| 摘 要： | 在DNA序列郝柏林图形化表示方法的基础上，提取出表征图形特征的两个量化参数：信息熵和分形盒维．对人类基因序列和非基因序列各50个片段进行郝柏林图形化和特征参数的提取，结果表明：这两个参数具有区分人类基因序列和非基因序列的统计规律．

| Abstract: | Two parameters,information entropy and box dimension of fractals,are extracted from Hao's graphical representation of DNA sequences.This method is applied to human gene and non-gene sequences,50 sample segments apiece.The statistical result shows that these two parameters may be used to distinguish gene sequences from non-gene ones of human genomes. |

| Keywords: | DNA sequences Hao's graphs information entropy box dimension of fractals statistical characteristics |
