Abstract

This paper introduces a simple method to assess aquatic environmental quality in water quality of a lake. Lake Dianchi was used as a case study. The sediments, contributing rivers, and water body of the lake are taken to represent the whole lake's aquatic environment. They are analyzed and ranked through PCA and relative principal component. The result showed that the worst and best sediment sampling points are Yunlianghe River and Guanyinshan West. Among all the 26 contributing rivers, Xinher River is ranking the first, representing the worst water quality. The Dongdahe River is ranking the last, representing the best water quality among all rivers. The yearly water quality ranking of Lake Dianchi is varied in different years. There isn't a fixed direction in water quality evolvement. It showed that water pollution control is a hard issue.
