Fl uorine in aquatic environment in the western region of Songnen Pla in ( ) WAN G Wenj un ,ZHAN G Xuelin 　Changchun Institute of Geograp hy ,Chinese Academy of Sciences ,Changchun 13002 1 Abstract 　In t he western region of Songnen Plain ,t he dist ribution of fluorine in aquatic environment is t hat t he fluorine content in lake water and unconfined water is higher t han t hat in river water and confined water . Lake water ( salt lake) is cont rolled and supplied by underground water . The isogram of t he fluorine content in underground water in t he western plain of Jilin Province shows t hat t he fluorine content alter nates wit h high and low fluorine content in unconfined water . The t hreedimensional diagram of t he fluo rine content shows t hat t he t rend of t he fluorine content dist ribution is t hat it gradually decreases from east and sout heast to west and nort hwest in t he western region of t he Songnen Plain . The fluorine in water comes from t he weat hering of rocks and minerals in t he mount ains around t he Songnen Plain . Under t he influences of natural landscape difference ,local climate ,hydrochemist
