Ecological Conservation Method of Sandy Bank Slope in Coastal Zone

Abstract

The invention discloses an ecological solid protection method for a littoral zone sandy shore slope. The method comprises the following steps of digging a plurality of cutting holes with uniform spacing on a slope surface of the littoral zone sandy shore slope, arranging the plurality of cutting holes in rows, and placing a plurality of cutting earthen bowls in the plurality of cutting holes for later operation; spreading a plurality of straw bundles along upper end openings of the plurality of cutting holes arranged in a row; using a plurality of living body willow branch sections to penetrate through the plurality of straw bundles and to be inserted into the plurality of cutting holes one by one; digging a plurality of seeding holes uniformly in the bare slope surface among the pluralityof straw bundles, spreading straw broken fibers on the bottoms of the plurality of seeding holes, and sowing drought-resistant weed seeds above the straw broken fibers. The method combines the modesof using the straw bundles to stop and store water and soil, propagating the plurality of living body willow branches into shrub layers and forming a herbaceous layer by the drought-resistant grass species, quickly and efficiently constructs a network interlacing rooting environment in the littoral zone sandy shore slope, and achieves the purpose of ecological solid protection of the shore slope in a 'three in one' manner.

Description

technical field [0001] The invention relates to an ecological conservation method for a sandy bank slope in a coastal zone. Background technique [0002] As a corridor connecting the water body and the buffer zone, the shore slope of the coastal zone is a channel for material flow, energy flow, information flow, and species flow; it is also one of the most important habitats for organisms, which can ensure that organisms such as insects, amphibians, And the life history of birds is complete, which plays a role in regulating the microclimate of rivers. [0003] In recent years, land reclamation activities have destroyed the original swamps, wetlands, and woodlands along the river bank, making the soil and water conservation capacity of the bank slope worse and the sediment content increased; sand mining in the river channel has significantly changed the hydrodynamic force of the river, resulting in The coarse sand content of the bank slope increases, and the soil is loose; a...

Problems solved by technology

However, some engineering measures use expensive ecological bags, ecological slope protection substrates, etc., although they have achieved a certain effect of bank stabilization and slope protection, they are not conducive to large-scale promotion due to high cost
