YANG Zhi-feng, ZHAO Yan-wei, CUI Bao-shan, HU Ting-lan (State Key Laboratory of Water Environmental Simulation, Institute of Environmental Sciences, Beijing Normal University, Beijing 100875, China).  
The principle of ecocity-oriented water resources supply-demand balance analysis is put forward, and the integrity of water quality and quantity, harmoniousness of human being and nature, and the priority of ecological environment water demand are emphasized. Based on these mentioned above, the conceptual framework of ecocity-oriented water resources supply-demand balance analysis is established and the basic intension of the balance is addressed in detail. The study for actual proving with Guangzhou as example is conducted. Eco-environmental water demand influences supply-demand balance notably; Huadu district and central region are short of water of 91 and 486 million m3/month respectively in dry season of 2000; and under the basic control scheme, there will be water shortage of 1974 million m3/month, 4187 million m3/month and 7762 million m3/month for the whole city in dry season of 2005, 2010 and 2020 respectively. In order to ensure the supply-demand balance, the integrative intensifying scheme with pollution load control and water saving as leading measures should be implemented.
