| Abstract: | Weibull distribution is one of the most important tools for the study on D.B.H. distribution law of trees.Genetic Algorithms is used to optimize weibull distribution model,and weibull model is used to study the D.B.H. distribution law of Chinese fir plantation.The results show that acceptance rate of fitting by optimal fitting weibull model is above 80%,which means Genetic Algorithms is a useful tool for fitting on non-Linear model. |
