METHOD FOR COMPOSING RIVER WITH LITTLE TIDEWATER FOR ECOLOGICALLY RECOVERING A FRESHWATER LAKE BY A SEAWALL

摘要

A kind of seashore for along existing fresh water lake or manufacturing one for ecological restoration by a seawater has the method for Chao He to be arranged to create advantageous environment, it is used for coastal fish and lives, by keeping a fresh water lake and sea clean and smoothly manufacturing coastal fish and nutriment. Wherein seawater and fresh water freely flow through on the side of a fresh water lake (20), the present invention relates to a kind of methods, there are Chao He (30) for manufacturing one, wherein the movement of fresh water and seawater, which passes through to be capable of forming a seawall (10) for allowing the suitable environment of Species of Rare Fish from Qingdao and be cut off, is moved to fresh water lake, it stops, safely ovum, then return to sea, supply smoothly includes the fresh water of nutriment abundant and forms a zigzag flow tube by installation one spur dike (33) and along two riverbanks in river, minimum range in fresh water lake forms a river mouth (32), one automatic floodgate (31) is installed to the upstream for having Chao He and the level that controls fresh water lake increases coastal fish, without opening a sluice in seawall.
