基于个体植物生长模型的森林动态演替模拟
Forest dynamic succession simulation based on individual plant growth model
摘要
Abstract
The calculation and simulation of forest dynamic succession is always a significant issue of forest ecology. Different from traditional macroscope simulation way, in this paper, we proposed a bottom-up simulation approach based on individual plant growth model. The parameterized individual plant growth model was constructed firstly considering three influencing factors on plant growth including plant internal attribute, external environment and neighborhood competition, so as to simulate the growth changes in various environments of plant. Under such circumstance, a large amount of plant individuals in a forest would be calculated by the ergodic and iterative way to simulate the growth succession phenomenon in whole forest region. The results of experiment show that the approach in this paper could simulate the dynamic changing effect influenced by complex external environment of vegetation, including various typical rules of vegetation succession such as natural thinning, species competition and species succession.关键词
