基于FORECAST模型模拟造林密度对杉木人工林碳储量的影响
Effect of Plantation Density on Carbon Storage of Chinese Fir Plantation Based on Simulation of FORECAST Model
摘要
Abstract
FORECAST model was used to simulate the long-term effect of different plantation densities on the carbon fixation of Chinese fir plantation, in order to attain the goal of optimizing the management of Chinese fir plantation. The results showed that: along with the increase in plantation density of Chinese fir, the aboveground biological carbon storage, underground biologi-cal carbon storage, total biological carbon storage, soil organic carbon storage, and total carbon storage all increased; but these indexes tended to be stable when the plantation density exceeded 3333 plant/hm2 . When the plantation density was 1667～2500 plant/hm2 , the total biological carbon storage in each rotation felling period decreased. The high-density afforestation could cause the violent competition of sunlight, water and fertilizer among trees, which was not conducive to the carbon accumulation in forest ecosystem. According to different site conditions, the suitable planting density of Chinese fir was 2500～3333 plant/hm2 .关键词
