摘要
利用生存分析数学理论[1,2 ] 对 5个种源鹅掌楸苗期动态生命数据[3] 进行处理 ,构制了鹅掌楸苗期生命表及估计量方差表 ,绘制了 5个种源的死亡密度函数对比曲线和危险率对比曲线图 。
Using mathematical theory of survival analysis,Seedling dynamic life data of five L.Chinese seed sources have been dealt with in this paper.We work out the seedling life table of L.Chinese.The contrast curves of mortality density function and the dangerous rate of five L.Chinese seed sources have been drawn. We make survival analysis and put forward the ecological game.
