Phytoplankton is a fundamental element for primary production and food chain in the reservoir environment, where its quantity and biomass values have shown significant influence on the environmental factors, which in further determines the biological balance of the reservoir water. Through the monitoring and investigation of the phytoplankton quantity and water environmental factors in Hedi reservoir by using SPSS 18.0 statistical software to perform variance analysis and correlation analysis of the phytoplankton quantity, biomass values and environmental factors, the results showed that the phytoplankton quantity and biomass in the reservoir had demonstrated significant difference (P < 0.05), where it was relatively large in the summer and smaller in the winter, which was influenced by the water temperature, except that sample No.1, 2 did not show much difference in the summer. Phytoplankton quantity and biomass showed positive correlations with the environmental factors including water temperature, pH, dissolved oxygen, chemical oxygen demand and total phosphorus, where there are extremely significant positive correlations with the water temperature and chemical oxygen demand (P < 0.01), and significant positive correlations with total phosphorus (P < 0.05). They showed negative correlations with factors such as transparency, total nitrogen, ammonia nitrogen and nitrate-nitrogen, in which there are significant negative correlations with the transparency and ammonia nitrogen (P < 0.05). Therefore, it is shown that it is identifies as the nitrogen pollution. Thus, it is of importance for sustaining the health of the ecosystem in Hedi reservoir where the excessive domestic and industrial wastewater discharge around the reservoir should be controlled. This research can provide references and bases for the scientific management and protection of water quality.
