The effect of physicochemical factors on the population of phytoplankton and the quality of Bijar surface water

As the most valuable and most important organisms in aquatic ecosystems are Phytoplankton that have important role in the river water quality. Quality and quantity of phytoplankton depend in part on load of water nutritious. Therefore, the use of phytoplankton in different ecosystems, water is used to measure water quality or pollution of water. The river Gilan Bijar in the area the main rivers in the country In addition to the main source of drinking water for different uses in agriculture and the economy area is important. In this study, the impact physicochemical factors on the composition and frequency of phytoplankton in different seasons were analyzed. The results of the study of biological River Bijar indicates the presence of 5 branches and 57 Genus the region. The frequency of Bascillariophyta branches on other branches was dominant in all seasons. Data collected for all the parameters are normally distributed ،was determined using the Kolmogorov-Smirnov test. The correlation between phytoplankton and physicochemical parameters shows. The number of phytoplankton significant correlation with the parameters of temperature and PH and nitrogen. It also uses GIS software and takes advantage of various colors, color zoning qualitative phytoplankton was prepared
