摘　　要：采用野外实地调查和拟合二次方程（QUADRATIC）分析建立曲线估计模块（CURVE ESTIMATION）的方法对顶坛花椒的生殖力进行了研究。结果表明：当顶坛花椒处于5～9龄时它的生殖力出现峰值，也就是说它的生殖力达到最大值；在海拔为600m左右的地段，顶坛花椒具有最大的生殖力；同时还发现花江地区的顶坛花椒种群已经显示出老龄化的迹象。在为顶坛花椒的种植提供科学指导的同时也可作为脆弱的喀斯特生态环境恢复与重建的科学依据。In this paper we use the methods of field survey estimation, then give further evidence in order to prove this and analyze the data with the quadratic and curve view. The results show the peak value of its reproductive age is during 5 -9 years old, that is to say that the fecundity of the Zanthoxylum Planispinum var. dingtanensis reached its maximum at this age period, while at an altitude of 600 m, the Zanthoxylum Planispinum var. dingtanensis have the maximum fecundity. At the same time, we also find the population of Zanthoxylum Planispinum var. dingtanensis in huajiang area aging. The paper provide not only scientific planting guide for Zanthoxylum Planispinum vat. dingtanensis but scientific evidences for restoration and reconstruction of the fragile karst eco-enviroment.
