Title
A Correlation between the Algal Growth and Water Quality Factors Depended on Algae Growth Stages in Lake Juam
이태관 Tae Gwan Lee
Abstract
In common case, the algal growth curve is divided into 4 stages such as a lag phase, a log phase, a stationary or death phase. The algae needs several different nutrients at each phase. In this study, I tried to analyze a correlation between a algal growth divided on algae growth stages and water quality factors in lake Juam. On the result of analysis, there was a normal correlation between Chl-a and several factors and conductivity on the lag phase. On the log phase, strong correlations began to show between Chl-a, the number of cyanobacteria and water quality factors affiliated with phosphorus element. And the number of cyanobacteria also began to relate high to the number of green and total algae. During an entire period, there was a significant correlation between Chl-a, nitrogen and phosphorus, so nutritive salts had a possibility to be a major nutrient for a algal growth. To control a algal growth for lake Juam, I recommend to make the basic plan of water quality management included nutritive salts control plan for the entire period.
