Life table and sex ratio of Nageia nagi
摘要
Abstract
In order to better guide introduction, population protection and provenance selection of N.nagi population, the space time method and smoothing technique were used in life table analysis, and the distribution of female and male population were analysised.Results showed that the N.nagi population age structure was increasing type.The three peak population mortality rate and loss rate of N.nagi were appeared at 3rd, 5th and 7th age class, respectively.The survival curve of N.nagi population can be described as Deevey-Ⅱtype.The N.nagi male individual in different slope positions ranked from high to low were uphill position, middle slope position, and downhill, which site quality grades were Ⅳ, Ⅲ, andⅡ.The law of female individual in different slope position and site quality grades and the male individuals were the complete opposite to N.nagi male individual.关键词
