Abstract

This research aimed to study the diversity of phytoplankton in standing water resources distributed in the Mae Ram basin area, Mae Rim District, Chiang Mai Province, as well as to assess the water quality by using phytoplankton. Thirty water samples were collected from 10 sites from June to December 2019. Most of the water resources had moderate, and moderate to polluted water quality. They could be utilized for consumption by regular disinfection and general water treatment process, and also for agricultural purposes. The water resources were grouped by Cluster Analysis. It was found that at the level of similarity of 70%, the water resources were divided into four groups. The phytoplankton was found a total of 6 divisions, 39 genera, 65 species. The most dominant species is Trachelomonas volvocinopsis Svirenko, followed by Cosmarium askeasy Schmidle and Chlamydomonas gloeopara Rodhe & Skuja. When analyzed the relation of phytoplankton and water quality parameters using Pearson's Correlation, it was found that Actinastrum sp., Ch. gloeopara Rodhe & Skuja, and C. askeasyi Schmidle were positively correlated at a high level with TDS values. This indicated that this group of phytoplankton had the potential to be used as bioindicators.
