Abstract

This paper studied the relationship of chlorophyll-a, total nitrogen (TN) and total phosphorus (TP) concentration based on the conventional monitoring data in 2013. The results showed that the concentration of chlorophyll-a (Chl.a) had obvious correlation with TN, TP in July and August, and there was no relationship in October. Furthermore, content of nitrogen is more relevant to chlorophyll-a than phosphorus by regression analysis. Therefore, it was indicated that nitrogen and phosphorus nutrients had intimated relationships with algae growth.
