Abstract
The sustainable development of the Yangtze River will affect the lives of the people who live along it as well as the development of cities beside it. This study investigated the relationship between shipping development and the water environment of the Yangtze River. Canonical correlation analysis is a multivariate statistical method used to study the correlation between two groups of variables; this study employed it to analyze data relevant to shipping and the water environment of the Yangtze River from 2006 to 2016. Furthermore, the Yangtze River Shipping Prosperity Index and Yangtze River mainline freight volume were used to characterize the development of Yangtze River shipping. The water environment of the Yangtze River is characterized by wastewater discharge, ammonia nitrogen concentration, biochemical oxygen demand, the potassium permanganate index, and petroleum pollution. The results showed that a significant correlation exists between Yangtze River shipping and the river’s water environment. Furthermore, mainline freight volume has a significant impact on the quantity of wastewater discharged and petroleum pollution in the water environment.

Summary
The sustainable development of the Yangtze River is crucial for the lives of the people and the development of the cities along it [1,2]. Water pollution in the Yangtze River will indirectly affect the economic situation of the cities in the basin [9]. Research on the pollution in the Yangtze River water environment is mainly focused on the effects of heavy metal, waste dumping, organic micropollutants, and dam construction [11,12,13,14,15]. The impact of waste dumping on the water environment of the Yangtze River was determined with statistical data and spatial patterns, and the subsequent environmental impact on local and water ecosystems was evaluated [13]. Canonical correlation analysis (CCA) is employed to determine the relationship between shipping and related water environment in the Yangtze river.
