摘　　要：利用9口滨海型盐碱地型池塘,以乌克兰鳞鲤(Cyprinus carpio)为主养鱼,研究了不同放养密度(400、600、800尾/亩)下池塘能量生态学的变化。结果表明:三个密度组池塘水体光合作用效率差异显著,800尾/亩组显著高于400尾/亩组(P<0.05);在各输入能的转换效率中,光合能毛产转换效率和净产转换效率、鱼种能毛产转换效率和净产转换效率差异显著(P<0.05),800尾/亩组的光合能毛产转换效率和净产转换效率显著高于600尾/亩组,鱼种能毛产转换效率和净产转换效率都显著低于400尾/亩组;三个密度组的综合性生态-经济指标EY值依次为0.65、0.67、0.76,800尾/亩组的综合效益最高。The energy ecology of 9 ponds of saline-alkaline land for Ukraine scale carp（Cyprinus carpio） culture,with densities of 400,600,800 ind per 667 m2,was studied.The results showed that there were significant differences on photosynthetic efficiencies,and the photosynthetic efficiency in group of 800 ind per 667 m2 was higher than that in group of 400 ind per 667 m2（P0.05）.In all input energy conversion efficiencies,there were significant differences on gross photosynthetic energy conversion efficiencies,net photosynthetic energy conversion efficiencies,gross fry energy conversion efficiencies and net fry energy conversion efficiencies.The gross and net photosynthetic energy conversion efficiencies in group of 800 ind per 667 m2 were higher than that in group of 600 ind per 667 m2,and the gross and net fry energy conversion efficiencies in group of 800 ind per 667 m2 were lower than that in group of 400 ind per 667 m2.The comprehensive ecology-yield index values in the three groups were 0.65,0.67 and 0.76 respectively,which showed that the group of 800 ind per 667 m2 was the best among the three groups.
