摘要：The 12th international symposium on Advances in Isotope Hydrology and its Role in Sustainable Water Resources Management (IHS–2007) was held in Vienna, from 21 to 25 May 2007. The symposium was divided into an opening session, a series of nine invited lectures, a series of eight case study lectures, three poster sessions (at which 135 posters were presented), a scientific side visit, two roundtable discussions, technology demonstrations, and a closing session. The poster sessions were very well attended and generated substantial interactions among participants. Technical presentations were organized through a series of themes which are described below. There were 213 registered participants, 14 observers, and 6 exhibitors. Participants came from 59 Member States, and 32 grants were provided to participants from developing countries. Four new aspects of this symposium were the focus on poster sessions over oral presentations, the scientific side visit, the roundtable discussions, and the technology demonstrations.
