The Measurement Study On Carbon Baseline Storage Of The Carbon Sequestration Afforestation In Jiang Xia District

The forests is the main component of the land ecosystems,the storage estimates of forest carbon sinks is a foundation work on the carbon cycle and carbon dynamic analysis in the land ecosystems,which plays a very important role in the global carbon cycle research.The accurate research on the carbon storage of the forest ecosystems and carbon sinks function is of basic work,to appraises forest vegetation in the carbon balance have been of great significance.Baseline(the baseline) is the amount of carbon sequestration in the absence of the clean development mechanism carbon sinks projects,the measurement on the carbon storage baseline plays an important role for accurate estimates(pre-estimated)on the amount of net carbon sinks of the reforestation carbon sink project.In order to correctly assess the role of carbon sinks of the China Petroleum carbon sink projects in Wuhan's Jiangxia of China Green Carbon Fund.in support of the GPS technology,combined with the collection data of basic research,field data and field survey data of 2008 forest resources survey in Jiangxia District,the Masson pine and fir volume growth estimation model,the soil carbon measurement model were established, the amount of the baseline vegetation carbon storage were estimated,Measurement results accurately reflect the basic conditions of carbon storage under the baseline scenario of the reforestation carbon sinks in Jiangxia District.the main research conclusions are as follows:1,According to the measured plots data,the volume growth equation of the masson pine,and the fir in Jiangxia District were established. V_马=0.0671×D^1.8×H/1000 LgV_杉=1.758487×LgD+1.109542×LgH-4.165456 of which:V is volume(m³),D for diameter at breast height(cm),H is tree height(m)2,The carbon equation of soil organic storage of small compartment the carbon reforestation in Jiangxia District was established: C_i=SOCC_i×BD_i×Depth_i×Area_i of which:C_i for i small compartment reserves of soil organic carbon(tC),SOCC_i for i small compartment of soil organic carbon content of soil(gC/100g soil),BDi for the average soil bulk density(g/cm³),Depthi for the soil thickness(cm),Areai for the small area(cm²)3,The measurement results of carbon storage of the masson pine scattered wood biomass in Jiangxia District was 334.25tC,of which:above-ground biomass carbon storage was 278.54tC,below-ground biomass carbon storage fwas 55.71tC.The measurement results of carbon storage of the fir wood biomass was 29.78tC,of which: above-ground biomass carbon storage was 24.82tC,below-ground biomass carbon storage was 4.96tC.4,The measurement results of the total carbon sink of forest soil organic carbon storage in Jiangxia District were 26046.44 tC,the average organic carbon storage was 65.12 tC/hm²,of which:Liufang's soil organic carbon storage was 19026.71 tC,baoxie's soil organic carbon storage was 7019.72 tC.5,The measurement results of the CO2 emissions in the project boundary resulting from the use of mechanical fuel were 17.06t,however,The measurement results outside the project boundary resulting from the use of transport were 295.98t,total CO2 emissions were 313.04t.6,In this study,the carbon storage in carbon reforestation baseline vegetation were estimated,which the traditional parameters of the measuring carbon sinks were taken,but also the volume growth forecast equation of the Masson pine and the fir were established. This article explores the measurement of carbon storage under the baseline scenario of the reforestation carbon sinks,which is expected to provide a new estimation method of forest carbon sinks,to provide a reference on regional eco-environmental construction in Hubei Province under the conditions of the global climate change and the development of regional forest ecosystem carbon Department of Management.
