the dominant tree species of forest carbon sinks projects, and then empirical analysis the impact factors of forest canbon sinks, in order to provide decision basis for the forest farmer in participating forest canbon sinks projects and provide a reference for choosing tree species of forest carbon sinks projects and developping government policies.Firstly, the paper studied the economic benifits of forest carbon sinks basing on general combing foreign research and practice of forest carbon sinks results, also basing on combing the domestic practice and research such as the importance of forest carbon sinks, the research measurement methods of forest carbon sinks, the cost of forest carbon sinks, the price of forest carbon sinks, the economic value of forest carbon sinks, the forest carbon markets and trading ststus.Secondly, the paper collected the data through participatory surveys, networks and relevant statistical yearbook. In order to compare the economic benefits of forest carbon sinks of Cunninghamia Lanceolata Forest, Pinus Massoniana Forest, Eucalyptus Forest these three tree species for determining which species is more appropriate as a carbon sinks project, the paper measured the forest carbon sinks, carbon sequestration costs, carbon sinks breakeven point and carbon economic benefits in basis on the data of 54 plots in Yong’an, Fujian Province. Further more, the paper studied the relationship between investor controllable factors and forest carbon sinks in using Grey Relational Model by the inventory data of the second to seventh Fujian forest resource, and then determined the correlation of the impact factors and sorted them. Through analysis, got the following conclusions:â‘ The forest carbon sequestration of Cunninghamia Lanceolata, Pinus Massoniana, Eucalyptus forest near mature forest and mature in Yong’an,2008 （carbon sequestration, including the amount of forest biomass, forest and woodland vegetation for carbon sequestration）: carbon content of Cunninghamia Lanceolata forest was 2494603.86MgC; Pinus Massoniana forest was 5249239.90MgC; Eucalyptus forest was 943129.56MgC. Meanwhile, according to the species age scale, the paper calculated the annual amount per unit area of carbon sequestration order: Cunninghamia Lanceolata > Eucalypt> Pinus Massoniana. Among them, the Cunninghamia Lanceolata forest was 0.2315 MgC / Mu?Year; Pinus Massoniana was 0.1878 MgC / Mu?Year; eucalyptus is 0.2061 MgC / Mu?Year. And then calculated the summary value of these three species was 0.27 billion in Yong’an City in 2008, of which Cunninghamia Lanceolata forest’s value was 295 billion; Pinus Massoniana forest’s value was 6.21 billion; Eucalyptus forest’s value was around 1.12 billion.â‘¡Calculated the average annual costs for carbon sinks in using replacement cost method by the survey data of 54 samples in 3 samples town of Yong’an about the three species: Eucalyptus forest> Cunninghamia Lanceolata forest> Pinus Massoniana forest, of which Cunninghamia Lanceolata forest was 38.89 yuan / mu.a, Pinus Massoniana forest was 25.46 yuan / mu.a, Eucalyptus forest was 96.46 yuan/ mu.a. Transaction costs was 26.82 yuan / mu which came from the CDM project of Guangxi River watershed reforestation for Eucalyptus forest.â‘¢Assuming the tree cutting without regard to income or ecological compensation income, the three species of economic efficiency as carbon sinks of Yong’an City, Fujian Province: Cunninghamia Lanceolata forest was -391.65 yuan / mu; Pinus Massoniana forest was -165.73 yuan/ mu; Eucalyptus forest was -1658.08 yuan / mu. The average annual investment return of three tree species was: Cunninghamia Lanceolata carbon sink forest was -0.87%; Pinus Massoniana carbon sink forest was -0.25%; Eucalyptus carbon sink forest was -3.25%. Therefore, from the economic point of view, choosing the Pinus Massoniana forests as the specie of carbon sinks project in Yong’an City was more appropriated. Meanwhile, the sensitivity analysis obtained by carbon sequestration cost of each tree species was significantly affected by carbon sink trading price, the average annual per unit area and forest carbon sequestration cost.â‘£Empirical studied the forest carbon sinks by using the method of system analysis from Gray system theory, meanwhile choosed the correlation factors of which the forestry producers can exert a more significant role in it. Sorted of forest carbon sinks and carbon sequestration factors the correlation basing on the second to seventh forest inventory data: R₂> R₃> R₄> R₅ > R₁> 0 （R₁=0.777317;R₂=0.968984;R₃=0.967403;R₄=0.964113;R₅=0.963244）, in which R₁, R₂, R₃, R₄, R₅, respectively the correlation between forest carbon sinks and forest investment in capital construction, afforestation areas, timber production, the affected forest area, forest pest and rodent area. and carbon storage in place the correlation.Finally, the paper put forward policy recommendations which based on research finds:â‘ Make reasonable carbon subsidies, improved the financial management of forest carbon;â‘¡Improve the market trading system to reduce market transaction costs;â‘¢Universal knowledge of carbon sinks to play the role of government services;â‘£Put relevant measurement standards and regulations.
