中文摘要：

对Logistic序列进行研究,利用Matlab数值模拟,通过计算不同初值、不同参数对应的混沌序列的计盒维数,得出结论：只要在数据充分的情况下,Logistic系统的分形维数基本由参数λ决定,与系统初值无关;同时计盒维数并非像熵一样随Logistic系统的参数λ增大而增大.

英文摘要：

Using the Matlab numerical simulation, the box counting dimension calculation of different initial value, chaos sequences with different parameters, we have research on the logistic sequences and draw results： The fractal dimension is decided by parameter A mainly and it is irrelevant of initial value . At the same time, the box counting dimension does not increase like entropy with the parameters of logistic system.
