| In the situation of global warming, global carbon sinks is one of the core issues in the researches of global climate changes and the carbon sinks in forest ecosystem is an important part of the global carbon sinks. The estimation of forest carbon stocks is important to forest carbon sinks and global carbon sink. We take carbon content rate measurements of different organs of the arbor species and construct remote sensing model to obtain the carbon stock in Jiufeng Mountain based on collecting previous research material and field investigation.The over-ground part carbon rate of the five kinds of forests is0.5238,0.5078,0.4731,0.4726, and0.4771, respectively in Chinese pine, arborvitae, robinia, oak, and Quercus Variabilis Blume. The average carbon storage density of trees layer of the ground part by biomass method is31.7890t/hm2,26.6939t/hm2,22.7806t/hm2,21.4389t/hm2,20.1234t/hm2, respectively in arborvitae forest, robinia forest, Chinese pine forest, mixed oak forest, Quercus Variabilis Blume forest.The average carbon storage density of trees layer of the ground part by the remote sensing model is31.2787t/hm2,28.0188t/hm2,22.3613t/hm2,22.3147t/hm2,21.0749t/hm2, respectively in arborvitae forest, robinia forest, mixed oak forest, Chinese pine forest, Quercus Variabilis Blume forest. The carbon stock of trees layer of the ground part by the remote sensing model is0.005071Tg,0.004971Tg,0.003927Tg,0.000621Tg, respectively in arborvitae forest, Chinese pine forest, mixed oak forest, robinia forest. The average carbon storage density of Jiufeng Forest Park on the ground part of the tree layer is24.8188t/hm2and the ground portion of the tree layer of carbon storage value is0.014590Tg. The average carbon storage density of trees layer of the ground part by the remote sensing model and the value by biomass method are of little difference. Remote sensing model to estimate carbon stocks in forest carbon stocks estimation is a more convenient and effective way. |
