Climate change impact on water resources is uncertain. This article reviews water resources changes during the past 50 years in China, as well as the modelled results under different scenarios, to figure out a basic framework on the relationship between climate change, water resources and water resources management. China is a rapidly developing country with a large land area and diverse landscape and climate. Due to
limited water resources, China is facing water shortage. Studies have shown that climate change has a significant impact on China, especially in north, which faces severe water shortage.
