In　this　paper,　MODIS　normal　difference　vegetation　index　(MODIS　NDVI)　products　of　Huang-Huai-Hai　Plain　in　2001,　2005,　2010,　2015,　and　2018　are　used　as　data　sources.　With　the　help　of　MRT,　ENVI,　ArcGIS,　and　Excel　software　operating　platforms,　at　the　same　time,　using　maximum　value　composites　method,　mean　method,　unary　linear　regression　method,　and　trend　analysis　method　to　generate　the　time　series　data　of　monthly,　seasonal,　and　annual　NDVI,　which　is　to　study　and　analyze　the　spatial　and　temporal　change　characteristics　and　laws　of　vegetation　in　Huang-Huai-Hai　Plain.　The　results　show　that　in　the　past　18 years,　the　average　annual　NDVI　has　shown　a　downward　trend.　On　the　time　scale,　the　NDVI　has　obvious　seasonal　and　interannual　variations　with　growing　fastest　in　summer　and　the　maximum　occurring　in　July,　while　the　growth　rate　in　spring　and　autumn　is　relatively　flat　and　the　minimum　occurring　in　December.　On　the　spatial　scale,　the　NDVI　has　fewer　growth　regions　that　are　mainly　distributed　in　the　central　and　western　regions,　while　the　regions　where　NDVI　declines　are　relatively　more　and　mainly　distributed　in　the　northern　and　southern.　©　Springer　Nature　Singapore　Pte　Ltd　2020.
