Arbor Carbon Storage Of Different Reclamation Patterns In ATB Opencast Mine Dump Based On Biomass

As global warming sharpening，the amount of carbon dioxide In the atmospherebecome more and more higher, The present study consider that planting trees is one ofthe most economical way to reduce the amount of carbon dioxide.A lot of coal beminen every year in our country, and coal mining will destroy the surface of theoriginal landscape and ecological system, makes a large amount of carbon releasedinto the atmosphere.Through land reclamation and ecological reconstruction ondamaged land, can make the carbon dioxide released into the atmosphere back intothe ecosystem,therefore,recovery of reclamation land vegetation has great significanceon carbon storage. This article take the plots of ecological reclamation land of ATBOpencast Coal Mine Dump for study.According to the field survey data of vegetation,using forest stock volume method derived forest biomass and carbon sinks, Thenappraise every reclaimed land.The research results as follows：(1)From the perspective of tree’s volume：there are four sample plots, SⅠsample plots(in Locust×pine reclamation mode),SⅢsample plots(in Locust×elm×ailanthus reclamation mode), SⅣsample plots (in Locust×pine reclamation mode)and SⅤsample plots (in locust reclamation mode), the highest density of tree’svolume is SⅣsample plots,it reached by45.00m3·hm-2. In the next place, the densityof tree’s volume in SⅠsample plots is32.61m3·hm-2, which was far less than theSⅣ sample plots. The density of tree’s volume in SⅢsample plots was24.39m3·hm-2, The density of tree’s volume in SⅤsample plots was21.44m3·hm-2,whichis the smallest in these four plots. The numerical relationship among the four sampleplots was SⅣ>SⅠ>SⅢ>SⅤ.(2)The numerical relationship of Biomass density of the four sample plots wasSⅣ>SⅠ>SⅢ>SⅤ,the biomass of SⅣsample plots was47.76t, the biomass of SⅠsample plots was39.69t,the biomass of SⅢ sample plots was26.76t,but the biomassof SⅤsample plots was just24.53t.The biomass denity of SⅢsample plots underLocust×pine reclamation mode was1.53time as much as the biomass of SⅤsampleplots. (3)The final results showed:the numerical relationship of the capacity of Carbonstorage among these four sample plots was SⅣ>SⅠ>SⅢ>SⅤ.The sample plotswhich has the highest carbon density was SⅣ, the density of carbon storage of thissample plots was27.54t·hm-2,higher than the capacity of national average carbonstorage of artificial forest,which was22.17t·hm-2,lower than the capacity of averageforest carbon storage of Shanxi Province,which was31.75t·hm-2,the lowest densityof carbon storage of SⅤsample plots was17.95t·hm-2. The total capacity of carbonstorage of theese four The reclaimed land was77.14t, the density of carbon storagewas21.43t·hm-2.The calculation result of tree’s volume, forest biomass and the capacity ofCarbon storage show that:the effect of pure Locust forest perform worst in these foursample plots,Compliance with the Previous research result that the effect of mixedreclamation mode perform better than pure forest. The effect of SⅣsample plotswhich in Locust and pine reclamation mode was the best in these four sampleplots.The planting tree species and planting density has influence on the rehabilitationeffect. The capacity of Carbon storage of SⅠsample plots、SⅢsample plots and SⅤsample plots is lower than the national average capacity of carbon storage of artificialforest, so we can take some measures to increase the capacity of carbon storagesample plots.
