中文摘要：

纳西东巴文字是一种比甲骨文还要原始的图画象形文字,该文针对大量纳西经典古籍资料需要录入、整理、分析的需要,设计一种普通用户即可使用的基于拓扑特征的输入方法。首先针对纳西东巴象形文字的1 561个基本字形的五个拓扑特征-块数、孔数、端点数、三叉点数和四叉点数进行了统计和分析,然后基于Java程序结合TTF字库文件进行了测试,证明了该方法可行。统计结果表明,50%以上的纳西东巴象形文字通过这五个特征可以唯一识别,80%以上的东巴文字通过该方法识别时重复数不高于4,人工输入、识别的效率较高,为纳西东巴象形文字的输入方法提供一种新的思路。

英文摘要：

Naxi Dongba characters are a kind of pictographs that is even more primitive than Oracle pictographs.As there is a large number of ancient Naxi classical books are needed to be protected and input into the computer system,an input method based on the topological characteristics of Dongba characters is designed for ordinary users.Firstly,the five basic topological features including number of blocks,number of holes,end points counts,threeconnection-points counts and four-connection-points counts of 1,561 Naxi Dongba characters are after statistics and recorded.After that,this method is tested by a Java-based program combined with TTF font file and it proves that the method is feasible.Statistics show that more than 50% of Dongba pictographs can be identified uniquely through these five characteristics and more than 80% of them can be identified by this method with no more than 4repetitions.It provides a new way to input Naxi Dongba hieroglyphs with the manual input and with high efficiency of identification.
