Evaluation Of Forest Carbon-sink

Increasing density of carbon dioxide in the atmosphere is one of the important factors that make the globe warmer. Therefore, it has been becoming a focus that how to control the release of the carbon dioxide and decrease the density of the carbon dioxide in the atmosphere. Obviously, forests play an important role of absorbing and fixing carbon dioxide. The original intention of the research is just to evaluate the role of the forests. And this dissertation try to reach the following targets: First, discussing the theory on the evaluation of the forest carbon-sink; second, probing the method of the evaluation of the forest carbon sequestration; final, using above theory and method to evaluate the artificial wood carbon-sink of the Sanbei Shelterbelt Project in Heilongjiang.According to the characteristics of the forestry project, this dissertation synthetically uses correlated knowledge, such as forestry, economics, ecology, environmental economics, resource economics and assets evaluation, and analyses and probes reasonable and feasible theory and method on evaluation. At the same time, this dissertation evaluates the artificial plantation carbon-sink of the first stage of the Sanbei Shelterbelt Project in Heilongjiang through analyzing and dealing with the collected data. Eventually, this dissertation tentatively makes the following viewpoints and conclusions:1 The connotation of carbon-sink can be concluded as follows: carbon-sink is a kind of function by which carbon dioxide can be absorbed and fixed; carbon sequestration is a kind of process, action and mechanism by which carbon dioxide can be cleared from the atmosphere; carbon sequestration is a sink in which carbon can be collected and saved; carbon-sink symbolizes a state in which carbon is more absorbed than released.2 Forest carbon-sink has the characteristics of the assets. Furthermore, its connotation is eco-assets, resource assets and intangible assets.3 Forest carbon-sink has some economic characteristics: first, forest carbon-sink is scarce, and the scarcity is either an absolutely scarce deposit or a kind of relative scarcity that the development of the industry and the other use of the forest make; second, forest carbon-sink has the characteristics of the public goods; final, forest carbon-sink has a positive externality.4 As for the methods of estimating amount of the forest carbon-sink, the method of continuous function of biomass expansion factor synthetically indicates the changes of...
