| 摘 要： | 1996年4月至1997年3月对典型草型湖泊－－扁担塘大型底栖动物群落的能量流动及特性进行了研究，结果表明，扁担塘大型底栖动物群落的总摄食能为2119.5kJ.m^-2.a^-1，代谢能为389．7kJ.m^-2.a^-1，排粪能为1642．1kJ.m^-2.a^-2，排泄能为34．6kJ.m^-2.a^-1，生长能（生产量）为53．1kJ.m^-2.a^-1；群落的平均同化效率为22．5％，表明77．5％的摄食能被排泄掉；净生长效率为11．8％，明在中营养水平的水环境中该群落对食物的利用效率极低。

| Abstract: | Energy flow of the macrozoobenthic community mainly composed of chironomids, ga stropods and oligichaetes in a macrophytic lake, Biandantang Lake (Hubei, China) was investigated by a combination of field and laboratory data from April, 1996 to March, 1997. The estimated consumption of the community was 2119.5 kJ·m -2·a -1; defecation was 1642.1 kJ·m -2·a -1; respiration 3 89.7 kJ·m -2·a -1; excretion 34.6 kJ·m -2·a -1 and pro duction 53.1 kJ·m -2·a -2. The assimilation efficiency of the commu... |
