Abstract： Karez， together with the Great Wall and the Beijing-Hangzhou Grand Canal， is known as the three major projects in ancient China， which is the largest underground water conservancy irrigation system in the world. This paper uses the rank correlation coefficient method to analyze the water quality change of Karez in Turpan from 2011 to 2020. The research shows that the water quality of Karez meets the Class Ⅱ standard of the "Environmental Quality Standard for Surface Water" （GB 3838—2002）， has not changed significantly， and meets the water requirements for agricultural production and people's living.

Keywords： Karez; water quality; rank correlation coefficient
