Heat balance of urban ecosystem is a key point for the study of urban climate and micro- climate pat- tern and its change mechanism�� Urban heat island effect is becoming increasingly serious��which is mainly caused by the change of the earth's surface cover and the anthropogenic heat release�� In this study��the simula- tion experiment for the anthropogenic heat release was designed according to the heat balance principle�� A set of buildings of miniature city were used to constitute the residential area��U grooves were applied to simulate the single building��and the fluorescent lamps in the U groove were regarded as the heat sources of the anthropoge- nic heat release�� The simulation experiment was launched with long- short wave sun photometer��sonic anemo- thermometer and heat flow gauge in the experiment site�� Then the net solar radiation��sensible heat flux and heat flux into the ground were determined�� The quantities of the anthropogenic heat release were calculated based on the heat balance principle��and were compared with the theoretical power consumption of the fluores- cent lamps�� The root mean square error (��MSE) of the simulation for the anthropogenic heat release reaches 0.078 W ·m^-2 ��a comparatively high precision��which showes that the anthropogenic heat release can be accu- rately determined through the simulation experiments�� This study provided a scientific method for the purpose of monitoring the anthropogenic heat release��
