Climate change is one of the most concerning global environmental issues, which directly affects both of the natural ecological system and social economic system. Global climate change is the enormous threat and a major challenge the humanity facing. Forests play a very important role in adapting to climate change. Forest system provides numerous ecological services, which made great contributions to mankind. However, forest owners did not get a corresponding return because of the externality of the forest ecological value. The issue to which the governments and academics pay close attention is how to quantify the ecological value of the forest which reflected to the forest owners or the producers’ benefits. Forest is the largest terrestrial organic carbon pool, because growth of tree is also a process of CO2absorpted, and the process can effectively reduce the concentration of atmospheric CO2. To adapt to climate change, one of the issues is how to value the forest carbon sequestration, which reflected to the carbon owner or the producer, and how to form effective price mechanism.Firstly, in the paper the current climate change trend was briefly described, and a low carbon economic model was built according to the KAYA formula. The results show that: in2007, the net emissions of carbon was calculated to be142Mt totally in Jiangxi province and average carbon emissions of per capita was3.25tons/year.The carbon emissions offset by Jiangxi forest vegetation in the region were calculated to be26.5Mt/year, and the contribution rate that forest vegetation helps to neutralize or reduce carbon emissions was18.7%.Then, in contrast to a variety of methods of calculation of forest carbon sinks and carbon sequestration, forest stock volume expansion method was selected to calculate the Jiangxi forest carbon sink and carbon sequestration. The results were that:In2010, carbon sequestration is587.597Mt in Jiangxi forest; if the average annual growth of the forest growth rate is4.03m3/hm2in Jiangxi, and taking into account many factors, forest carbon sequestration would be901.709Mt in Jiangxi in2020, the Jiangxi Province of the total forest carbon sink potential would be314.112Mt form2010to2020(10years); and capacity of an annual carbon sink is31.411Mt form2010to2020(10years).Secondly, based on the theory and practice of the forest carbon sink value appraisal and the Economic Characteristics of forest carbon sinks, this paper combined with the estimation method of forest carbon sequestration and calculated the value of Jiangxi province forest carbon sequestration. According to the Jiangxi forest conditions, the amount of forest reserves in Jiangxi Province in2020was calculated to be750million m3, and the average annual forest carbon sink capacity could be achieved31.411MtC in the period of2010-2020. During this period the average annual economic value of forest carbon sinks reached2.145billion yuan on68.3yuan/t C price; its economic value reached9.58billion yuan at the price of305yuan/t C; and the economic value would be32.165billion yuan at the price of1024.5yuan/t C.Thirdly, based on the economics of natural resources and environmental, microcosmic economics and sustainable development theory, the paper also combined with the actual survey with the investigation of general market value formation process. On the survey of304urban residents,72enterprises,52forest farmers and46forest owners, the function of the supply and demand of forestry carbon sink was constructed under different scenarios. The result showed that, trading price of carbon sink will change in different situations, and the demand curve has greater elasticity in voluntary scenarios, of which the point (Qo, Po) of equilibrium price is (87553.03,23); The curve will move to the right, of which the point (Qo, Po) of equilibrium price is (105873.47,24.02) in inspiring scenarios; And the demand curve of carbon sink of individual and enterprise is almost a vertical line on tax situation, and demand tends would be more rigid, of which the point (Qo, Po)of equilibrium price is (67176.05,14.75). Market prices equilibrium of supply and demand of forest carbon sink land in different scenarios was that:point (Qo, Po) of equilibrium price is (1545,695.5) in voluntary scenarios; point (Qo, P0) of equilibrium price is (4698,771.56) in incentive situation; point (Q0, Po) of equilibrium price is (2518.5,716.52) in tax scenario. Based on the function of demand and surply of forestry carbon sink, and the price balanced model which combined with the trade data of the Southern Forestry Property Rights Trading Market in December2011, the prices of the forestry carbon land land the forest carbon sink were caculated, of which the price of no forest land was1140yuan/hm2; and the price of forest cabon sink land is4308yuan/hm2when the area remains of the circulation is constant; and the price of forest land is at1140~4308yuan/hm2.the price of forest carbon sink is276.5yuan/m3; if the production and sale of the forest carbon sink equivalented operation before felling tree, the price of forest carbon sinks is230.04yuan/t which was calculated through forest stock volume expansion method.Finally, the forest carbon sink metering method and the transaction price formation process were combinated in Jiangxi, the development strategy of forest carbon sink was designed, and the operation and management mode of the Poyang Lake Ecological Economic Zone carbon fund was explored in this paper.
