With　the　rapid　development　of　digital　graphic　recognition　technology,　in　recent　years,　more　attention　is　given　to　the　subject　of　animal　and　plant　species　identification　which　has　become　a　popular　researching　field.　The　article　mainly　discusses　about　the　method　to　apply　graphic　analyzing　technology　for　bird　identification　research　in　the　case　of　acquatic　bird　protection　in　the　marsh　of　Minjiang　River　estuary.　It　also　put　forward　a　set　of　classification　case　with　SVM　Decision　Tree　for　protesting　information　through　deep　analysis　and　study　on　bird　color　graph　[2]　in　terms　of　shape,　color　and　texture.　The　case　takes　on　many　advantages　such　as,　excellent　classification　capacity,　firm　Over-generalization　and　accurate　classification,　which　help　to　solve　the　disturbing　classification　problem　lasting　for　many　years.　Moreover,　the　appearance　of　the　case　contributes　to　the　effective　recognition　and　classification　of　15　birds　species　in　Minjiang　River　estuary　wetland.　©　2011　Published　by　Elsevier　Ltd.
