Abstract: Water resources have been intensively influenced by global warming.More and more studies have been focused on the impact of climate change on water resources,which also have attracted the eyes of policy makers.The article briefly reviews the development of the studies in this field internationally and nationally,and summarizes the results of observed historical climate change facts in Yunnan Province.Then it proceeds to explore the impacts of climate change on stream flow,suspended sediment yield,glacier and extreme events (storms,flooding and droughts) based on the previous studies in Yunnan Province.The existing weakness and research gap have been identified in the article,which will be helpful to guide the future studies on water resource adaptation to climate change in Yunnan Province.
