中文摘要：
通过野外采样和室内分析，发现长春南湖水体的生物能量具有明显的垂直分层。生物能量在水下0～1．5m层最为集中，达394kj·m^-2（包括植物性能量30810·m^-2，动物性能量86kJ·m12）；其次是水上层（150kJ·m^-2）和底质层（144kJ·m^-2）；水面层（51kJ·m^-2）和水下1．5～3．0m层（45kJ·m^-2）的生物能量相近。水体生物能量的垂直分布可为水质监测、渔业生产和水华控制提供依据。
英文摘要：
Through sampling in field and analysis in lab, obvious vertical distribution of biotic energy in the Nanhu Lake waterbody of Changchtm was found. Biotic energy distributes most densely in 0 - 1.5 m underwater layer, which is 394 kJ· m^-2 （ including plant energy 308 kJ· m^-2, animal energy 86 kJ· m^-2）. Biotic energies in abovewater layer and sediment layer are 150 kJ·m^-2 and 144 kJ·m^-2 respectively. Biotic energy is similar on water surface （51 kJ·m^-2） and in 1.5 - 3.0m underwater layer （45 kJ· m^-2）. The vertical distribution of biotic energy in waterbody may provide basis for water quality monitoting, fishery production and bloom control.
