Abstract: Climate change can impact water environment quality in many ways, and the recognition of its impact mechanism is a research hot-point and frontier. By studying the related scientific and technical literatures, this paper systematically summarized the research progress in the total impact of climate change on water quality in plateau cold region, evolution mechanism and numerical simulation of water quantity and water quality in plateau cold region, water quantity and water quality evolution law of Nam Co Lake in Tibet etc. On this basis, the urgent scientific research issues and the main research contents for impact mechanism of climate change on water quality in plateau cold region were further discussed．

Key words: climate change, water quality impact, impact mechanism, plateau cold region
