This article takes the third drainage ditch in Ningxia as the research object, and uses the multivariate statistics method to analyze the interrelationship between the four major pollutants at nine regional points in the main pollution ditch section of the third drainage ditch throughout the year from the perspective of time and space, to improve the water environment quality. SPSS (Social Statistics Software Package) is used to analyze chemical oxygen demand, total phosphorus, total nitrogen, ammonia nitrogen, and index of major pollutants of permanganate. The research results show that the main pollutants and the degree of pollution affecting the water quality of the third drainage ditch are: total nitrogen> ammonia nitrogen> total phosphorus> chemical oxygen demand. At the end of San’er, ammonia nitrogen and total nitrogen were the most polluted. At the Dawukou section of San’er, the chemical oxygen demand and total phosphorus were the heaviest.
