The invention relates to a simple spelling input method for Chinese characters on a computer alphabetical keyboard, which comprises the following steps: (1) a Pinyin coding method, namely, coding an initial consonant and a final sound respectively, and expressing the initial consonant and the final sound by using a letter; (2) a stoke coding method, namely, using a Pinyin code of a first character of a stroke name as a stroke code; (3) a radial coding method, namely, using a Pinyin code of a first character of a Chinese character radial name as a radial code; (4) a component coding method, namely, dividing Chinese character components into four types, using a Pinyin code of a first character of each type name as a component code, splitting the components into an A part and a B part, and coding the A part and B part according to acoustic codes of the A part and B part; (5) a single character coding method, namely, summing the sound code, the A part acoustic code and the B part acoustic code of the character into codes of a single character; (6) a coding method for Arabic numerals, namely, using pronunciation and spelling codes of the Arabic numerals as codes of the numerals; and (7) coding Chinese characters or Arabic numerals to be inputted according to the coding methods, and stroking corresponding letter keys according to the codes of the corresponding Chinese characters or the Arabic numerals. By adopting the method to input the Chinese characters, the keystroke times is less, and the input efficiency is high.
