The　scientific　classification　of　rural　settlements　types　and　the　formulation　of　realistic　revitalization　development　paths　are　essential　for　rural　revitalization.　Rural　settlements　show　obvious　life　cycle　characteristics　in　their　development　process,　and　it　is　necessary　to　formulate　differentiated　revitalization　paths　for　different　types　of　rural　settlements.　Therefore,　a　case　study　is　conducted　in　Ke　Town,　farming-pastoral　ecotone　of　Northern　China,　based　on　life　cycle　theory.　This　paper　evaluates　the　current　situation　of　rural　settlements　from　the　perspective　of　＂factors-functions＂.　Through　social　network　analysis,　the　connection　strength　and　degree　centrality　are　measured　for　rural　settlements,　and　classifies　them　into　five　types　accordingly.　And　we　introduce　the　life　cycle　theory　to　delineate　the　development　stages　of　different　types　of　rural　settlements.　Finally,　we　identify　the　advantageous　factors　of　rural　settlements　and　analyze　the　characteristics　of　inter-village　population　mobility　by　means　of　triangular　model　and　field　research.　We　use　this　as　a　guide　to　formulate　revitalization　paths　for　different　types　of　rural　settlements.　The　results　show　that　the　＂factors-functions＂　spatial　correlation　network　is　characterized　by　obvious　spatial　differences,　where　rural　settlements　show　weaker　connection　strength　and　higher　degree　centrality.　Analyzing　the　combination　of　connection　strength　and　degree　centrality,　rural　settlements　are　classified　into　five　types:　suburban　integration　(11.11　%),　characteristic　protection　(5.00　%),　agglomeration　and　upgrading　(16.11　%),　maintaining　status　quo　(26.67　%),　and　relocation　merge　(41.11　%).　Meanwhile,　rural　settlements　are　divided　into　four　stages:　growth,　maturity,　decline,　and　transformation.　We　focus　on　the　characteristics　of　different　types　of　rural　settlements　at　different　stages　and　propose　multiple　revitalization　paths.　It　can　effectively　solve　the　development　dilemma　of　rural　settlements　in　the　region　caused　by　differences　in　resource　endowment　and　ambiguous　functional　positioning.　This　paper　provides　theoretical　guidance　for　classifying　the　rural　settlements　types　and　formulating　rural　revitalization　paths　in　the　farming-pastoral　ecotone.
