Vegetation　indices　is　often　used　to　assess　vegetation　dynamics　and　conditions.　This　paper　presents　a　primary　analysis　of　MERIS-Full　Resolution　(FR)　data　to　observe　seasonal　variations　of　Normalized　Difference　Vegetation　Index　(NDVI)　in　Fujian　province,　Southeast　China.　The　standard　NDVI　of　MERIS　is　calculated　by　band　6　and　10.　We　found　that　the　results　were　better　when　the　red　band　6　replaced　by　another　red　band　8.　The　modified　NDVI　(MNDVI)　enhances　vegetation　feature　while　efficiently　suppressing　and　even　removing　bare　land　information.　Vegetation　in　summer　in　2004　had　a　inferior　condition　than　that　in　2005　according　to　combined　MNDVI.　Temporal　and　spatial　change　of　MNDVI　preferably　response　to　climate　change　in　the　study　area.　These　meteorological　variables　influence　MNDVI　variability　of　different　season.
