Abstract
The present invention provides a construction method of a salix sungkianica revetment-biological habitat of a river erosion bank, and relates to the technical field of flood plain hygrophyte salix sungkianica revetment and biological habitat construction. The double problems that riverbank erosion is severe and biodiversity is sharply declined in the Songhua River and Heilongjiang areas are solved. The construction method comprises the following steps of (1) selecting a coastline area with the river bank eroded at bank sides of the main stream of the Songhua River or islands in the middle of the river; and (2) constructing and obtaining a salix sungkianica revetment at the erosion bank side in a manner of cutting, seedling transplanting or combination of the two modes, constructing an engineering revetment between the salix sungkianica revetment and the water for the river bank which is severely eroded, and completing construction of the salix sungkianica revetment-biological habitat of the river erosion bank. The river bank soil is fixed by means of developed roots of the salix sungkianica, erosion of river water on the river bank is reduced, the salix sungkianica can also provide aquatic birds with perch and nesting places, aquatic organisms are relatively abundant in a dense salix sungkianica system, and therefore biodiversity is improved.
Description
Technical field
The present invention relates to alluvial flat hygrophyte dryland willow shore protection and constructing technology field, biological habitat, be specifically related to a kind of construction method of channel erosion bank dryland willow shore protection-biological habitat.
Background technology
At present, downstream, Song Hua River destroys because of the mankind and water pollution causes riverine wetland to destroy seriously, and bio-diversity reduces, Function of Wetland serious degradation.Meanwhile, under Coriolis force effect, Northern Hemisphere flowing water has deflecting force to the right and then causes river right bank to occur Eroded phenomenon.Fall sharply with under the dual-pressure of bank erosion in bio-diversity, a kind of reasonable, economic and applicable riverbank recovery technique must be sought.
Dryland willow (formal name used at school: Songjiang willow Salixsungkianica, Longjiang willow Salixsachalinensis) is Heilungkiang, Songhua River Basin alluvial flat " mangrove forest " plant, growth is fast, height about 2 ~ 3 meters, stem is undeveloped, becomes Cong Zhizhuan, with luxuriant foliage and spreading branches in leafy profusion, well developed root system, have aerial root, resistance to water logging, ecological functions are strong.But, still lack the correlative study adopting dryland willow plantation to protect eroding bank and bio-diversity at present.
Summary of the invention
The object of the invention is the two fold problem fallen sharply to solve the serious and bio-diversity of Song Hua River, Heilongjiang river bank erosion, and a kind of construction method of channel erosion bank dryland willow shore protection-biological habitat is provided.
The construction method of channel erosion bank dryland willow shore protection-biological habitat of the present invention realizes according to the following steps:
One, main stream of Songhua River bank or ait is selected to there is the water front region of bank erosion as dryland willow planting site;
Two, in the method that season in the early spring adopts cuttage, seedling is planted or two kinds of modes combine dryland willow dense planting built on dryland willow planting site and obtain dryland willow shore protection, dryland willow spacing in the rows controls, at (4 ~ 10) cm × (4 ~ 10) cm, to complete the structure of channel erosion bank dryland willow shore protection-biological habitat.
The present invention is channel erosion bank plantation dryland willow, and the root system by dryland willow prosperity fixes riverbank soil, reduces river to the erosion on riverbank; Simultaneously sagging withy and exposed dense natural pond willow root system both can be fish and lay eggs and provide " attachment ", and can be again juvenile fish provides " sanctuary ", can be used as the settlement of species diversity.Aquatile relative abundance in dense dryland willow system, both can be aquatic bird and provided the environment of nesting, perching, can be again the food that aquatic bird provides certain.
In sum, the construction method of channel erosion bank dryland willow shore protection-biological habitat of the present invention, not only effectively can contain the retrogressing of caving in of downstream, Song Hua River and Heilungkiang right bank eroding bank, reduces territory loss; And exposed dryland willow root system can be fish-egg and provides " attachment ", there is the effect of " fish nest "; The root system that dryland willow is dense also can be juvenile fish and provides and perch and " taking refuge " place; Dryland willow also can be aquatic bird and provides roost and place of nesting, and contributes to the recovery of bio-diversity to a certain extent.Meanwhile, the enforcement of dryland willow shore protection ecological technique effectively can reduce engineering measures such as " T-shaped dams ", not only cost-saving, also can available protecting alluvial flat wetland.The present invention has that corrosion protection result is good, cost is low, simple to operate, easy, ecological benefits significantly, be convenient to the features such as large scale application.
