(2) be sidelong in two row timbers new riverbeds one and put willow bundle or gabion; Be sidelong at main stem one and put jackstone;
(3) from bank slope in the middle of the river course the oblique gabion groynes that is provided with to the river course;
(4) excavation a plurality of water purification brook and planting aquatic plants on new riverbed;
Advantage of the present invention and effect are:
(1) constructs new riverbed.Water purification brook on the new riverbed, water plant, gabion, willow bundle etc. form the riverbed wet land system.This system can strengthen the self-purification capacity in river, and effectively purifying water body improves the river water environmental quality, for different types of aquatile provides habitat preferably.
(2) the new main stem of structure.Because the gabion groynes is regulated the river water flow structure, makes the river vertically form pool and shoal form gradually.The mutual formation of shoal and pool can form different streamflow regimes, has satisfied the hydrobiological demand of variety classes.
(3) dry season purifying water body effectively, flood period, do not influence the original function in river course.In a word, the present invention can recover the diversity that medium and small straight river water flows, and the unification of clean dirt and flood control function is realized in the space that provides biology to perch.
Other advantages of the present invention and effect will go on to say below.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Shown in Fig. 1,2,3,4:
The present invention mainly is applicable to middle-size and small-size straight river, and its construction sequence is as follows:
Along the river road bank slope both sides original bed 1 (among Fig. 2 shown in the dotted line) is gone up nail 13 liang of rows of timber down, and is filled by native and gravelly compound 2 to the upper strata by bottom between bank slope and timber 13, forms new riverbed 3; Wide 1/3 end to the river course from hard shore protection 19 (bank slope) oblique gabion groynes 7 that is provided with in the middle of the river course; On new riverbed 3, dig out a plurality of water purification brook 4, water purification brook 4 is made of gravel 15, bottom, its riverbed is positioned under the low water level, dry season the flow through river water in water purification brook 4 under the absorption of the filtration of gravel and peripheral water plant 8, effectively purified; The entrance, riverbed is provided with gabion groynes 7; New riverbed 3 nearly shore protection planted on two sides willow bundles 9, gabion 12, water plant 8, with the water purification brook 4 common riverbed wet land systems that form; 17 upstream face one side rail stake 13 and willow bundle 9 common formation willow bundle shore protections 10 in the shoal, the one side rail stake 13 of pool 16 upstream faces, gabion 12, jackstone 14 and the compound shore protection 11 of willow bundle 9 common formations; What 4 entrance, water purification brook were provided with is gabion groynes 7, throws stone 18 in the water purification brook 4.
