Abstract:: This article analyzes the trends of human activities and climate change for many years from the view of Shiyang River Basin groundwater circulation. Using the principal component regression analysis to analyze the effect and get the contribution rate of climatic change and human activites on groundwater in Minqin Basin. The results show the average annual temperature and the average rainfall for many years have a slight increase.The average evaporation increased in volatility. Human activities are changing the groundwater-row conditions through expanding irrigated area, improving the canal system lining and exploiting groundwater.The anthropogenic factor plays a leading role in groundwater resources variation in recent 50 years, and its effect accounts for 79.12% of the total effect. Under climatic change and human activies, the groundwater table is increasing, and the ecological environment is worsening.
