| 摘 要： | 选择 4种有代表性的植物邻体竞争指数 ,分析了竞争对日本落叶松 (L arix leptolepis)试验种群的个体生长速率和死亡概率的影响 ,发现在本试验条件下 ,引入竞争指数不能明显改善对生长速率的预测效果 ,但用竞争指数可以较好地预测个体于 1个月内在竞争压力下死亡的概率 ,从而为构造植物生长模型时处理个体死亡问题提供一个有益的定量化思路

| Abstract: | Four competition indices were used to analyze the effects of competition among neighboring tree individuals on growth rate and probability of death of tree individuals, based on data from nursery experiments of Larix leptolepis populations. Probability of death of trees was accurately predicted by the competition indices, while no obvious correlation was found between competition indices and growth rate. The correlation of probability of death and the competition indices may contribute to future individual based plant growth models. |
