Due　to　the　rapid　growth　in　the　number　and　size　of　intensive　animal　industries　in　China,　the　resulting　decline　in　air,　soil　and　water　quality　has　necessitated　the　development　of　sustainable　animal　production　management　strategies.　The　most　important　criterion　for　sustainable　animal　production　is　the　selection　of　appropriate　land　areas,　which　meet　several　biophysical,　environmental　and　socio-economic　restrictions.　Geographic　Information　System　(GIS)　that　is　capable　of　processing　large　volumes　of　spatial　data　can　be　a　useful　tool　to　offer　site　suitability　analysis.　This　paper　describes　the　development　of　using　raster　GIS　to　delineate　optimal　land　areas　for　locating　pig　production　farms.　Raster　GIS　can　produce　a　suitability　map　that　considers　the　land　use,　soil　type,　slope,　proximity　to　roads　and　surface　water,　and　other　site　selection　regulation　for　animal　production　farms.　Results　obtained　from　the　study　showed　that　the　suitability　map　can　be　a　useful　site　selection　guide　for　animal　production　farms　and　a　scientific　support　to　development　of　sustainable　farm　management　strategies　for　decision-makers,　farmers,　and　resource　managers.　©　2008　IEEE.
