This invention discloses a mixed-use (edible and ornamental) lake composite diverse
wetland module and its construction method, relating to the field of
wetland ecological engineering technology. It includes a primary purification unit located on the lake shoreline, a deep purification and resource
production unit located in the
open water area of the lake, and a
hydraulic connection system connecting the primary purification unit and the deep purification and resource
production unit. This mixed-use (edible and ornamental) lake composite diverse
wetland module and its construction method connects surface flow wetland units and horizontal
subsurface flow wetland units in series to form a primary purification unit. This unit is then spatially combined and hydraulically connected with an aquatic vegetable-type
floating island wetland constructed based on a bamboo frame, netting, vegetable rotation ponds, and supporting bamboo poles. A directional
water flow path including an inlet area, a wedge-shaped distribution channel, and a collection
pipe is also provided. This constructs a three-dimensional composite purification
system integrating primary interception, deep purification, and resource production, achieving
synergy between water purification efficiency and edible
plant resource production.
