The　realization　of　distributed　geographic　information　access　is　only　the　first　step　to　construct　＇Digital　Province＇　and　＇Digital　City＇.　Only　the　shared　geographic　information　is　represented　properly,　can　it　be　understood　and　used　widely.　In　this　paper,　taking　into　account　the　practical　demand　of　distributed　geographic　information　sharing　in　the　construction　of　＇Digital　Province＇,　we　put　forward　the　distributed　geographic　information　representation　theory　and　technology　that　is　based　on　the　symbol　library,　template　library　and　knowledge　library.　In　the　realization　technology　system　the　core　technology　is　the　XML-based　geographic　information　representation　technology.　So　we　also　introduce　the　XML-based　geographic　information　representation　principle　in　detail.　The　implementation　technology　of　web-based　symbol　library　is　also　introduced.　At　last　we　introduce　the　application　of　our　theory　in　the　construction　of　＇Digital　Province＇　of　China,　which　has　validated　the　feasibility　of　our　research.
