| 摘 要： | 当环境中可利用的资源低于种群最佳生长需要时,种群内个体之间就会产生竞争.竞争常发生在邻体植物之间,植物地上部分和地下部分的竞争范围不同.目前,有很多度量竞争强度和确定竞争范围的方法,本文通过对不同方法的比较分析,提出了更具有说服力的方法. |
| 关 键 词： | 太白红杉 邻体竞争 竞争指数 竞争范围 |

| Abstract: | Competition among trees within a population exists when resource availability falls below the sum requirement of the population for optimal growth. Competition for both aboveground and belowground resources takes place over different-sized zones. It is important to choose the suitable competition index to study the competition intensity. Through analysis and simulation using sample plot data, a competitive index objectively reflecting the competition and growth pattern of Larix chinensis has been selected. The results have showed that the improved competition index and method for qualifying the competition zone are more suitable for studying the neighborhood competition. |
| Keywords: | Larix chinensis neighborhood competition competition index competition zone |
