【摘要】 陡河水库纳入电厂热排水后,年均水温升高3℃左右。根据水温及等温线分布情况,将库区划分为增温区、弱增温区、自然水温区三个区域。通过一年的定点网箱监测,结果表明:自然水温区鱼类生长最好,其次为增温区,弱增温区最差。增温不仅改变了鱼类生长,而且鱼类血液及生理指标也发生了改变。更多还原

【Abstract】 The annual mean water temperature of Douhe reservoir increaced by about 3℃ after receiving electric power plant heat drain.Three areas including temperature-increasing area,weak temperature-increasing area and natural temperature area were divided according to water temperature and isotherm distribution.After one-year monitoring of fixed netcages,the results showed:natural temperature area was the best for fish growth,and temperature-increasing area was better for fish growth than weak temperature-increasing area.Temperature-increasing not only changed fish growth,but also blood and physiological indices of fish.更多还原
