Studv On The Potential Of Chinese Ifr’s Carbon Supply In Zhejiang Province

With the global concern of climate change, as an important means to address climate change，forest carbon sequestration will play a more important role. In this paper, on the basis oftheoretical analysis the influencing factors and Summary of forest carbon sinks market supplypractice, Select representative species Chinese fir in Zhejiang, simulation the supply potential offorest carbon sinks by an improved Hartman model. Then based on the existing fir acreage, landuse change, land suitable for planting three scenarios to simulate the supply potential of ZhejiangProvince as a whole fir forest carbon sinks, and then put forward a policy tool to promote thesupply of forest carbon sinks.The main conclusions are as follows:（1）Use of the supply in microeconomics theory,to analysis of factors affecting the supply offorest carbon sinks..The main factors include: the cost of production, forest management, technical,industrial emissions and carbon capture and sequestration costs, government policies and thenatural conditions. Timber price changes will impact the supply of forest carbon sinks.（2）Sum up the supply of forest carbon sinks under the Kyoto and non-Kyoto rules ofpractice and development trends, we found that:Kyoto rules-based international carbonsequestration market has just started, the transaction size is small, the rapid development ofdomestic carbon exchange markets, has become an important provider of market of the world’scarbon sinks. Future forest carbon sequestration under the Kyoto rules the market will not stagnate,but afforestation and trading rules may change; domestic forest carbon sequestration voluntarymarket is the rapid development and huge market potential in the future.（3）using an improved Faustmann-Hartman model to simulation carbon sequestrationoptimal rotation and land expectation values in per unit area by the price changes.Existing firbusiness objectives in a business objective to increase forest carbon sinks, forest carbon sinks andthe proceeds of the forest management business decisions have a major impact. Improve carbonsequestration price of the fir operating rotation did not produce a significant impact, but asignificant increase in forest land value, improvement of forest value will make forestmanagement more land for timber production, thereby increasing the timber supply. At the sametime, the increase in the value of woodland may reduce the chance of forest land converted toother uses, such as agricultural land. And even cause some agricultural land into land for forestry.（4）Zhejiang fir forest carbon sequestration supply potential is huge. Based on the existingfir acreage, land use change, land suitable for planting three scenarios to simulate the supplypotential of Zhejiang Province as a whole fir forest carbon sinks.0yuan/ton to450yuan/tchange when the price of carbon sinks, based on existing acreage fir forest carbon sequestration supply potential minimum of48,203,000tons to55,575,000tons. Supply potential of theappropriate land-based carbon sinks, and310.62million tonnes to358.12million tonnes. Firforest carbon sinks in Zhejiang Province, the largest supply potential should be in the rangebetween the consideration of land use change scenarios and appropriate supply potential in theland scenario.（5）Suggestions to increase the supply of forest carbon sinks from the following areas:expanding the area of forest land, improve land use efficiency; strengthen forest management, toimprove the carbon sequestration capacity per unit area; stable forest carbon sequestration ofproperty rights, encourage forest managers operating carbon sink forestry; actively promoteforestcarbon sink market.
