湖水源热泵系统对水体浮游藻类的影响分析

The community of planktonic algae and the space-time differentiation of algae density are stated based on surface water heat pump system in Chongqing in the present study. The results showed that the minimum and maximum population of algae occurred in January and August respectively, and the population of algae increased gradualy with the distance between sampling spots and the outfall increased in horizontal direction. Moreover, the difference of algae species in summer is greater than in winter. From the analysis of the dominance degree of algae species, we can draw a conclusion that the dominant species changed for seasonal succession obviously. In addition, we got the regression equation of algae density through the fitting of algae density and water temperature .
