The Hutuo River is located in the semi-arid areas in China. Due to lack of water resources in these areas, changes in flow regime, mainly reduction in runoff downstream from the reservoirs, have been tremendous. As a result of decrease in flow power

L'A. présente un modèle de l'offre et de la demande d'eau à l'horizon 2030 et à l'échelle de la plaine chinoise du nord. Le modèle prévoit des contraintes sévères de 1993 à 2000. Il envisage que les besoins nécessités par le développement socio
-économique et l'environnement ne seront pas satisfaits entre 2000 et 2030. La mise en oeuvre du projet de transfert d'écoulement du sud vers le nord est la seule solution susceptible de résoudre la crise de l'eau.
Aiming for a high-resolution Quaternary history for southeastern China, this paper documents palynological details and uses the synthesized data, as well as those for diatoms and foraminifera, to interpret local sea-level and climatic changes
