Impact Analysis of Climate Change on Water Resources

AbstractIt has theoretical and realistic meanings to study the climate change's impacts on hydrology and water resources, so as to understand and solve some problems in hydrology and water resources, such as plan management, operation management, environmental protection, ecological balance and so on. And hydrology and water resource system has close relationship with industry, agriculture, city development and economic fields. This paper reviews the relationship between climate change and water resources, water circulating response of climate change. And then summarizes some study methods of analyzing the impacts of climate change on hydrology and water resources, such as generation technology for climate change scenario and hydrologic simulation. At last, it raises problems in study and puts forward the development trend, including perfecting the distributed hydrological model, improving the precision of climate models and hydrologic models and developing the two-way coupling techniques of climate models and hydrological models
