The　development　concept　of　＂Ecological　Life　Community　of　Mountains,　Rivers,　Forests,　Fields,　Lakes,　and　Grass＂　for　ecological　civilization　construction　holds　substantial　practical　significance　for　the　balanced　advancement　of　regional　economy,　social　development,　and　ecological　environment.　Constructing　an　ecological　security　pattern　(ESP),　a　significant　strategic　initiative　for　ecological　civilization-building,　is　essential　to　balance　protection　and　development　and　explore　a　harmonious　coexistence　between　humans　and　nature.　However,　traditional　research　methods　have　limitations　using　overly　simplistic　indicators　and　the　overlay　analysis　method　in　identifying　ecological　sources,　in　their　ability　to　discern　the　original　information　contained　in　various　factors　and　can　only　identify　homogenous　ecological　sources.　Accordingly,　taking　the　Poyang　Lake　Ecological　Urban　Agglomeration　(PLEUA)　as　an　example,　this　study　constructs　an　innovative　framework　for　regional　sustainable　development　based　on　the　perspectives　of　ecosystem　health,　integrity,　and　ecosystem　services　association,　characterized　by　＂contribution-sensitivity-vigour-organization＂.　An　adaptive　generation　approach　utilizing　deep　learning,　specifically　the　self-organizing　mapping　neural　network　model,　is　employed　to　overcome　the　traditional　homogenisation　problem　and　identify　various　types　of　ecological　sources　by　integrating　multi-sourced　data,　which　was　used　to　address　the　issue　of　original　information　loss　caused　by　overlay　analysis　and　homogenization　of　ecosources.　Building　upon　these　insights,　the　study　utilizes　the　minimum　cumulative　resistance　model,　gravity　model,　and　other　theories　to　extract　eco-corridors　and　nodes,　thereby　constructing　an　ESP　(20　ecological　sources,　30　ecological　corridors,　and　61　ecological　nodes)　for　PLEUA.　An　optimized　pattern　of　＂one　ring,　two　corridors,　two　zones,　and　multiple　cores＂　is　proposed　in　this　study　and　provides　policy　recommendations　for　regional　land　development　optimization　and　environmental　management　enhancement.　This　configuration　serves　as　a　crucial　reference　for　achieving　regional　spatial　optimization　and　sustainable　development　in　the　PLEUA.　Furthermore,　this　study　provides　insights　and　ideas　for　other　cities　undergoing　rapid　urbanization　to　coordinate　the　interactions　between　human　activities　and　the　ecological　security　of　natural　resources　during　the　process　of　urban　expansion,　promoting　a　healthy　and　sustainable　urban　expansion　process.
