CHEN Xing;ZHAO Ming;ZHANG Jie. POTENTIAL IMPACT OF SOUTH TO NORTH WATER TRANSFERRING ON THE DROUGHT IN NORTHERN CHINA[J]. Advances in Earth Science, 2005, 20(8): 849-855.
By using surface water balance model and energy balance model, the sensitive simulation experiments were made to explore the potential climatic influences of south to north water transferring project in northern China. The simulation results gave some possible local changes of soil moisture, evaporation, temperature and precipitation under different climatic scenarios. Results show that the different amount of water transferring will bring about different climatic effects when the climate backgrounds and seasons are different, and related to seasonal variation of precipitation. For the northern China, input water from the project could change the local soil moisture and runoff, and cause decrease in temperature in summer half year and increase in temperature in winter half year. At the same time, the local precipitation and evaporation in summer half year will increase, and those will change a little bit in winter half year. Therefore, the central line project of south to north water transferring will not only resolve the problem of water resources shortage in north China, but also improve the local drought climate environment to some extent. It is beneficial for the regional ecological environmental positive circulating and sustainable development.
