摘要
该文首次尝试把种群生态学中的内禀增长力（rm）的概念用于人口。并计算了壮族人口的净雌生殖率R。（3．1375／♀），平均世代生育历期T（30．71年）、自然增长力rm（0．0372）、周期增长率λ（1．0379）等．研究发现缩短生育历期比增加净雌生殖率对人口的rm的贡献要大得多．因此，提倡晚婚晚育比少生更重要．
This paper reports the attempt to apply the concept to the intrinsic growthrate of population ecology. The net reproductive rate per female of 3. 1375,the average period of generation reproduction of 30. 71 years,the innate growth rate of 0. 0372 and thedouble time of 18. 6330 years .of Zhuang population,were calculated by means of Leslie equation. The research results also imply that the decreasing generation period is more influential than the increasing net reproductive rate to growth of Zhuang population.
