摘　　要：针对小波去噪的特点,研究了现有小波去噪质量评价方法的实际应用效果。通过实验分析与比较,得到了现有5种小波去噪质量评价方法的实际评估能力。Wavelet transform has played an important role in the field of surveying data processing, as the noise can be eliminated effectively on the basis of wavelet decomposition and reconstruction. Currently, the research of wavelet de-noising mainly focuses on the development of wavelet de-noising methods, however, the validity assess- ment of wavelet de-noising result should be indeed taken into account. Seeing that, a comparative study on validity assessment methods of wavelet de-noising is down. The practical performance of existing validity assessment meth- ods is obtained through a series of experiments.
