- 摘要：研究表明,热污染对水环境影响主要表现在水温的频繁变化、水平和纵向上温差明显以及改变水生物的群落结构.寄生虫感染率增加,冷热冲击对胚胎发育的危害和浮游生物群落变化形成的饵料基础是影响鱼类数量和生长的重要因素,鱼类在群落中的生态位特点则决定着对各种变化的反应结果.
- Abstract：Effects of thermal pollution on aquatic environment and abundances of five fish species by were analyzed. Frequent change in water temperature, temperature variations in both horizontal and vertical directions and the variation in aquatic community structure were observed. The main reasons for causing the changes in fish abundance and growth rate were found to be the increase in parasite infection rate, the endangerment of the cool-heat shock on fish embryo and the change in food value.
- Key words：thermal pollution temperature fish niche
