Specific embodiment
Specific embodiment of the invention is described in detail below according to Figure of description:
It is a kind of can restoration of the ecosystem lake basins ingoing river river course structure, described river course structure include river course substrate 1, River course bank slope and river course buffer strip, tiling has one layer of vegetation type ecological blanket 101, described vegetation type in described river course substrate 1 The center on 101 4 jiaos and two sides long of ecological blanket is equipped with the bamboo pricker 102 that vegetation type ecological blanket 101 is fixed on river course substrate 1, Described vegetation type ecological blanket 101 includes blanket body and is coated on the plant life base material in portion in blanket body;The outer layer of the blanket body is nylon Stratum reticulare, the internal layer of the blanket body is burlap layer;It is described to plant raw base material by sandstone, the raw-soil and bed mud according to 0.3:1:1 ratio is mixed Conjunction is formed;The upper strata of the raw base material of described plant is provided with the seed of water plant 3, and the described seed of water plant 3 plants life located at described Between base material and the burlap layer.Tile one layer of vegetation type ecological blanket 101 in river course substrate 1, can not only improve water quality, prevent The soil erosion of river course substrate 1, moreover it is possible to for riverbed biology provides preferable habitat, the quick microecosystem for repairing riverbed, And the effect by water plant 3 suppresses the secondary pollution of pollutants in sediments, so as to improve the self-purification capacity of water body, improve water body Ecological environment;And this kind of vegetation type ecological blanket 101 is cheap, scene laying very aspect.
River course bank slope is the chief component of river land inland water ecotone, and river banks can provide biology and live, multiply Space and refuge, (can reduce slopes pore water pressure, rainfall interception, cut with bank protection function, the function that prevents erosion Weak sputter, control grogs are lost in), (vegetation on river course bank slope can recover the ecological ring of destroyed water body to improve environmental functional Border, promotes the degraded of organic pollution, and purify air adjusts miniclimate) and landscape function.
Planted on described river course bank slope and be implanted with water plant 3, described river course bank slope includes river course revetment and river course land-based area Side bank 4, described river course land-based area side bank 4 is slope, and the horizontal width of the river course land-based area side bank 4 is 3~5m;Described river course Revetment is staged revetment, and described river course revetment built by the heap of some Ecotypic Stone Mesh-boxes 2 and formed, the river course revetment from the bottom to top with This includes the first rank ecology dike 201, second-order ecology dike 202, the 3rd rank ecology dike 203, the fourth order ecology rank of dike 204 and the 5th Vertical range between ecological dike 205, and the dike face and the dike face of adjacent ecological dike of every rank ecology dike is 30cm;Described first The optional reed of kind of water plant 3 planted on rank ecology dike 201, root long grass, Lythrum salicaria, yellow flag, Scirpus tabernaemontani, cattail and Job's tears;The optional reed of kind of the water plant 3 planted on described second-order ecology dike 202, cattail, Scirpus tabernaemontani, yellow flag, Cyperus alternifolius and mullet grass;The optional reed of kind of the water plant 3 planted on described 3rd rank ecology dike 203, cattail and Scirpus tabernaemontani, the optional lotus of kind of the water plant 3 planted on the fourth order ecology dike 204 and reed, the 5th rank life The kind of the water plant 3 planted on state dike 205 is lotus.
River course buffer strip refer to beyond river course river course land-based area side bank 4 by trees (tall, shrub 7) and other vegetation groups into buffering Region;River course buffer strip has (1) ecological functions, can increase the diversity of species;Matter and energy between adjoining area Exchange;For land animals and plants provide habitat and migrate passage, for aquatile provides energy and food, improve existence ring Border;(2) safeguard function, filters runoff, absorbs nutrient, improves water quality of river;Regulation river discharge, reduces flood and drought disaster probability; Protection riverbank, stabilization river regime etc.;(3) social function, forested river course buffer strip is combined with the landscape of surrounding, riverbank, Waterfront Belts construct the landscape of a piece of green, and the place of leisure outdoor activities can be provided for the mankind, embody the mankind inherent Hydrophily;(4) Economic Function, river course buffer strip is in water, land junction, and moisture is sufficient, some wooden excellent seeds, such as Dragon spruce, fir, cypress etc., with considerable economic worth.
Planted on the river course buffer strip and be implanted with reasonably combined terrestrial plant and herbaceous plant 6, the river course buffer strip bag The first buffer strip 5, the second buffer strip 501 and the 3rd buffer strip 502 are included, the height above sea level of the second described buffer strip 501 is higher than The height above sea level of the first buffer strip 5 and the 3rd buffer strip 502;The terrestrial plant planted on described river course buffer strip includes arbor 8 and shrub 7,8 kinds of clearance spaces of plant of the arbor are 3~10m, and the root system of the prosperity of arbor 8 can consolidate riverbank, can prevent current Wash away and corrode, there is good flood fighting to act on, and for the birds and wild animals and plants that are migrated along water channel can provide food and be River provides good masking;7 kinds of clearance spaces of plant of the shrub are 100~200cm, and shrub 7 can effectively consolidate riverbank, Prevent erosion, with the collocation energy of arbor 8, the coherent and over effect of arbor 8 and ground can be played, build good landscape; The draft plant clearance space of the herbaceous plant 6 planted on the river course buffer strip is 40~120cm, and herbaceous plant 6 can increase Roughness of ground surface, enhancing improves the deposition capability of buffer strip to the penetrating power and reduction runoff velocity of rainwash.
The present invention is not only simple in structure, construction cost bottom, and can repair the ecological environment of lake basins ingoing river, Improve the water quality in river, recover the ecosystem in river, improve the self-purification capacity in river.
Some embodiments of the invention are the foregoing is only, implementation method, ordinary skill people is not all, of Any equivalent change that member is taken technical solution of the present invention by reading description of the invention, is right of the invention It is required that being covered.
