Abstract: Northwest China is lack of water resources and ecological environment is fragile.Owing to unreasonable development of water and land resources,many problems of ecological environment(such as land desertification,salinization,etc.)have occurred.The evolution law of groundwater system must be followed for improving ecological environment and reasonable exploitation and utilization of water resources.This thesis analyzes and compares the characteristics of the aquifer systems and groundwater runoff systems of the various large interior basins in Northwest China.The transformation modes of surface water and groundwater are identified using method of fuzzy mathematics.The result shows that the transformation modes are not only unanimous in form but also analogous in the proportion of transformed quantity.The impacts of hydrologic environment and human activity on groundwater cycle and evolution laws are discussed.Finally,the thesis gives some proposal about the rational exploitation and utilization of water resources in these basins.

Key words: hydrology and water resources, evolution law, modes identification, groundwater system
