By using experimental ecological methods, the 24 hours semi-lethal temperature (24 h LT50) of typical copepods living in the coastal area of East China Sea was determined to elucidate the effects of thermal discharge from power station on the coastal ecosystem. The results indicated that different copepods at same natural acclimated temperature and specific copepod at different initial acclimated temperature had different thermal tolerance capability. The 24h LT50 of Calanus sinicus and Sinocalanus tenellus at natural acclimated temperature 13.5 degrees C was 26.9 degrees C and 25.4 degrees C, of Acartiella sinensis and Corycaeus affinis at natural acclimated temperature 14.2 degrees C was 26.7 degrees C and 30.5 degrees C, and of Centropages dorsispinatus, Paracalanus crassirostris, Acartia spinicauda and Euterpina acutifrons at natural acclimated temperature 28.0 degrees C was 34.0 degrees C, 34.3 degrees C, 35.7 degrees C and 36.0 degrees C, respectively. The 24h LT50 of S. tenellus at natural acclimated temperature 13.5 degrees C and 23.5 degrees C was 25.4 degrees C and 33.0 degrees C, respectively.
通过采用实验生态学方法，测定了生活在东海沿岸海域典型桡足类的24小时半致死温度（24 h LT50），以阐明电站热排放对沿岸生态系统的影响。结果表明，在相同自然驯化温度下不同的桡足类以及在不同初始驯化温度下特定的桡足类具有不同的热耐受能力。中华哲水蚤和瘦尾胸刺水蚤在自然驯化温度13.5℃时的24 h LT50分别为26.9℃和25.4℃，中华小哲水蚤和近缘真刺水蚤在自然驯化温度14.2℃时的24 h LT50分别为26.7℃和30.5℃，背针胸刺水蚤、粗壮伪镖水蚤、刺尾纺锤水蚤和尖额真猛水蚤在自然驯化温度28.0℃时的24 h LT50分别为34.0℃、34.3℃、35.7℃和36.0℃。瘦尾胸刺水蚤在自然驯化温度13.5℃和23.5℃时的24 h LT50分别为25.4℃和33.0℃。
