| 摘 要： | 以种群生命表和生存分析理论为基础,采用"空间代时间"的方法,编制种群静态生命表,绘制存活曲线、亏损率曲线、死亡率曲线和生存分析函数曲线,分析罗浮栲(Castanopsis fabri)种群动态变化趋势。结果表明,罗浮栲种群存活曲线趋于Deevey-Ⅰ型;存活数随龄级增加呈现递减趋势,Ⅵ龄级后变化幅度较大;亏损率、死亡率和危险率随龄级增加呈现逐渐增长趋势,在Ⅴ龄级前的变化幅度较小,Ⅴ龄级之后增长迅速;种群生存率函数值随龄级增加而减少。 |
| 关 键 词： | 种群 生命表 存活曲线 罗浮栲 |

| Abstract: | Based on the theory of the population life table and the survival analysis, using the method of spatial series substituting for time series, the population static life table was established and survival curve,lose rate curve, mortality rate curve, survival analysis functions curve were drawed for analysis of the population dynamics. The results showed that the survival curve of Castanopsis fabri population tended to Deevey-Ⅰ type. The survival number of Castanopsis fabri population decreased as the age class increased, tending to significant decreasing after the Ⅵ age class. The loss rate and mortality rate increased as the age class increased, appearing the rapid increasing after the Ⅴ age class. The survival rate function decreased as the age class increased. |
