Abstract This paper proposes the definition of groundwater environment evolution pattern by researching the evolution law of groundwater environment in Yishu Basin, and divides the groundwater environment evolution into five patterns according to the different influence degrees of climate change and human activities. According to the groundwater dynamic monitoring data of the study area from 1980 to 2014, the quantity and quality changes of the groundwater system in Yishu Basin under the influence of climate change and human factors were analyzed, and the groundwater environment evolution pattern was identified. The results showed that the groundwater environment evolution in the study area was mainly affected by climate change before the 1980s, and it was represented by evolution pattern II, the range of evolution pattern I was very small. Since the 1990s, the influence degree of human activities had gradually increased, and the range of evolution pattern III and pattern IV had gradually increased. There had not yet appeared evolution pattern V. The research on the groundwater environment evolution pattern in the study area can scientifically program the groundwater use mode, coordinate the relationship between society and nature, and provide a scientific basis for the area as an emergency water source in Changchun and Jilin.

The groundwater environment is a unified body of continuous development and evolution. Under the joint influence of climatic conditions, topography, geological structure, land use type and human activity intensity, the groundwater environment evolution shows obvious differences. In recent years, with the acceleration of the socialization process, human activities have gradually destroyed the law of groundwater circulation evolution under natural conditions. In some areas, even the phenomenon of groundwater system function decline and imbalance has appeared. Therefore, mastering the evolution characteristics and genetic model of groundwater environment in a region is of great significance for improving the groundwater environment in the region. Beginning in the 1950s, UNESCO launched the International Hydrological Programme, whic
