摘　　要：本文应用能量平衡方程(QSR-R-LE-H-ES-EA-PS=0),对三江平原池塘生态系统的热量平衡进行了研究和分析。发现在三江平原池塘生态系统热量平衡中,由于水体增温所消耗的能量为28470.2kJ/m^2,大约为这个阶段水面接受太阳辐射的2.2％;池塘水体与池塘底部土壤的热量交换为52251.3kJ/m^2;池塘水体蒸发耗热量为921933.4kJ/m^2;池塘水面反射的太阳为147210.7kJ/m^2;浮游植物光合作用所消耗的能量为5417.8kJ/m^2;由池塘水体通过辐射、对流和传导与大气进行热量交换损耗的能量为565584.8kJ/m^2。The research and analysis had been carried out on heat budget of the pond ecosystem in Sanjiang Plain with the equation of energy balance (QSR-R-LE-H-ES-EA-PS=0). It is found that in the experiment time, the energy lost through rising of water temperature is 28470.2 kJ/m^2, which makes up 2.2% of total solar and sky radiation received by the surface of the pond in Sanjiang Plain. The energy exchange between water and the bottom of the pond was about 52251.3kJ/m^2, The energy lost by water evaporation was 921933.4kJ/m^2, and the radiation reflected by the surface was about 147270.7kJ/m^2. The albedo was 8.5%. The energy used by phytoplankton in photosynthesis process was about 5417.8kJ/m^2. The energy lost through exchange between water and air was about 565584.8kJ/m2. The solar and sky radiation received by the surface of the pond was 1729047.9kJ/m^2.
