The Analysis Of Forestland Benefit Possible Changes Of Different Types In Carbon Trading Situation

Climate change has become one of the hot topic in the international community, In order toseek effective measures to slow global warming on a global scale,the development of Carboneconomy has become an inevitable trend. Forests can not only produce great economic effect, butalso has great ecological effect. For considering the environmental effects of forest management,The optimal rotation management can make the forest ecological benefit maximize. Especiallyunder the circumstances of climate warming, People pay more attention to co2emissions cutting,Increasing forest carbon sink has become one of the most important measures of carbon reduction,therefore, forest carbon sequestration effect is also more and more get the attention of people. Thisarticle selects Chinese fir as the representative tree species, Based on the field survey data ofzhejiang province, Under the current forest management strength, Analysising the may be changeof forest benefit under the composite goal.First of all, Based on field survey data, analysising forestland operating cost-benefit underthe single business objectives, analysising forestland operating cost-benefit of different siteconditions and different scale, Based on the optimal rotation period model forest land cost-benefit analysis；The second, Simple analysis the path of achieving forest carbon sink returns hascarried on the forest benefits, From the mechanism, achieving forest carbon sink returns hascarried on the best rotation period, net present value, expected value and internal rate of returningunder the compound management goal;At last, Based on field survey data, in the current carbonprices as well as different carbon prices, analysising optimal rotation period, net present valueexpected value and internal rate of return of the forest management under the compoundmanagement goal, And comparing with the single management goal.Research shows that:(1) In the current forest management strength and the current carbon price, the optimalrotation period of forest management is the same under the Compound management goal and thesingle goal, In the current carbon price，achieving the carbon sequestration benefits will not affectthe rotation period of forest management., While the carbon price rising to a certain degree, Dueto the carbon price is higher, make the best rotation period lengthen.(2) Under the compound management goal, As the change of the carbon price, forestland income changes. The carbon price rises ceaselessly, net present value, expected value and internalrate of return all showed a increasing trend.(3) Under the compound management goal, achieving the carbon sequestration benefits, Netpresent value, expected value and internal rate of return all have increased than the single goal.
