Abstract: With the increasing extent of exploiting and using groundwater, a series of ecological geology problems occur in most areas. In order to ensure the sustainable utilization of groundwater, it is urgent to adopt new theories and methods to manage groundwater rationally. Based on the natural attribute, social-economical attribute and ecological attribute of groundwater, established on the prevailing function, this paper builds up a framework of secondary functional area division. The first division framework includes exploitation area, protection area and the reserve area, detailedly in the first division, it includes centralized drinking water area, distributed exploitation area, ecologically vulnerable area, sensitive geology disaster area, groundwater-raising area, unavailable exploitation area, reserve area and emergency water area. The eight areas are called the subclass. The paper clearly defines each grade and kind of groundwater functional area, as well as the technical evidence to divide the areas. At last, relied on the framework and the division standard built up in this time, a work is going on to divide the national territory. The functional division of groundwater is a totally new job, and it's the first time to divide the areas nationwide.

Key words: groundwater, functional division, division system, division basis, division results
