Based on the uploaded site base map, create an ecological flow and system connectivity analysis diagram in SASAKI style for international landscape architecture competition. Strictly retain the site boundary, river channel, road network, building layout and spatial scale, do not alter the site geometry.
Background: Faint light gray linework of simplified urban buildings and roads, low opacity with subtle sketch texture, quiet and unobtrusive.

Semi-transparent pale orange for Mixed-use Edge, Urban Interface, Investment Hotspot.
Semi-transparent pale blue for River Corridor.
Labels: Clean sans-serif English text labels for each zone: ECOLOGICAL CORE, PUBLIC OPEN SPACE, WATERFRONT PARK, WETLAND BUFFER, RIVER CORRIDOR, INVESTMENT HOTSPOT, GATEWAY NODE, BRIDGE CONNECTION, COMMUNITY LINK, CAMPUS EDGE, SLOW-MOBILITY LOOP.
Add a legend box at top left, clearly listing all symbols and definitions.
Overall style: Flat vector planning analysis drawing with subtle hand-sketch texture, low contrast, clear information hierarchy. No photographic texture, no heavy shadows. All text neatly arranged and fully legible. Single diagram only, no split panels.
