| 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308kJ.m-2,动物性能量86kJ.m-2);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。

| Abstract: | Through sampling in field and analysis in lab,obvious vertical distribution of biotic energy in the Nanhu Lake waterbody of Changchun 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 monitoring,fishery production and bloom control. |
