中国黄河の流域水資源管理の課題

抄録

The shortage of water is emerging as a serious threat to the sustainable development in the North China due to its adverse economic and environmental impacts. Focusing on the Yellow River basin, this paper evaluates the past meteorological data related to climate change, and discusses their implications for water supplyand- demand balance of the region. Firstly, the temperature and precipitation data during 1951-1997 are analyzed. Then, the Yellow River basin is classified into six areas according to the indices derived from the temperature and precipitation data, and the relationship between agricultural water consumption and climate changes is discussed. Finally, an evaluation model about water supply-and-demand balance is proposed.
