Under　the　background　of　territorial　spatial　planning　in　the　new　period,　delimiting　the　urban　development　boundary　scientifically　and　reasonably　and　establishing　a　sound　territorial　space　use　control　system　are　important　measures　to　guide　all　kinds　of　territorial　space　development　and　protection.　Taking　Fuzhou　City　as　an　example,　this　paper　constructs　a　global　multi-dimensional　territorial　space　control　system.　Management　and　control　constraints　are　embedded　in　the　future　land　use　pattern　simulation.　At　the　same　time,　considering　the　regional　spatial　heterogeneity　and　spatial-temporal　dependence,　this　paper　designs　the　Spatial-temporal　Cellular　Automata　(ST-CA)　model　which　integrates　geographical　partition　strategy,　deep　learning　technology,　and　the　functional　module　of　FLUS　model　to　delimit　the　urban　development　boundary.　Based　on　the　existing　achievements,　this　study　integrates　three　zones　and　three　lines　to　carry　out　the　application　research　of　spatial　management　and　control　under　the　thinking　of　＇combination　of　planning　and　control＇.　The　results　show　that:　(1)　The　ST-CA　model　considering　regional　spatial　heterogeneity　and　spatial-temporal　dependence　can　effectively　improve　the　accuracy　of　land　use　change　simulation　and　achieve　a　more　realistic　and　accurate　geographical　simulation　process.　The　overall　accuracy　of　the　model　increased　from　95.95%　to　98.34%;　(2)　Control　constraints　are　embedded　in　the　process　of　geographical　simulation,　which　can　guide　the　rational　layout　and　controllable　scale　of　urban,　agricultural,　and　ecological　spaces.　Delimitation　of　urban　development　boundary　based　on　simulation　results　can　effectively　avoid　occupation　on　protected　land;　(3)　The　future　simulation　results　combined　with　the　control　early　warning　value　show　that　the　urban　expansion　situation　in　the　main　urban　area　and　surrounding　districts　and　counties　of　Fuzhou　City　is　relatively　severe.　In　the　future,　it　is　urgent　to　reasonably　regulate　the　territorial　space　pattern　of　Fuzhou　City;　(4)　The　characteristics　of　boundary　change　trend　show　that　the　delimitation　results　are　consistent　with　the　long-term　development　planning　of　Fuzhou　City,　which　is　in　line　with　regional　development　demands.　The　territorial　space　pattern　presents　a　multi-axis　development　trend.　The　research　results　can　provide　scientific　planning　for　the　development　and　protection　of　territorial　space　and　practical　reference　for　territorial　space　control　and　optimization　in　Fuzhou　City.　©　2022,　Science　Press.　All　right　reserved.
