Growth Model And Carbon Ripening Of Larix Gmelinii Plantation

Taking the Larix gmelinii plantation as an example,the growth model of forest biomass and carbon storage was studied to provide a time series estimation of forest biomass and carbon storage on a regional scale,and to provide a reference for the methodological support of forest carbon sink measurement..Based on the survey data of the second forestry survey and design institute of Inner Mongolia(referred to as the Second Institute of Forestry)in 2012-2013,45 fixed plots and 130 standard trees were selected to establish the DBH and tree height of the Larix gmelinii plantation.The growth equation of Larix gmelinii plantation was studied by the equation of volume growth.Based on the biomass source method and the carbon content of the Larix gmelinii trees measured by the team,the carbon storage growth model of Larix gmelinii plantation was constructed,and the carbon storage growth curve of Larix gmelinii plantation was evaluated.Pine plantation carbon mature age.It provides theoretical basis and scientific guidance for the management of Xing'an larch plantation in Daxing'anling forest area and the development of carbon sink work.The main conclusions are as follows:(1)Finally,detennine the tree height growth equation of Larix gmelinii plantation:H=22.588(1-e-0.0321)(R2:0.912);9.83(2)The DBH growth equation of Larix gmelinii plantation:D=26.94e9.83/1(R2:0.76);(3)The growth equation of the Larix gmelinii plantation:V=0.399*e33.777/1(R2:0.692).(4)Using carbon as the dependent variable and carbon storage as the independent variable,the carbon storage growth model of Larix gmelinii plantation was constructed.C?0.5*(209.514*e29.584/t)The carbon storage mature age of Larix gmelinii plantation was 30 years,and the average carbon accumulation was 1.303 t hm2.
