Recently, global climate change has led to significant changes in the Qaidam Basin. Temperature and precipitation are two important indicators of climate change. Since the beginning of the 21st century, the times of heavy rain and rainstorm disaster in summer have drastically changed in the Qaidam Basin due to the driving factors of climate change and human activities. To further understand the summer rainstorm disaster and its influence on the Basin, linear regression, correlation, and smooth average analysis were performed based on ten meteorological stations from 1961 to 2018 to analyze the spatial and temporal characteristics of heavy rainfall. This paper analyzed heavy rainfall variation and its days from 1961 to 2018 in the Qaidam Basin, the risk zoning of rainstorm disaster, and its influence on industries. The results indicated: (1) a recent increasing trend of precipitation and heavy rainfall periods in summer (for the past 58 years) in the Qaidam Basin (7.5 mm and 2 times higher every decade, respectively), and a recent increasing trend of heavy rainfall periods (for the past decade) averaging 17 times, which was 6 times higher than the period from 1981 to 2010. Also, in the mid-eastern Qaidam Basin, there was a significant increase in heavy rainfall. (2) an increasing trend of rainstorm disasters from 1990 to 2018; the rate was 2.5 times higher every decade, especially in Dulan, Ulan, Tianjun, and Delingha since the 21st century, which also increased the risk of disaster. (3) the hazard factor and hazard-bearing body in Tianjun county, which belonged to the highest risk region, and Dulan, Ulan, and Delingha county, which belonged to the higher risk regions. Assessments of industries were accordingly conducted. The regionalization results agreed with the flood history records in the Qaidam Basin. Following the results, this study provided some references for the relevant government departments and insurance and agricultural production industries to help reduce rainstorm disaster losses.
