人工林生产力和生物量动态的计算机模拟

In order to provide a theoretical basis for fast-growing and carbon sequestration of plantation, we studied the influence of the planting density, spatial distribution of plants and seeding size inequality on the productivity, accumulated biomass, maximum of standing biomass and carbon storage, and drew the survival curves of the population by using individual-based and spatially explicit model. Results showed that density、distribution pattern and seeding size inequality have significant impact on the growth and competition of plantation, resulting in plantation productivity, biomass and carbon storage changing. Maximum productivity, accumulated biomass, maximum of standing biomass and carbon storage under uniform distribution were larger than under random distribution, and increased with planting density increasing and seeding size inequality decreasing, but delayed the time to reach peak productivity and the maximum of standing biomass of plantation under uniform distribution . Therefore, plantation uniform planting with moderate size inequality seeding and reasonable density is more appropriate.
