The impact of climate variation on water resources is one of the current hot and frontier issues of global change study. The research on impact of climate variation on water resources in arid inland river basin is paid more and more concern and attention by many scholars..This paper reviewed the current research situation and progress of influence of climate change on water recourses and summarized relative research methods. It summaried the relative research results from 4 aspects such as hydrological elements, quantitative assessment of climate and human activities for water resource, the influence of climate change on extreme hydrological events and the adaptive management countermeasures of water resource to deal with climate change.This paper outlined both the problem and the future development trend of the influence of climate change on water resources in arid region of inland river basin.
