Effect of Different Control Methods on Carbon Sink Function of Artificial Pinus kesiya var langbianensis Plantation
摘要
Abstract
Through surveying the standing forest of Pinus kesiya var langbianensis under different conditions, namely,without control, chemical control,physical and mechanical control as well as normal one,the biomass,carbon rate and carbon content of different components of P. kesiya varlangbianensis were determined, moreover,BEF,biomass,carbon storage,carbon density and carbon sink function of 4 kinds of forests were estimated. The result showed that the tree biomass,carbon storage of the tree,the soil and the forest in Jinggu County were 1.51 × 107 ,7.83 × l05 ,1.42 × 106 and 2.28 × 106 t,respeetively,these data showed carbon sink function of P. kesiya var langbianensis forest was strong; BEF of the 4 kinds of forests are from 0.410 2 to 1.250 O; the biomass and carbon storage of different components from high to low were：trunk ＞ root ＞branch ＞leaf; the organic carbon storage of the forests from high to low were：soil horizon ＞ woodyard ＞ litter layer ＞bush layer ＞ field stratum. The tree biomass and carbon storage,carbon density of the forest and the soil dropped 15.80 kg,8.10 kg,47.04 t/hm2 and 32.66 t/hm2 ,respectively after Dendrolimus kikuchii Matsumara was harmed. They raised 9.70 kg/6.90 kg,5.00 kg/3.62 kg,25.93 t/hm2/19.50 t/hm2 and 17.93 t/hm2/13.09 t/hm2 ,respectively after the forests were controlled by chemical or physical ways.关键词
