摘要

针对湖泊热环境容量小，生态系统脆弱的特征，以三峡库区重庆段湖泊水体为研究对象。采用物理模拟的方法，对湖水源热泵系统冷排水对湖泊藻类及叶绿素含量的影响进行了系统的研究。结果表明：冷排水对藻类总量增长有明显抑制作用，试验水体藻类正负增长的临界温度在4.5～6.2 ℃之间；冷排水对湖泊优势藻类种群及比例变化有较为明显的影响，并且会使藻类种群数减少；冷排水显著降低湖泊叶绿素a的含量，对浮游植物总量增长有较大影响，且原水氮磷含量越高其影响程度也越大。

Abstract

According to small environmental capacity and fragile ecosystem of lake

the lakes in Chongqing Section of Three Gorges Reservoir Region were taken as a case. The effects of cold water discharge of lake water source heat pump systems on lake algae and Chla were studied with the method of physical simulation. It was found that cold discharge discouraged the growth of algae

and the critical temperature of algae growth was between 4.5℃ and 6.2℃. There was significant impact of cold discharge on dominant populations and its proportional change of algae. And it would reduce the number of algal populations and the content of Chla. Furthermore

the cold discharge would have great influence on total quantity of phytoplankton. And the higher the content of nitrogen and phosphorus of raw water was

the greater of the effect extent was.
