模拟楠木杉木人工混交林不同混交比例对净生产力和碳储量的影响
Simulation of the Effects of Various Mixing Proportions on NPP and Carbon Storage in the Mixedwood Plantations of Phoebe bournei with Chinese fir
摘要
Abstract
Using forest ecosystem model FORECAST ,the net primary productivity ( NPP) and forest car-bon storage in the mixture of Phoebe bournei with Chinese fir were simulated with various management scenarios including different site qualities and mixing proportions (5∶1,4∶1,3∶1,1∶1 and 1∶3 between Phoebebournei and Chinese fir) over the simulation period of 300 years.The simulations suggested that the total cumu-lative carbon storages in both stem and above-ground forest components were the greatest with the mixing pro-portion of 3∶1.The soil carbon storage in the pure Phoebe bournei forest and the Phoebe bournei-Chinese fir mixed forests with mixed proportion of Phoebe bournei being higher than 1∶1 was on the increasing trend over the simulation period of 300 years,while those in pure Chinese fir forest and the Phoebe bournei-Chinese fir mixed forests with the mixed proportion of 1∶3 was on the decreasing trend .Compared with those in low quali-ty sites,the carbon storages in high quality sites were higher .It might be concluded that the best mixed propor-tion of Phoebe bournei with Chiense fir is 3∶1,which is beneficial for sustaining or improving soil carbon stor-age in the long run .关键词
