Abstract	Several anthropogenic heat release models are tested in a regional atmospheric boundary layer model, the results demostrate that the diurnal variations of antrhropogenic heat release must been taken account in the model. The contribution of anthropogenic heat on local urban micro-climate and boundary layer structure is also analyzed based on the numerical simulations over Hangzhou city, Zhejiang province, China. The results show that: the contribution of anthropogenic heat to urban heat island intensity is greatest in the evening and at night and least in midday time, the daily averaged is 43.6%. The anthropogenic heat release leads to a reduce of wind speed at low atmospheric layer and may strengthen urban heat island circulations. It also strenghten turblence in urban boundary layer, cause a mor unstable atmospheric boundary layer, especially in the morning and evening.
