摘要：

Energy budget of the water body of the Nanhu lake in Changchun city was studied at ecosystem level.The water surface received 4969635.4kJ·m -2 radiant energy annually,which was used to conduct the physical and biological reactions in the lake,as well as the energy exchanges with surroundings.Loss by evaporation amounted to 55 9% of the total radiant energy received by the lake body,with reflection 17 8%,exchange with atmosphere 14 0%,increase of water temperature 6 6%,ice melting 4 9%,primary production 0 6%,and exchange with bottom 0 2%.Finally, the energy budget of the Nanhu Lake was compared with other water bodies.
