【Abstract】 This paper presents a new concept of background value in given time interval(BVTI) and offers a method for groundwater quality integrative evaluation based on BVTI.This method provides a new effective tool to exploit and manage groundwater rationally further because it possesses the characteristic of macro-assessing and regulating groundwater.Meanwhile,it is helpful to probe into the evolution history of groundwater quality from different perspectives and to reveal the groundwater pollution essence roundly in quantification by using the new concept and method.更多还原
