英文摘要：

In this paper, the theory on assessment of regional groundwater function is introduced. The present work aims at the integrated utilization of groundwater resource function, ecological function and geological environment function, focuses on the natural attributes of a groundwater system. With the regional water cycle theory, systematology and the analytic hierarchy process method （AHP）, the primary concepts and the methodology of groundwater function assessment are developed in this paper, including the rule, criteria, mathematic methods and indicator systems. A case study is carried out in the Hutuohe River Basin as the representative area of the North China Plain, in which the connotation of groundwater function and the regionalization method were improved and enriched. In the built theory the groundwater assessment was carried out with too much emphasis on its resource attributes and its ecological and geological environment function in North China was neglected, leading to many environmental problems in the past decades.
